[PATCH 0/2] x86: separating entry text section + kprobes fix

From: Jiri Olsa
Date: Mon Feb 21 2011 - 09:25:42 EST


hi,

while fixing the optimized kprobes issue, we found out that separating
the entry text section might have performance benefits with regards to
the instruction cache usage.

attached patches:
1/2 - x86: separating entry text section
2/2 - kprobes: disabling optimized kprobes for entry text section

wbr,
jirka
