If the kernel attempts to execute a CP1 or CP2 instruction and it
aborts, and a FP emulator is not loaded, we try to return as if to
a user context, instead of the proper kernel context. Since the
fault came from kernel mode, we must use the kernel return paths.

This fix was already merged in commit 96f9c2e277768099479fbed7c3b69c294b1fadef
but reverted in commit 989316ddfeafd0e8fb51a4d811383769ad62637a. After
stresstesting we found that the fix does not add new regressions and
works around a TX hang spotted by several users.

pdflush hit the BUG_ON(!PageSlab(page)) in kmem_freepages called from
fallback_alloc: cache_grow already freed those pages when alloc_slabmgmt
failed. But it wouldn't have freed them if __GFP_NO_GROW, so make sure
fallback_alloc doesn't waste its time on that case.
