Florian Fainelli 3dc6475c0c bcm63xx_enet: add support Broadcom BCM6345 Ethernet
This patch adds support for the Broadcom BCM6345 SoC Ethernet. BCM6345
has a slightly different and older DMA engine which requires the
following modifications:

- the width of the DMA channels on BCM6345 is 64 bytes vs 16 bytes,
  which means that the helpers enet_dma{c,s} need to account for this
  channel width and we can no longer use macros

- BCM6345 DMA engine does not have any internal SRAM for transfering
  buffers

- BCM6345 buffer allocation and flow control is not per-channel but
  global (done in RSET_ENETDMA)

- the DMA engine bits are right-shifted by 3 compared to other DMA
  generations

- the DMA enable/interrupt masks are a little different (we need to
  enabled more bits for 6345)

- some register have the same meaning but are offsetted in the ENET_DMAC
  space so a lookup table is required to return the proper offset

The MAC itself is identical and requires no modifications to work.

Maxime Bizon 6f00a02296 bcm63xx_enet: add support for Broadcom BCM63xx integrated gigabit switch
Newer Broadcom BCM63xx SoCs: 6328, 6362 and 6368 have an integrated switch
which needs to be driven slightly differently from the traditional
external switches. This patch introduces changes in arch/mips/bcm63xx in order
to:

- register a bcm63xx_enetsw driver instead of bcm63xx_enet driver
- update DMA channels configuration & state RAM base addresses
- add a new platform data configuration knob to define the number of
  ports per switch/device and force link on some ports
- define the required switch registers

On the driver side, the following changes are required:

- the switch ports need to be polled to ensure the link is up and
  running and RX/TX can properly work
- basic switch configuration needs to be performed for the switch to
  forward packets to the CPU
- update the MIB counters since the integrated

Maxime Bizon 0ae99b5fed bcm63xx_enet: split DMA channel register accesses
The current bcm63xx_enet driver always uses bcmenet_shared_base whenever
it needs to access DMA channel configuration space or access the DMA
channel state RAM. Split these register in 3 parts to be more accurate:

- global DMA configuration
- per DMA channel configuration space
- per DMA channel state RAM space

This is preliminary to support new chips where the global DMA
configuration remains the same, but there is a varying number of DMA
channels located at a different memory offset.

Peter Zijlstra 29eb77825c arch, mm: Remove tlb_fast_mode()
Since the introduction of preemptible mmu_gather TLB fast mode has been
broken. TLB fast mode relies on there being absolutely no concurrency;
it frees pages first and invalidates TLBs later.

However now we can get concurrency and stuff goes *bang*.

This patch removes all tlb_fast_mode() code; it was found the better
option vs trying to patch the hole by entangling tlb invalidation with
the scheduler.

Matt Fleming 65694c5aad x86/PCI: Map PCI setup data with ioremap() so it can be in highmem
f9a37be0f0 ("x86: Use PCI setup data") added support for using PCI ROM
images from setup_data.  This used phys_to_virt(), which is not valid for
highmem addresses, and can cause a crash when booting a 32-bit kernel via
the EFI boot stub.

pcibios_add_device() assumes that the physical addresses stored in
setup_data are accessible via the direct kernel mapping, and that calling
phys_to_virt() is valid.  This isn't guaranteed to be true on x86 where the
direct mapping range is much smaller than on x86-64.

Calling phys_to_virt() on a highmem address results in the following:

 BUG: unable to handle kernel paging request at 39a3c198
 IP: [<c262be0f>] pcibios_add_device+0x2f/0x90
 ...
 Call Trace:
  [<c2370c73>] pci_device_add+0xe3/0x130

  [<c23b7203>] acpi_pci_root_add+0x312/0x42f
  ...

The solution is to use ioremap() instead of phys_to_virt() to map the
setup data into the kernel address space.

Andre Przywara e8180dcaa8 ARM: KVM: prevent NULL pointer dereferences with KVM VCPU ioctl
Some ARM KVM VCPU ioctls require the vCPU to be properly initialized
with the KVM_ARM_VCPU_INIT ioctl before being used with further
requests. KVM_RUN checks whether this initialization has been
done, but other ioctls do not.
Namely KVM_GET_REG_LIST will dereference an array with index -1
without initialization and thus leads to a kernel oops.
Fix this by adding checks before executing the ioctl handlers.

Chen Gang ea99b1adf2 parisc: kernel: using strlcpy() instead of strcpy()
'boot_args' is an input args, and 'boot_command_line' has a fix length.
So use strlcpy() instead of strcpy() to avoid memory overflow.

Paul Bolle 766039022a parisc: rename "CONFIG_PA7100" to "CONFIG_PA7000"
There's a Makefile line setting cflags for CONFIG_PA7100. But that
Kconfig macro doesn't exist. There is a Kconfig symbol PA7000, which
covers both PA7000 and PA7100 processors. So let's use the corresponding
Kconfig macro.

kpageflags_read() walks through the whole memory, even if some memory
areas are physically not available. So, we should better not BUG on an
unavailable pfn in pfn_to_nid() but just return the expected value -1 or
0.

Chen Gang 3f108de96b parisc: memory overflow, 'name' length is too short for using
'path.bc[i]' can be asigned by PCI_SLOT() which can '> 10', so sizeof(6
* "%u:" + "%u" + '\0') may be 21.

Since 'name' length is 20, it may be memory overflow.

And 'path.bc[i]' is 'unsigned char' for printing, we can be sure the
max length of 'name' must be less than 28.

So simplify thinking, we can use 28 instead of 20 directly, and do not
think of whether 'patchc.bc[i]' can '> 100'.

Pull powerpc fixes from Ben Herrenschmidt:
 "Here are a few more fixes for powerpc 3.10.  It's a bit more than I
  would have liked this late in the game but I suppose that's what
  happens with a brand new chip generation coming out.

  A few regression fixes, some last minute fixes for new P8 features
  such as transactional memory,...

  There's also one powerpc KVM patch that I requested that adds two
  missing functions to our in-kernel interrupt controller support which
  is itself a new 3.10 feature.  These are defined by the base
  hypervisor specification.  We didn't implement them originally because
  Linux doesn't use them but they are simple and I'm not comfortable
  having a half-implemented interface in 3.10 and having to deal with
  versionning etc...  later when something starts needing those calls.
  They cannot be emulated in qemu when using in-kernel interrupt
  controller (not enough shared state).

  Just added a last minute patch to fix a typo introducing a breakage in
  our cputable for Power7+ processors, sorry about that, but the
  regression it fixes just hurt me :-)"
