In Kbuild, if_changed and friends must have FORCE as a prerequisite.
Hence, $(filter-out FORCE,$^) or $(filter-out $(PHONY),$^) is a common
idiom to get the names of all the prerequisites except phony targets.
Add real-prereqs as a shorthand.
Note:
We cannot replace $(filter %.o,$^) in cmd_link_multi-m because $^ may
include auto-generated dependencies from the .*.cmd file when a single
object module is changed into a multi object module. Refer to commit
69ea912fda ("kbuild: remove unneeded link_multi_deps"). I added some

mpc8641_hpcn was updated to 4-cell interrupt specifiers, but
PCI interrupt-map was not updated. It was also missing #interrupt-cells
on the outer PCI buses.
p1020rdb-pc was updated to 4-cell interrupt specifiers, but
the ethernet-phy nodes weren't updated.
mpc832x_rdb had an invalid "interrupts = <0>" on the ethernet-phy nodes.
Besides being the wrong number of cells, 0 is not a valid IPIC interrupt
according to ipic.c. Presumably it was meant to indicate that these
PHYs are not connected to an interrupt.

The bamboo dts has a bug: it uses a non-naturally aligned range
for PCI memory space. This isnt' supported by the code, thus
causing PCI to break on this system.
This is due to the fact that while the chip memory map has 1G
reserved for PCI memory, it's only 512M aligned. The code doesn't
know how to split that into 2 different PMMs and fails, so limit
the region to 512M.

In commit 5e9dcb6188 ("powerpc/boot: Expose Kconfig symbols to
wrapper") we added a dependency to serial.c on autoconf.h:
$(obj)/serial.c: $(obj)/autoconf.h
This works when building in-tree (ie. with KBUILD_OUTPUT unset)
because the obj tree is the src tree.
But when building with eg. O=build and -j 1 the build fails:
gcc ... -I../arch/powerpc/boot -c -o arch/powerpc/boot/serial.o arch/powerpc/boot/serial.c
gcc: error: arch/powerpc/boot/serial.c: No such file or directory
Why this is only happening with -j 1 is not clear, when building with
-j greater than 1 somehow we decide to look for serial.c in the src
tree (../), eg:
gcc -I../arch/powerpc/boot -c -o arch/powerpc/boot/serial.o ../arch/powerpc/boot/serial.c
Regardless we shouldn't be specifying a dependency on serial.c in the
build tree, we want to add a dependency to the version in $(srctree)
so fix the rule to say that.

Commit 6975a783d7 ("powerpc/boot: Allow building the zImage wrapper
as a relocatable ET_DYN", 2011-04-12) changed the procedure descriptor
at the start of crt0.S to have a hard-coded start address of 0x500000
rather than a reference to _zimage_start, presumably because having
a reference to a symbol introduced a relocation which is awkward to
handle in a position-independent executable. Unfortunately, what is
at 0x500000 in the COFF image is not the first instruction, but the
procedure descriptor itself, that is, a word containing 0x500000,
which is not a valid instruction. Hence, booting a COFF zImage
results in a "DEFAULT CATCH!, code=FFF00700" message from Open
Firmware.
This fixes the problem by (a) putting the procedure descriptor in the
data section and (b) adding a branch to _zimage_start as the first
instruction in the program.

...
Notable changes:
- A large series to rewrite our SLB miss handling, replacing a lot of fairly
complicated asm with much fewer lines of C.
- Following on from that, we now maintain a cache of SLB entries for each
process and preload them on context switch. Leading to a 27% speedup for our
context switch benchmark on Power9.
- Improvements to our handling of SLB multi-hit errors. We now print more debug
information when they occur, and try to continue running by flushing the SLB
and reloading, rather than treating them as fatal.
- Enable THP migration on 64-bit Book3S machines (eg. Power7/8/9).
- Add support for physical memory up to 2PB in the linear mapping on 64-bit
Book3S. We only support up to 512TB as regular system memory, otherwise the
percpu allocator runs out of vmalloc space.
- Add stack protector support for 32 and 64-bit, with a per-task canary.
- Add support for PTRACE_SYSEMU and PTRACE_SYSEMU_SINGLESTEP.
- Support recognising "big cores" on Power9, where two SMT4 cores are presented
to us as a single SMT8 core.
- A large series to cleanup some of our ioremap handling and PTE flags.
- Add a driver for the PAPR SCM (storage class memory) interface, allowing
guests to operate on SCM devices (acked by Dan).
- Changes to our ftrace code to handle very large kernels, where we need to use
a trampoline to get to ftrace_caller().
Many other smaller enhancements and cleanups.

Merge tag 'powerpc-4.20-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc updates from Michael Ellerman:
"Notable changes:
- A large series to rewrite our SLB miss handling, replacing a lot of
fairly complicated asm with much fewer lines of C.
- Following on from that, we now maintain a cache of SLB entries for
each process and preload them on context switch. Leading to a 27%
speedup for our context switch benchmark on Power9.
- Improvements to our handling of SLB multi-hit errors. We now print
more debug information when they occur, and try to continue running
by flushing the SLB and reloading, rather than treating them as
fatal.
- Enable THP migration on 64-bit Book3S machines (eg. Power7/8/9).
- Add support for physical memory up to 2PB in the linear mapping on
64-bit Book3S. We only support up to 512TB as regular system
memory, otherwise the percpu allocator runs out of vmalloc space.
- Add stack protector support for 32 and 64-bit, with a per-task
canary.
- Add support for PTRACE_SYSEMU and PTRACE_SYSEMU_SINGLESTEP.
- Support recognising "big cores" on Power9, where two SMT4 cores are
presented to us as a single SMT8 core.
- A large series to cleanup some of our ioremap handling and PTE
flags.
- Add a driver for the PAPR SCM (storage class memory) interface,
allowing guests to operate on SCM devices (acked by Dan).
- Changes to our ftrace code to handle very large kernels, where we
need to use a trampoline to get to ftrace_caller().
And many other smaller enhancements and cleanups.

