ARM: SoC fixes
Volume is a little higher than usual due to a set of gpio fixes for Davinci platforms that's been around a while, still seemed appropriate to not hold off until next merge window. Besides that it's the usual mix of minor fixes, mostly corrections of small stuff in device trees. Major stability-related one is the removal of a regulator from DT on Rock960, since DVFS caused undervoltage. I expect it'll be restored once they figure out the underlying issue. -----BEGIN PGP SIGNATURE----- iQJDBAABCAAtFiEElf+HevZ4QCAJmMQ+jBrnPN6EHHcFAlwEMLEPHG9sb2ZAbGl4 b20ubmV0AAoJEIwa5zzehBx3WewP/2shRXHQ8mSwMbqLApBUgPASpGtyJsLgP4vX ROMHdfQr2nhZPu9vy973aVAztkG3FCsWNhKqNVWTfvNf9eNYRh62D8/gqNYavQJH Gtq/TpiJWWDWoXzxHpOE5vSunNDUGWRrbigmgcONogNs42iX0ngLAy7GWzWHB7oc O3HAYxNevsBTJkkKpKGnDqDM1P4WaEG5OPdjMUN25UD7IBshzuVq4eG3LuqLLZ01 NzGV/RErCnnLP8VSJlu+LQkLBeO5WpcvqZMeC6lNGBEBQAscTYRTucmM9tflJgCK B3+GczLFdJXKwluVV055MfrBxUweZ+Tm2gk7Ojtou/ozhFOdWICVT6KSwTHiOUIB ZDP/f56QfJCxxc/NFX5fJHSaYhXl+tj1HVxwG/dK/l3blMOX5I7cZkBKnjI9sDVl H3on9r5S3j1x1T534zf/n0OUwztIBmPiEZTPeoz6L1HuqpusmWJZB3knW6RnA4Lv 3JQPowK2k97/3Xp4xnzl5rQreBomXv1hsszXmPKX0pIFXF1C+BQ0LwNd9cC/Hnq2 dz02JkzoAoEg1L5DYhG63vg/3beg//3Z7uGNMu4LMcaNlLxl5AqMM7O18qJCfMth nFZRx+ZkZ7h8EJqXnMxnXgwHUzWN6Iq2AjKFfmVWRQcDZk+Ys9BlRV5O9m0N0JHb KfdtL0SC =m41T -----END PGP SIGNATURE----- Merge tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC fixes from Olof Johansson: "Volume is a little higher than usual due to a set of gpio fixes for Davinci platforms that's been around a while, still seemed appropriate to not hold off until next merge window.

While rewriting the function graph tracer, I discovered a design flaw that
was introduced by a patch that tried to fix one bug, but by doing so created another bug. As both bugs corrupt the output (but they do not crash the kernel), I decided to fix the design such that it could have both bugs fixed. The original fix, fixed time reporting of the function graph tracer when doing a max_depth of one. This was code that can test how much the kernel interferes with userspace. But in doing so, it could corrupt the time keeping of the function profiler. The issue is that the curr_ret_stack variable was being used for two different meanings. One was to keep track of the stack pointer on the ret_stack (shadow stack used by the function graph tracer), and the other use case was the graph call depth. Although, the two may be closely related, where they got updated was the issue that lead to the two different bugs that required the two use cases to be updated differently. The big issue with this fix is that it requires changing each architecture. The good news is, I was able to remove a lot of code that was duplicated within the architectures and place it into a single location. Then I could make the fix in one place. I pushed this code into linux-next to let it settle over a week, and before doing so, I cross compiled all the affected architectures to make sure that they built fine. In the mean time, I also pulled in a patch that fixes the sched_switch previous tasks state output, that was not actually correct. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCW/4NPhQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qnWAAQCyUIRLgYImr81eTl52lxNRsULk+aiI U29kRFWWU0c40AEA1X9sDF0MgOItbRGfZtnHTZEousXRDaDf4Fge2kF7Egg= =liQ0 -----END PGP SIGNATURE----- Merge tag 'trace-v4.20-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing fixes from Steven Rostedt: "While rewriting the function graph tracer, I discovered a design flaw that was introduced by a patch that tried to fix one bug, but by doing so created another bug.

