X-Git-Tag: v2.6.36-rc1~559^2~47^2~3 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e3e94084adb5610987283367574ebc771e8206e1;p=pandora-kernel.git powerpc, hw_breakpoint: Discard extraneous interrupt due to accesses outside symbol length Many a times, the requested breakpoint length can be less than the fixed breakpoint length i.e. 8 bytes supported by PowerPC 64-bit server (Book III S) processors. This could lead to extraneous interrupts resulting in false breakpoint notifications. This detects and discards such interrupts for non-ptrace requests. We don't change ptrace behaviour to avoid breaking compatability. [Suggestion from Paul Mackerras to add a new flag in 'struct arch_hw_breakpoint' to identify extraneous interrupts] Signed-off-by: K.Prasad Signed-off-by: Paul Mackerras --- Reading git-diff-tree failed
