[PATCH] x86/xen: add call of speculative_store_bypass_ht_init() to pv paths

by Juergen Gross

Commit 1f50ddb4f4189243c05926b842dc1a0332195f31 ("x86/speculation: Handle HT correctly on AMD") added speculative_store_bypass_ht_init() to the per-cpu initialization sequence. speculative_store_bypass_ht_init() needs to be called on each cpu for pv guests, too.

+ slub-track-number-of-slabs-irrespective-of-config_slub_debug.patch added to -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: slub: track number of slabs irrespective of CONFIG_SLUB_DEBUG has been added to the -mm tree. Its filename is slub-track-number-of-slabs-irrespective-of-config_slub_debug.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/slub-track-number-of-slabs-irrespe… and later at http://ozlabs.org/~akpm/mmotm/broken-out/slub-track-number-of-slabs-irrespe… Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Shakeel Butt <shakeelb(a)google.com> Subject: slub: track number of slabs irrespective of CONFIG_SLUB_DEBUG For !CONFIG_SLUB_DEBUG, SLUB does not maintain the number of slabs allocated per node for a kmem_cache. Thus, slabs_node() in __kmem_cache_empty(), __kmem_cache_shrink() and __kmem_cache_destroy() will always return 0 for such config. This is wrong and can cause issues for all users of these functions. In fact in [1] Jason has reported a system crash while using SLUB without CONFIG_SLUB_DEBUG. The reason was the usage of slabs_node() by __kmem_cache_empty(). The right solution is to make slabs_node() work even for !CONFIG_SLUB_DEBUG. The commit 0f389ec63077 ("slub: No need for per node slab counters if !SLUB_DEBUG") had put the per node slab counter under CONFIG_SLUB_DEBUG because it was only read through sysfs API and the sysfs API was disabled on !CONFIG_SLUB_DEBUG. However the users of the per node slab counter assumed that it will work in the absence of CONFIG_SLUB_DEBUG. So, make the counter work for !CONFIG_SLUB_DEBUG. Please note that f9e13c0a5a33 ("slab, slub: skip unnecessary kasan_cache_shutdown()") exposed this issue but it is present even before.

[PATCH] MIPS: Always use -march=<arch>, not -<arch> shortcuts

by Paul Burton

The VDSO Makefile filters CFLAGS to select a subset which it uses whilst building the VDSO ELF. One of the flags it allows through is the -march= flag that selects the architecture/ISA to target. Unfortunately in cases where CONFIG_CPU_MIPS32_R{1,2}=y and the toolchain defaults to building for MIPS64, the main MIPS Makefile ends up using the short-form -<arch> flags in cflags-y. This is because the calls to cc-option always fail to use the long-form -march=<arch> flag due to the lack of an -mabi=<abi> flag in KBUILD_CFLAGS at the point where the cc-option function is executed. The resulting GCC invocation is something like: $ mips64-linux-gcc -Werror -march=mips32r2 -c -x c /dev/null -o tmp cc1: error: '-march=mips32r2' is not compatible with the selected ABI These short-form -<arch> flags are dropped by the VDSO Makefile's filtering, and so we attempt to build the VDSO without specifying any architecture. This results in an attempt to build the VDSO using whatever the compiler's default architecture is, regardless of whether that is suitable for the kernel configuration. One encountered build failure resulting from this mismatch is a rejection of the sync instruction if the kernel is configured for a MIPS32 or MIPS64 r1 or r2 target but the toolchain defaults to an older architecture revision such as MIPS1 which did not include the sync instruction: CC arch/mips/vdso/gettimeofday.o /tmp/ccGQKoOj.s: Assembler messages: /tmp/ccGQKoOj.s:273: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:329: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:520: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:714: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:1009: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:1066: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:1114: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:1279: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:1334: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:1374: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:1459: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:1514: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:1814: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:2002: Error: opcode not supported on this processor: mips1 (mips1) `sync' /tmp/ccGQKoOj.s:2066: Error: opcode not supported on this processor: mips1 (mips1) `sync' make[2]: *** [scripts/Makefile.build:318: arch/mips/vdso/gettimeofday.o] Error 1 make[1]: *** [scripts/Makefile.build:558: arch/mips/vdso] Error 2 make[1]: *** Waiting for unfinished jobs.... This can be reproduced for example by attempting to build pistachio_defconfig using Arnd's GCC 8.1.0 mips64 toolchain from kernel.org: https://mirrors.edge.kernel.org/pub/tools/crosstool/files/bin/x86_64/8.1.0/… Resolve this problem by using the long-form -march=<arch> in all cases, which makes it through the arch/mips/vdso/Makefile's filtering & is thus consistently used to build both the kernel proper & the VDSO. The use of cc-option to prefer the long-form & fall back to the short-form flags makes no sense since the short-form is just an abbreviation for the also-supported long-form in all GCC versions that we support building with. This means there is no case in which we have to use the short-form -<arch> flags, so we can simply remove them. The manual redefinition of _MIPS_ISA is removed naturally along with the use of the short-form flags that it accompanied, and whilst here we remove the separate assembler ISA selection. I suspect that both of these were only required due to the mips32 vs mips2 mismatch that was introduced by commit 59b3e8e9aac6 ("[MIPS] Makefile crapectomy.") and fixed but not cleaned up by commit 9200c0b2a07c ("[MIPS] Fix Makefile bugs for MIPS32/MIPS64 R1 and R2."). I've marked this for backport as far as v4.4 where the MIPS VDSO was introduced. In earlier kernels there should be no ill effect to using the short-form flags.
