Hi Linus,
Please pull the following metag / parisc fixes, mostly relating to upgrowing
stacks. These changes only affect metag and parisc, and although the
asm-generic one isn't strictly a fix it's simple and follows naturally from
the other _STK_LIM_MAX override removals (here for metag and in rc4 for
parisc).
Thanks
James

asm-generic: remove _STK_LIM_MAX (2014-05-15 00:32:09 +0100)
----------------------------------------------------------------
Metag architecture and related fixes for v3.15
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.
