X-Git-Tag: v2.6.29-rc1~313
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=129415607845d4daea11ddcba706005c69dcb942;p=pandora-kernel.git

kprobes: add kprobe_insn_mutex and cleanup arch_remove_kprobe()

Add kprobe_insn_mutex for protecting kprobe_insn_pages hlist, and remove
kprobe_mutex from architecture dependent code.

This allows us to call arch_remove_kprobe() (and free_insn_slot) while
holding kprobe_mutex.
