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 <[email protected]> to add a new flag in
'struct arch_hw_breakpoint' to identify extraneous interrupts]
