2014-11-19perf tools: Only print base source file for srclineAndi Kleen
For perf report with --sort srcline only print the base source file name. This makes the results generally fit much better to the screen. The path is usually not that useful anyways because it is often from different systems.

2014-11-19perf tools: Fix annotation with kcoreAdrian Hunter
Patch "perf tools: Fix build-id matching on vmlinux" breaks annotation with kcore. The problem is that symbol__annotate() first gets the filename based on the build-id which was previously not set. This patch provides a quick fix, however there should probably be only one way to determine the filename. e.g. symbol__annotate() should use the same way as dso__data_fd().

2014-11-19perf symbols: Fallback to kallsyms when using the minimal 'ELF' loaderArnaldo Carvalho de Melo
The minimal ELF loader should not return 1 when it manages to read the vmlinux build-id, it should instead return 0, meaning that it hasn't loaded any symbols, since it doesn't parses ELF at all. That way, the main symbol.c routines will understand that it is necessary to continue looking for a file with symbols, and when no libelf is linked, that means it will eventually try kallsyms.

Patch 09a5723983 ("arm64: Use include/asm-generic/io.h") correctly removed the GENERIC_IOMAP selection from ARM64, which is not needed on architectures that have memory-mapped PCI I/O space, however we now lack a pci_iomap() function.

2014-11-19clockevent: sun4i: Fix race condition in the probe codeMaxime Ripard
The interrupts were activated and the handler registered before the clockevent was registered in the probe function. The interrupt handler, however, was making the assumption that the clockevent device was registered. That could cause a null pointer dereference if the timer interrupt was firing during this narrow window. Fix that by moving the clockevent registration before the interrupt is enabled.

2014-11-19sparc: io: remove duplicate relaxed accessors on sparc32Arnd Bergmann
Commit 1191ccb34cf8 ("sparc: io: implement dummy relaxed accessor macros for writes") added the relaxed accessors (readl_relaxed etc) in a file that is shared between sparc32 and sparc64. However, the earlier e1039fb42609 ("sparc32: introduce asm-generic/io.h") had already changed the sparc32 implementation to use asm-generic/io.h, which provides the same macros, resulting in lots of build errors. This moves the definitions from the shared sparc file into the sparc64-only file to fix the sparc32 build regression.

2014-11-18mac80211: minstrel_ht: fix a crash in rate sortingFelix Fietkau
The commit 5935839ad73583781b8bbe8d91412f6826e218a4 "mac80211: improve minstrel_ht rate sorting by throughput & probability" introduced a crash on rate sorting that occurs when the rate added to the sorting array is faster than all the previous rates. Due to an off-by-one error, it reads the rate index from tp_list[-1], which contains uninitialized stack garbage, and then uses the resulting index for accessing the group rate stats, leading to a crash if the garbage value is big enough.
