[PATCH] Kprobes blacklist: Conditionally add x86-specific symbols

From: oskar.andero
Date: Thu Mar 07 2013 - 05:44:38 EST


From: Björn Davidsson <bjorn.davidsson@xxxxxxxxxxxxxx>

The kprobes blacklist contains x86-specific symbols.
Looking for these in kallsyms takes unnecessary time
during startup on non-X86 platform.
Added #ifdef CONFIG_X86 around them.
