X-Git-Tag: v2.6.34-rc6~83^2~4 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=035df35d968323f6f463c8789553e8589efcbcd4;p=pandora-kernel.git sparc64: Allocate sufficient stack space in ftrace stubs. 128 bytes is sufficient for the register window save area, but the calling conventions allow the callee to save up to 6 incoming argument registers into the stack frame after the register window save area. This means a minimal stack frame is 176 bytes (128 + (6 * 8)). This fixes random crashes when using the function tracer. Reported-by: Frederic Weisbecker Signed-off-by: David S.
