mm: add comment about deprecation of __GFP_NOFAIL

2010-03-06T19:26:27+00:00

__GFP_NOFAIL was deprecated in dab48dab, so add a comment that no new
users should be added.

mm/pm: force GFP_NOIO during suspend/hibernation and resume

2010-03-06T19:26:26+00:00

There are quite a few GFP_KERNEL memory allocations made during
suspend/hibernation and resume that may cause the system to hang, because
the I/O operations they depend on cannot be completed due to the
underlying devices being suspended.

Avoid this problem by clearing the __GFP_IO and __GFP_FS bits in
gfp_allowed_mask before suspend/hibernation and restoring the original
values of these bits in gfp_allowed_mask durig the subsequent resume.

mm: remove free_hot_page()

2010-03-06T19:26:25+00:00

free_hot_page() is just a wrapper around free_hot_cold_page() with
parameter 'cold = 0'.  After adding a clear comment for
free_hot_cold_page(), it is reasonable to remove a level of call.

BUILD_BUG_ON(): fix it and a couple of bogus uses of it

2009-09-23T14:39:29+00:00

gcc permitting variable length arrays makes the current construct used for
BUILD_BUG_ON() useless, as that doesn't produce any diagnostic if the
controlling expression isn't really constant.  Instead, this patch makes
it so that a bit field gets used here.  Consequently, those uses where the
condition isn't really constant now also need fixing.

Note that in the gfp.h, kmemcheck.h, and virtio_config.h cases
MAYBE_BUILD_BUG_ON() really just serves documentation purposes - even if
the expression is compile time constant (__builtin_constant_p() yields
true), the array is still deemed of variable length by gcc, and hence the
whole expression doesn't have the intended effect.

mm: Extend gfp masking to the page allocator

2009-06-18T20:12:57+00:00

The page allocator also needs the masking of gfp flags during boot,
so this moves it out of slab/slub and uses it with the page allocator
as well.