The boot wrapper is currently built with -Os. By building with O2 we
can meaningfully reduce the time decompressing the kernel.
I tested by comparing 10 runs of each option in Qemu and on hardware.
The kernel is compressed with KERNEL_XZ built with GCC 8.2.0-7ubuntu1.
The values are counts of the timebase.
Qemu TCG powernv Power8:
Os O2 O3
median 10221123889 6201518438 6568186825
stddev 1361267211 429090641 657930076
improvement 39.33% 35.74%
Palmetto Power8:
Os O2 O3
median 50279 50599 35790
stddev 992144533 627130655 623721078
improvement 36.79% 37.13%
Romulus Power9:
Os O2 O3
median 670312391 454733720 448881398
stddev 157569 107276 108760
improvement 32.16% 33.03%
TCG was quite noisy, with every few runs producing an outlier. Even so,
O2 is faster than O3. On hardware the numbers were less noisy and O3 is
slightly faster than O2.
The wrapper size increases when moving from Os. Comparing zImage.epapr
to the existing Os build using bloat-o-meter:
Before=43401, After=56837 (13KB), chg +30.96%
Before=43401, After=64305 (20KB), chg +48.16%
I chose O2 for a balance between Qemu and hardware speed up.

This will avoid auto-vectorisation when building with higher
optimisation levels.
We don't know if the machine can support VSX and even if it's present
it's probably not going to be enabled at this point in boot.

compiler version supported by upstream, thanks to Segher for the

As of commit 10c77dba40 ("powerpc/boot: Fix build failure in 32-bit
boot wrapper") the opal code is hidden behind CONFIG_PPC64_BOOT_WRAPPER,
but the boot wrapper avoids include/linux, so it does not get the normal
Kconfig flags.
We can drop the guard entirely as in commit f8e8e69cea ("powerpc/boot:
Only build OPAL code when necessary") the makefile only includes opal.c
in the build if CONFIG_PPC64_BOOT_WRAPPER is set.

Currently the wrapper is built without including anything in
$(src)/include/, which means there are no CONFIG_ symbols defined.
This means the platform specific serial drivers were never enabled.
We now copy the definitions into the boot directory, so any C file can
now include autoconf.h to depend on configuration options.

Enable the 'dtbs' target for powerpc. This allows building all the dts

Align powerpc with other architectures which build the dtb files in the
same directory as the dts files. This is also in line with most other
build targets which are located in the same directory as the source.
This move will help enable the 'dtbs' target which builds all the dtbs
regardless of kernel config.
This transition could break some scripts if they expect dtb files in the
old location.

When building with clang crt0's _zimage_start is not marked weak, which
breaks the build when linking the kernel image:
$ objdump -t arch/powerpc/boot/crt0.o |grep _zimage_start$
0000000000000058 g .text 0000000000000000 _zimage_start
ld: arch/powerpc/boot/wrapper.a(crt0.o): in function '_zimage_start':
(.text+0x58): multiple definition of '_zimage_start';
arch/powerpc/boot/pseries-head.o:(.text+0x0): first defined here
Clang requires the .weak directive to appear after the symbol is
declared. The binutils manual says:
This directive sets the weak attribute on the comma separated list of
symbol names. If the symbols do not already exist, they will be
created.
So it appears this is different with clang. The only reference I could
see for this was an OpenBSD mailing list post[1].
Changing it to be after the declaration fixes building with Clang, and
still works with GCC.
$ objdump -t arch/powerpc/boot/crt0.o |grep _zimage_start$
0000000000000058 w .text 0000000000000000 _zimage_start

Notable changes:
- A fix for a bug in our page table fragment allocator, where a page table page
could be freed and reallocated for something else while still in use, leading
to memory corruption etc. The fix reuses pt_mm in struct page (x86 only) for
a powerpc only refcount.
- Fixes to our pkey support. Several are user-visible changes, but bring us in
to line with x86 behaviour and/or fix outright bugs. Thanks to Florian Weimer
for reporting many of these.
- A series to improve the hvc driver & related OPAL console code, which have
been seen to cause hardlockups at times. The hvc driver changes in particular
have been in linux-next for ~month.
- Increase our MAX_PHYSMEM_BITS to 128TB when SPARSEMEM_VMEMMAP=y.
- Remove Power8 DD1 and Power9 DD1 support, neither chip should be in use
anywhere other than as a paper weight.
- An optimised memcmp implementation using Power7-or-later VMX instructions
- Support for barrier_nospec on some NXP CPUs.
- Support for flushing the count cache on context switch on some IBM CPUs
(controlled by firmware), as a Spectre v2 mitigation.
- A series to enhance the information we print on unhandled signals to bring it
into line with other arches, including showing the offending VMA and dumping
the instructions around the fault.
