2016-07-26perf s390: Fix 'start' address of module's mapSong Shan Gong4-0/+30
At present, when creating module's map, perf gets 'start' address by parsing '/proc/modules', but it's the module base address, it isn't the start address of the '.text' section. In most arches, it's OK. But for s390, it places 'GOT' and 'PLT' relocations before '.text' section. So there exists an offset between module base address and '.text' section, which will incur wrong symbol resolution for modules. Fix this bug by getting 'start' address of module's map from parsing '/sys/module/[module name]/sections/.text', not from '/proc/modules'.

git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux Pull s390 updates from Martin Schwidefsky: "There are a couple of new things for s390 with this merge request: - a new scheduling domain "drawer" is added to reflect the unusual topology found on z13 machines. Performance tests showed up to 8 percent gain with the additional domain. - the new crc-32 checksum crypto module uses the vector-galois-field multiply and sum SIMD instruction to speed up crc-32 and crc-32c. - proper __ro_after_init support, this requires RO_AFTER_INIT_DATA in the generic vmlinux.lds linker script definitions. - kcov instrumentation support. A prerequisite for that is the inline assembly basic block cleanup, which is the reason for the net/iucv/iucv.c change. - support for 2GB pages is added to the hugetlbfs backend. Then there are two removals: - the oprofile hardware sampling support is dead code and is removed. The oprofile user space uses the perf interface nowadays. - the ETR clock synchronization is removed, this has been superseeded be the STP clock synchronization.

That patch also needed a fix for 32 bit builds and both were reverted in one go. - Al Viro noticed that a fix for a leak in an error path was not valid with the given API and provided a better fix, so the original patch was reverted.

2016-07-26x86/microcode/intel: Fix initrd loading with CONFIG_RANDOMIZE_MEMORY=yBorislav Petkov1-2/+14
CONFIG_RANDOMIZE_MEMORY=y randomizes the physical memmap and thus the address where the initrd is located. Therefore, we need to add the offset KASLR put us to in order to find the initrd again on the AP path. In the future, we will get rid of the initrd address caching and query the address on both the BSP and AP paths but that would need more work.

2016-07-26selftests/powerpc: exec() with suspended transactionCyril Bur5-18/+98
Perform an exec() class syscall with a suspended transaction. This is a test for the bug we fixed in 8e96a87c5431 ("powerpc/tm: Always reclaim in start_thread() for exec() class syscalls").

2016-07-26powerpc: Improve comment explaining why we modify VRSAVEAnton Blanchard1-4/+5
The comment explaining why we modify VRSAVE is misleading, glibc does rely on the behaviour. Update the comment. Signed-off-by: Anton Blanchard <[email protected]> Reviewed-by: Cyril Bur <[email protected]> Signed-off-by: Michael Ellerman <[email protected]>
2016-07-26powerpc/mm: Drop unused externs for hpte_init_beat[_v3]()Michael Ellerman1-2/+0
We removed the BEAT support in 2015 in commit bf4981a00636 ("powerpc: Remove the celleb support"). These externs are unused since then. Signed-off-by: Michael Ellerman <[email protected]>
2016-07-26powerpc/mm: Rename hpte_init_lpar() and move the fallback to a headerMichael Ellerman3-8/+8
hpte_init_lpar() is part of the pseries platform, so name it as such. Move the fallback implementation for when PSERIES=n into the header, dropping the weak implementation. The panic() is now handled by the calling code. Signed-off-by: Michael Ellerman <[email protected]>
2016-07-26powerpc/mm: Fix build break when PPC_NATIVE=nMichael Ellerman1-1/+4
The recent commit to rework the hash MMU setup broke the build when CONFIG_PPC_NATIVE=n. Fix it by adding an IS_ENABLED() check before calling hpte_init_native(). Removing the else clause opens the possibility that we don't set any ops, which would probably lead to a strange crash later. So add a check that we correctly initialised at least one member of the struct.
