Subject: [GIT PULL] Please pull powerpc/linux.git powerpc-4.19-1 tag
Hi Linus,
Please pull powerpc updates for 4.19.
There's a trivial conflict in Documentation/admin-guide/kernel-parameters.txt
between our addition of nospectre_v1 and the x86 documentation for nosmt.
There's another in arch/m68k/mac/misc.c, which was coordinated with
Geert but unfortunately we still caused a conflict. The resolution is to
take the time64_t change and the CONFIG_ADB_PMU change.
The change to include/uapi/linux/pmu.h is safe and not perf related as
one would assume, the pmu there means Power Management Unit.
Finally there's the change to struct page. That was sent to linux-mm but
we couldn't tease an Ack out of anyone. Willy mentioned he wants to make
pt_mm generic in future, at which point we will happily shuffle our
field elsewhere.
cheers
The following changes since commit 021c91791a5e7e85c567452f1be3e4c2c6cb6063:
Linux 4.18-rc3 (2018-07-01 16:04:53 -0700)
are available in the git repository at:
https://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux.git tags/powerpc-4.19-1
for you to fetch changes up to a2dc009afa9ae8b92305be7728676562a104cb40:
powerpc/mm/book3s/radix: Add mapping statistics (2018-08-13 16:35:05 +1000)
--------------------------------------------------------------------
powerpc updates for 4.19
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.
