perf dwarf: Fix potential array out of bounds access

2015-09-01T14:33:48Z

There is a problem in the dwarf-regs.c files for sh, sparc and x86 where it is possible to make an out-of-bounds array access when searching for register names. This patch fixes it by replacing '<=' to '<', so when register (number == XXX_MAX_REGS), get_arch_regstr() will return NULL.

perf tools: Fix build on non-glibc systems due to libio.h absence

2013-03-15T16:05:13Z

Including libio.h causes build failures on uClibc systems (which lack libio.h). It appears that libio.h was only included to pull in a definition for NULL, so it has been replaced by stddef.h. On powerpc, libio.h was conditionally included, but could be removed completely as it is unneeded. Also, the included of stdlib.h was changed to stddef.h (as again, only NULL is needed).