arm64: Add workaround for Cortex-A76 erratum 1286807
On the affected Cortex-A76 cores (r0p0 to r3p0), if a virtual address for a cacheable mapping of a location is being accessed by a core while another core is remapping the virtual address to a new physical page using the recommended break-before-make sequence, then under very rare circumstances TLBI+DSB completes before a read using the translation being invalidated has been observed by other observers. The workaround repeats the TLBI+DSB operation and is shared with the Qualcomm Falkor erratum 1009 Reviewed-by: Suzuki K Poulose <suzuki.poulose@arm.com> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> |

arm64: function_graph: Simplify with function_graph_enter()
The function_graph_enter() function does the work of calling the function
graph hook function and the management of the shadow stack, simplifying the
work done in the architecture dependent prepare_ftrace_return().
Have arm64 use the new code, and remove the shadow stack management as well as
having to set up the trace structure.
This is needed to prepare for a fix of a design bug on how the curr_ret_stack
is used.

efi/arm: Defer persistent reservations until after paging_init()
The new memory EFI reservation feature we introduced to allow memory reservations to persist across kexec may trigger an unbounded number of calls to memblock_reserve(). The memblock subsystem can deal with this fine, but not before memblock resizing is enabled, which we can only do after paging_init(), when the memory we reallocate the array into is actually mapped. So break out the memreserve table processing into a separate routine and call it after paging_init() on arm64. On ARM, because of limited reviewing bandwidth of the maintainer, we cannot currently fix this, so instead, disable the EFI persistent memreserve entirely on ARM so we can fix it later.

arm64: memblock: don't permit memblock resizing until linear mapping is up

arm64: mm: define NET_IP_ALIGN to 0
On arm64, there is no need to add 2 bytes of padding to the start of each network buffer just to make the IP header appear 32-bit aligned. Since this might actually adversely affect DMA performance some platforms, let's override NET_IP_ALIGN to 0 to get rid of this padding.

arm64: dts: renesas: condor: switch from EtherAVB to GEther
The "official" Condor boards have always been wired to mount NFS via
GEther, not EtherAVB -- the boards resoldered for EtherAVB were local
to Cogent Embedded, so we've been having an unpleasant situation where
a "normal" Condor board still can't mount NFS (unless an EtherAVB PHY
extension board is plugged in). Switch from EtherAVB to GEther at last!

arm64: dts: rockchip: remove vdd_log from rock960 to fix a stability issues
When the performance governor is set as default, the rock960 hangs
around one minute after booting, whatever the activity is (idle, key
pressed, loaded, ...).
Based on the commit log found at https://patchwork.kernel.org/patch/10092377/
"vdd_log has no consumer and therefore will not be set to a specific
voltage. Still the PWM output pin gets configured and thence the vdd_log
output voltage will changed from it's default. Depending on the idle
state of the PWM this will slightly over or undervoltage the logic supply
of the RK3399 and cause instability with GbE (undervoltage) and PCIe
(overvoltage). Since the default value set by a voltage divider is the
correct supply voltage and we don't need to change it during runtime we
remove the rail from the devicetree completely so the PWM pin will not
be configured."
After removing the vdd-log from the rock960's specific DT, the board
does no longer hang and shows a stable behavior.
Apply the same change for the rock960 by removing the vdd-log from the
DT.

arm64: makefile fix build of .i file in external module case
After 'a66649dab350 arm64: fix vdso-offsets.h dependency' if one will try to build .i file in case of external kernel module, build fails complaining that prepare0 target is missing. This issue came up with SystemTap when it tries to build variety of .i files for its own generated kernel modules trying to figure given kernel features/capabilities. The issue is that prepare0 is defined in top level Makefile only if KBUILD_EXTMOD is not defined. .i file rule depends on prepare and in case KBUILD_EXTMOD defined top level Makefile contains empty rule for prepare. But after mentioned commit arch/arm64/Makefile would introduce dependency on prepare0 through its own prepare target. Fix it to put proper ifdef KBUILD_EXTMOD around code introduced by mentioned commit. It matches what top level Makefile does.

