X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0203f4433664945428198bd614bb35213b258892;p=pandora-kernel.git

kprobes/x86: Blacklist indirect thunk functions for kprobes

commit c1804a236894ecc942da7dc6c5abe209e56cba93 upstream.

Mark __x86_indirect_thunk_* functions as blacklist for kprobes
because those functions can be called from anywhere in the kernel
including blacklist functions of kprobes.

[bwh: Backported to 3.2: We don't have _ASM_NOKPROBE etc., so add indirect
 thunks to the built-in blacklist]
