Move duplicate and functionally equivalent code for accessing registers
and stack (CONFIG_HAVE_REGS_AND_STACK_ACCESS_API) from arch subdirs into
common kernel files.

I'm sending this out again (with updated distribution list) because v2
just never got pulled in, even though I don't think there were any
outstanding issues.

A big cross arch patch like this would often get taken by Andrew Morton, but
AFAICS you didn't CC him - so I just added him, perhaps he'll pick it up for
us :D

The other problem is that the second patch is commingling changes to 6 separate
architectures:

16 files changed, 106 insertions(+), 343 deletions(-)

that should probably be 6 separate patches. Easier to review, easier to bisect to,
easier to revert, etc.

Thanks,

Ingo


I see your point but I'm not sure it could have been broken into separate successive patches that would each build for all architectures.