Pull stackleak gcc plugin from Kees Cook:
"Please pull this new GCC plugin, stackleak, for v4.20-rc1. This plugin
was ported from grsecurity by Alexander Popov. It provides efficient
stack content poisoning at syscall exit. This creates a defense
against at least two classes of flaws:
- Uninitialized stack usage. (We continue to work on improving the
compiler to do this in other ways: e.g. unconditional zero init was
proposed to GCC and Clang, and more plugin work has started too).
- Stack content exposure. By greatly reducing the lifetime of valid
stack contents, exposures via either direct read bugs or unknown
cache side-channels become much more difficult to exploit. This
complements the existing buddy and heap poisoning options, but
provides the coverage for stacks.
The x86 hooks are included in this series (which have been reviewed by
Ingo, Dave Hansen, and Thomas Gleixner). The arm64 hooks have already
been merged through the arm64 tree (written by Laura Abbott and
reviewed by Mark Rutland and Will Deacon).
With VLAs having been removed this release, there is no need for
alloca() protection, so it has been removed from the plugin"

memblock: stop using implicit alignment to SMP_CACHE_BYTES
When a memblock allocation APIs are called with align = 0, the alignment is implicitly set to SMP_CACHE_BYTES. Implicit alignment is done deep in the memblock allocator and it can come as a surprise. Not that such an alignment would be wrong even when used incorrectly but it is better to be explicit for the sake of clarity and the prinicple of the least surprise. Replace all such uses of memblock APIs with the 'align' parameter explicitly set to SMP_CACHE_BYTES and stop implicit alignment assignment in the memblock internal allocation functions. For the case when memblock APIs are used via helper functions, e.g. like iommu_arena_new_node() in Alpha, the helper functions were detected with Coccinelle's help and then manually examined and updated where appropriate. The direct memblock APIs users were updated using the semantic patch below: @@ expression size, min_addr, max_addr, nid; @@ ( | - memblock_alloc_try_nid_raw(size, 0, min_addr, max_addr, nid) + memblock_alloc_try_nid_raw(size, SMP_CACHE_BYTES, min_addr, max_addr, nid) | - memblock_alloc_try_nid_nopanic(size, 0, min_addr, max_addr, nid) + memblock_alloc_try_nid_nopanic(size, SMP_CACHE_BYTES, min_addr, max_addr, nid) | - memblock_alloc_try_nid(size, 0, min_addr, max_addr, nid) + memblock_alloc_try_nid(size, SMP_CACHE_BYTES, min_addr, max_addr, nid) | - memblock_alloc(size, 0) + memblock_alloc(size, SMP_CACHE_BYTES) | - memblock_alloc_raw(size, 0) + memblock_alloc_raw(size, SMP_CACHE_BYTES) | - memblock_alloc_from(size, 0, min_addr) + memblock_alloc_from(size, SMP_CACHE_BYTES, min_addr) | - memblock_alloc_nopanic(size, 0) + memblock_alloc_nopanic(size, SMP_CACHE_BYTES) | - memblock_alloc_low(size, 0) + memblock_alloc_low(size, SMP_CACHE_BYTES) | - memblock_alloc_low_nopanic(size, 0) + memblock_alloc_low_nopanic(size, SMP_CACHE_BYTES) | - memblock_alloc_from_nopanic(size, 0, min_addr) + memblock_alloc_from_nopanic(size, SMP_CACHE_BYTES, min_addr) | - memblock_alloc_node(size, 0, nid) + memblock_alloc_node(size, SMP_CACHE_BYTES, nid) ) [mhocko@suse.com: changelog update] [akpm@linux-foundation.org: coding-style fixes] [rppt@linux.ibm.com: fix missed uses of implicit alignment] Link: http://lkml.kernel.org/r/20181016133656.GA10925@rapoport-lnx Link: http://lkml.kernel.org/r/1538687224-17535-1-git-send-email-rppt@linux.vnet.ibm.com Signed-off-by: Mike Rapoport <rppt@linux.vnet.ibm.com> Suggested-by: Michal Hocko <mhocko@suse.com> Acked-by: Paul Burton <paul.burton@mips.com> [MIPS] Acked-by: Michael Ellerman <mpe@ellerman.id.au> [powerpc] Acked-by: Michal Hocko <mhocko@suse.com> Cc: Catalin Marinas <catalin.marinas@arm.com> Cc: Chris Zankel <chris@zankel.net> Cc: Geert Uytterhoeven <geert@linux-m68k.org> Cc: Guan Xuetao <gxt@pku.edu.cn> Cc: Ingo Molnar <mingo@redhat.com> Cc: Matt Turner <mattst88@gmail.com> Cc: Michal Simek <monstr@monstr.eu> Cc: Richard Weinberger <richard@nod.at> Cc: Russell King <linux@armlinux.org.uk> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Tony Luck <tony.luck@intel.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

