[PATCH v2 3/5] perf probe: Fix some error exit paths
From: Arnaldo Carvalho de Melo <acme(a)redhat.com> That could leave filedescriptors open and leak memory. Also stop using xmalloc, use malloc and handle results just like other error cases in the same routine that used it.

[PATCH 5/5] perf tools: remove xstrndup, xmalloc, xzalloc
From: Arnaldo Carvalho de Melo <acme(a)redhat.com> All the functions that call this can handle the equivalent, non panic'ing wrapped routines.

[PATCH v2 4/5] perf probe: Don't call die()
From: Arnaldo Carvalho de Melo <acme(a)redhat.com> Functions that were calling xzalloc also returned -1 when, for other reasons, it could fail, and the calleds are coping with failures, so stop using die() and xzalloc().

[PATCH 25/25] kdb,debug_core: Allow the debug core to receive a panic notification
It is highly desirable to trap into kdb on panic. The debug core will attempt to register as the first in line for the panic notifier.

[PATCH 3/7] x86,kgdb: Implement early hardware breakpoint debugging
It is not possible to use the hw_breakpoint.c API prior to mm_init(), but it is possible to use hardware breakpoints with the kernel debugger. Prior to smp_init() it is possible to simply write to the dr registers of the boot cpu directly. This can be used up until the kgdb_arch_late() is invoked, at which poin... 18 May 2010 22:31
