Merge tag 'metag-for-v3.15-2' of git://git.kernel.org/pub/scm/linux/kernel/git/jhogan/metag
Pull Metag architecture and related fixes from James Hogan:
"Mostly fixes for metag and parisc relating to upgrowing stacks.
- Fix missing compiler barriers in metag memory barriers.
- Fix BUG_ON on metag when RLIMIT_STACK hard limit is increased
beyond safe value.
- Make maximum stack size configurable. This reduces the default
user stack size back to 80MB (especially on parisc after their
removal of _STK_LIM_MAX override). This only affects metag and
parisc.
- Remove metag _STK_LIM_MAX override to match other arches and follow
parisc, now that it is safe to do so (due to the BUG_ON fix
mentioned above).
- Finally now that both metag and parisc _STK_LIM_MAX overrides have
been removed, it makes sense to remove _STK_LIM_MAX altogether"
* tag 'metag-for-v3.15-2' of git://git.kernel.org/pub/scm/linux/kernel/git/jhogan/metag:
asm-generic: remove _STK_LIM_MAX
metag: Remove _STK_LIM_MAX override
parisc,metag: Do not hardcode maximum userspace stack size
metag: Reduce maximum stack size to 256MB
metag: fix memory barriers