ARM: SoC platform updates for 4.20
A couple of platforms change hands in the MAINTAINERS file:
- Linus Walleij lists himself for the ARM Reference platforms:
versatile, vexpress, integrator and realview. He has been the main
contributor for these for a while, and makes it official now.
- Vladimir Zapolskiy takes over the LPC18xx platform from Joachim Eastwood
- Manivannan Sadhasivam becomes a secondary maintainer for the
Actions Semi machines
- Nicolas Ferre lists updates the MAINTAINER listing for the AT91
platform: Ludovic Desroches is now a co-maintainer for the platform, and
several other people (Claudiu Beznea, Cristian Birsan, Eugen Hristev,
Codrin Ciubotariu) take over individual device drivers.
Thanks everyone for working on this, and welcome to the new maintainers!
The "virt" platform on qemy or kvm can now be used in big-endian mode
without additional tricks, thanks to Jason Donenfeld.
Once again, we gain support for another NXP i.MX6 variant, this time
it's the i.MX 6ULZ 32-bit single-core version.
On arm64, we add support for two SoCs from Renesas: RZ/G2E (r8a774c0)
and RZ/G2M (r8a774a1). These are described as microcontrollers on the
manufacturer website, but appear to be rather powerful. The RZ/G2M is
used on the reference board for the CIP Super Long Term Support (SLTS)
Linux Kernels.

ARM: SoC driver updates for 4.17
The most noteworthy SoC driver changes this time include:
- The TEE subsystem gains an in-kernel interface to access the TEE
from device drivers.
- The reset controller subsystem gains a driver for the Qualcomm
Snapdragon 845 Power Domain Controller.
- The Xilinx Zynq platform now has a firmware interface for its
platform management unit. This contains a firmware "ioctl" interface
that was a little controversial at first, but the version we merged
solved that by not exposing arbitrary firmware calls to user space.
- The Amlogic Meson platform gains a "canvas" driver that is used
for video processing and shared between different high-level drivers.
The rest is more of the usual, mostly related to SoC specific power
management support and core drivers in drivers/soc:
- Several Renesas SoCs (RZ/G1N, RZ/G2M, R-Car V3M, RZ/A2M) gain new
features related to power and reset control.
- The Mediatek mt8183 and mt6765 SoC platforms gain support for
their respective power management chips.
- A new driver for NXP i.MX8, which need a firmware interface for
power management.
- The SCPI firmware interface now contains support estimating power
usage of performance states
- The NVIDIA Tegra "pmc" driver gains a few new features, in particular
a pinctrl interface for configuring the pads.
- Lots of small changes for Qualcomm, in particular the "smem"
device driver.
- Some cleanups for the TI OMAP series related to their sysc
controller.
Additional cleanups and bugfixes in SoC specific drivers include the
Meson, Keystone, NXP, AT91, Sunxi, Actions, and Tegra platforms.

