This patch provides individual system call numbers for the following
System V IPC system calls, on PowerPC, so that they do not need to be
multiplexed:
* semop, semget, semctl, semtimedop
* msgsnd, msgrcv, msgget, msgctl

Now that we always have CONFIG_PCI=y for pseries, we can stop guarding
code with CONFIG_PCI ifdefs.
Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
The pseries build with PCI=n looks to have been broken for at least 5
years, and no one's noticed or cared.
Following the obvious breakages backward, the first commit I can find
that builds is the parent of 2eb4afb69f ("powerpc/pci: Move pseries
code into pseries platform specific area") from April 2009.
A distro would never ship a PCI=n kernel, so it is only useful for folks
building custom kernels. Also on KVM the virtio devices appear on PCI,
so it would only be useful if you were building kernels specifically to
run on PowerVM and with no PCI devices.
The added code complexity, and testing load (which we've clearly not
been doing), is not justified by the small reduction in kernel size for
such a niche use case.
So just make PCI non-optional on pseries.

My recent commit d2036f30cf ("scripts/kconfig/Makefile: Allow
KBUILD_DEFCONFIG to be a target"), contained a bug in that when it
checks if KBUILD_DEFCONFIG is a file it forgets to prepend $(srctree) to
the path.
This causes the build to fail when building out of tree (with O=), and
when the value of KBUILD_DEFCONFIG is 'defconfig'. In that case we will
fail to find the 'defconfig' file, because we look in the build
directory not $(srctree), and so we will call Make again with
'defconfig' as the target. From there we loop infinitely calling 'make
defconfig' again and again.
The fix is simple, we need to look for the file under $(srctree).

We need to properly identify whether a hugepage is an explicit or
a transparent hugepage in follow_huge_addr(). We used to depend
on hugepage shift argument to do that. But in some case that can
result in wrong results. For ex:
On finding a transparent hugepage we set hugepage shift to PMD_SHIFT.
But we can end up clearing the thp pte, via pmdp_huge_get_and_clear.
We do prevent reusing the pfn page via the usage of
kick_all_cpus_sync(). But that happens after we updated the pte to 0.
Hence in follow_huge_addr() we can find hugepage shift set, but transparent
huge page check fail for a thp pte.
NOTE: We fixed a variant of this race against thp split in commit
691e95fd73
("powerpc/mm/thp: Make page table walk safe against thp split/collapse")
Without this patch, we may hit the BUG_ON(flags & FOLL_GET) in
follow_page_mask occasionally.
In the long term, we may want to switch ppc64 64k page size config to
enable CONFIG_ARCH_WANT_GENERAL_HUGETLB

Arch Makefiles can set KBUILD_DEFCONFIG to tell kbuild the name of the
defconfig that should be built by default.
However currently there is an assumption that KBUILD_DEFCONFIG points to
a file at arch/$(SRCARCH)/configs/$(KBUILD_DEFCONFIG).
We would like to use a target, using merge_config, as our defconfig, so
adapt the logic in scripts/kconfig/Makefile to allow that.
To minimise the chance of breaking anything, we first check if
KBUILD_DEFCONFIG is a file, and if so we do the old logic. If it's not a
file, then we call the top-level Makefile with KBUILD_DEFCONFIG as the
target.

powerpc has a link register (lr) used for calling functions. We "bl
<func>" to call a function, and "blr" to return back to the call site.
The lr is only a single register, so if we call another function from
inside this function (ie. nested calls), software must save away the
lr on the software stack before calling the new function. Before
returning (ie. before the "blr"), the lr is restored by software from
the software stack.
This makes branch prediction quite difficult for the processor as it
will only know the branch target just before the "blr".
To help with this, modern powerpc processors keep a (non-architected)
hardware stack of lr called a "link stack". When a "bl <func>" is
run, the lr is pushed onto this stack. When a "blr" is called, the
branch predictor pops the lr value from the top of the link stack, and
uses it to predict the branch target. Hence the processor pipeline
knows a lot earlier the branch target.
This works great but there are some cases where you call "bl" but
without a matching "blr". Once such case is when trying to determine
the program counter (which can't be read directly). Here you "bl+4;
mflr" to get the program counter. If you do this, the link stack will
get out of sync with reality, causing the branch predictor to
mis-predict subsequent function returns.
To avoid this, modern micro-architectures have a special case of bl.
Using the form "bcl 20,31,+4", ensures the processor doesn't push to
the link stack.
The 32 and 64 bit variants of __get_datapage() use a "bl; mflr" to
determine the loaded address of the VDSO. The current versions of
these attempt to use this special bl variant.
Unfortunately they use +8 rather than the required +4. Hence the
current code results in the link stack getting out of sync with
reality and hence the resulting performance degradation.
This patch moves it to bcl+4 by moving __kernel_datapage_offset out of
__get_datapage().
With this patch, running a gettimeofday() (which uses
__get_datapage()) microbenchmark we get a decent bump in performance
on POWER7/8.
For the benchmark in tools/testing/selftests/powerpc/benchmarks/gettimeofday.c

64bit gets ~4% improvement

Andy Lutomirski says:
Some dynamic loaders may be slightly faster if a GNU hash is
available.
This is unlikely to have any measurable effect on the time it takes
to resolve vdso symbols (since there are so few of them). In some
contexts, it can be a win for a different reason: if every DSO has a
GNU hash section, then libc can avoid calculating SysV hashes at
all. Both musl and glibc appear to have this optimization.

Currently, little endian is only supported on powernv and pseries,
however, Kconfigs still allow us to include other platforms in a LE
kernel, this may result in space wasting or even build error if some
BE-only platforms always assume they are built for a BE kernel. So just
modify the Kconfigs of BE-only platforms to remove them from being built
for a LE kernel.
For 32bit only platforms, nothing needs to be done, because
CPU_LITTLE_ENDIAN depends on PPC64. For 64bit supported platforms, add
CPU_BIG_ENDIAN to dependencies explicitly, so that these platforms will
be disabled for LE [Suggested-by: Cédric Le Goater <clg@fr.ibm.com>].
