[PATCH 0/5] hw_breakpoints: Fix racy ptrace breakpoint acccesses

[Frederic Weisbecker <fweisbec@gmail.com>]

I should have fixed that a few month ago but got sidetracked.
Please have a look at this. x86 and powerpc already had support
for breakpoints before so it fixes a regression there (cf stable tag)
For the others it only a fix.

Other archs than x86 have been only compile tested.

Thanks.