- The Xilinx Zynq platform now has a firmware interface for its
platform management unit. This contains a firmware "ioctl"
interface that was a little controversial at first, but the version
we merged solved that by not exposing arbitrary firmware calls to
user space.
- The Amlogic Meson platform gains a "canvas" driver that is used for
video processing and shared between different high-level drivers.
The rest is more of the usual, mostly related to SoC specific power
management support and core drivers in drivers/soc:
- Several Renesas SoCs (RZ/G1N, RZ/G2M, R-Car V3M, RZ/A2M) gain new
features related to power and reset control.
- The Mediatek mt8183 and mt6765 SoC platforms gain support for their
respective power management chips.
- A new driver for NXP i.MX8, which need a firmware interface for
power management.
- The SCPI firmware interface now contains support estimating power
usage of performance states
- The NVIDIA Tegra "pmc" driver gains a few new features, in
particular a pinctrl interface for configuring the pads.
- Lots of small changes for Qualcomm, in particular the "smem" device
driver.
- Some cleanups for the TI OMAP series related to their sysc
controller.
Additional cleanups and bugfixes in SoC specific drivers include the
Meson, Keystone, NXP, AT91, Sunxi, Actions, and Tegra platforms"

ARM: SoC defconfig updates
The defconfig changes are split out from the rest again. This time we have a number of changes for NXP i.MX and Renesas, including a cleanup of old options. Some smaller changes are for Socionext Uniphier, Allwinner, Qualcomm, Rockchip, Renesas, AT91, Hisilicon, and STM32. All of these just enable platform specific device drivers.

ARM: SoC device tree updates for 4.20
There are close to 800 indivudal changesets in this branch again, which feels like a lot. There are particularly many changes for the NVIDIA Tegra platform this time, in fact more than it has seen in the two years since the v4.9 merge window. Aside from this, it's been fairly normal, with lots of changes going into Renesas R-CAR, NXP i.MX, Allwinner Sunxi, Samsung Exynos, and TI OMAP. Most of the changes are for adding new features into existing boards, for brevity I'm only mentioning completely new machines and SoCs here. For the first time I think we have (slightly) more new 64-bit hardware than 32-bit: Two boards get added for TI OMAP: Moxa UC-2101 is an industrial computer, see https://www.moxa.com/product/UC-2100.htm; GTA04A5 is a minor variation of the motherboards of the GTA04 phone, see https://shop.goldelico.com/wiki.php?page=GTA04A5 Clearfog is a nice little board for quad-core Marvell Armada 8040 network processor, see https://www.solid-run.com/marvell-armada-family/clearfog-gt-8k/ Two additional server boards come with the Aspeed baseboard management controllers: Stardragon4800 is an arm64 reference platform made by HXT (based on Qualcomm's server chips), and TiogaPass is an Open Compute mainboard with x86 CPUs. Both use the ARM11 based AST2500 chips in the BMC. NXP i.MX usually sees a lot of new boards each release. This time there we only add one minor variant: ConnectCore 6UL SBC Pro uses the same SoM design as the ConnectCore 6UL SBC Express added later. However, there is a new chip, the i.MX6ULZ, which is an even smaller variant of the i.MX6ULL, with features removed. There is also support for the reference board design, the i.MX6ULZ 14x14 EVK. A new Raspberry Pi variant gets added, this one is the CM3 compute module based on bcm2837, it was launched in early 2017 but only now added to the kernel, both as 32-bit and as 64-bit files, as we tend to do for Raspberry Pi. On the Allwinner side, everything is again about cheap development boards, usually of the "Fruit Pi" variety. The new ones this time are: Orange Pi Zero Plus2: http://www.orangepi.org/OrangePiZeroPlus2/ Orange Pi One Plus: http://www.orangepi.org/OrangePiOneplus/ Pine64 LTS: https://www.pine64.org/?product=pine-a64-lts Banana Pi M2+ H5: http://www.banana-pi.org/m2plus.html The last one of these is now a 64-bit version of the earlier Banana Pi M2+ H3, with the same board layout. Similarly, for Rockchips, get get another variant of the 32-bit Asus Tinker board, the model 'S' based on rk3288, and three now boards based on the popular RK3399 chip: ROC-RK3399-PC: https://libre.computer/products/boards/roc-rk3399-pc/ Rock960: https://www.96boards.org/product/rock960/ RockPro64: https://www.pine64.org/?page_id=61454 These are all quite powerful boards with lots of RAM and I/O, and the RK3399 is the same chip used in several Chromebooks. Finally, we get support for the PX30 (aka rk3326) chip, which is based on the low-end 64-bit Cortex-A35 CPU core. So far, only the evaluation board is supported. One more Banana Pi is added with a Mediatek chip: Banana Pi R64 is based on the MT7622 WiFi router platform, and the first product I've seen with a 64-bit Mediatek chip in that market: http://www.banana-pi.org/r64.html For HiSilicon, we gain support for the Hi3670 SoC and HiKey 370 development board, which are similar to the Hi3660 and Hikey 360 respectively, but add support for an NPU. Amlogic gets initial support for the Meson-G12A chip (S905D2), another quad-core Cortex-A53 SoC, and its evaluation platform. On the 32-bit side, we gain support for an actual end-user product, the Endless Computers Endless Mini based on Meson8b (S805), see https://endlessos.com/computers/ Qualcomm adds support for their MSM8998 SoC and evaluation platform. This chip is commonly known as the Snapdragon 835, and is used in high-end phones as well as low-end laptops. For Renesas, a very bare support for the r8a774a1 (RZ/G2M) is added, but no boards for this one. However, we do add boards for the previously added r8a77965 (R-Car M3-N): the M3NULCB Kingfisher and the M3NULCB Starter Kit Pro. While we have lots of DT changes for NVIDIA to update the existing files, the only board that gets added is the Toradex Colibri T20 on Colibri Evaluation Board for the old Tegra2. Synaptics add support for their AS370 SoC, which is part of the (formerly Marvell) Berlin line of set-top-box chips used e.g. in the various Google Chromecast. Only the .dtsi gets added at this point, no actual machines. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJb1224AAoJEGCrR//JCVIn9uYP/jLMoGkVQRS5L9sRjOci1l5b EHl8veJ+uNJaTStp5XAZk90MoBcSdXtnISSEiR7a3qKJw1mYfgAWyPtQCttRFUCo rDp4GJpJ96TBg1tyt5Lop3V9eIYbCh9epf2foKTTdpRiX022AFk1031jvnh2Teuy fKA2VNeoyyOZqxh0ysJq7G8kWt8PTQTKXDebYPWEbsu0AFmqQ84lz7oGNdPk0GPm krtQIO6rh+sJR/8wWGYfnTYAIOk6jNrPhiyjEcyu+x2525rwKxJNKVY8P9PuNhrl hzqld1dPtb3gfdcxWxZUznHmVUGkVEIa1QNC6csSmLzuxqJJE0/J5u2P8lIfrhVI c5C8r3eaTxFM0s5uKhNhhewlJ6uiDhUQy13AG0JXteujP23BGObYstnV10pJrH75 xq7uSUiU04v95MocPjodJ2I7dIlAoFCd6ELnsmD/mz743gY9AZ6DHaOBMMwIzK3H EQifF5E/4PWOjBx7fonumBm0LebPjWGmv4CNyCK5Q93ylK7U/kFDdjiNjNhyks5E CVQBFhA7sshKJQRDOiaofMxOfKJHeKGU2PR7yGRpT3YWQD/apIL/elG4qUNjLX46 2Dwdgq8nDdbY2SzPwwy7ncTtyDRYcsFCtScT5slu1I1UxIhwEYJurzCKDM4jJNZb Cg2D7a+AlZ8N5Vsr1ldV =yaED -----END PGP SIGNATURE----- Merge tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC device tree updates from Arnd Bergmann: "There are close to 800 indivudal changesets in this branch again, which feels like a lot.
