15 years agoomap_hsmmc: Allow for a shared VccQ
Adrian Hunter [Tue, 2 Feb 2010 02:51:25 +0000 (18:51 -0800)]
omap_hsmmc: Allow for a shared VccQ

EMMC can have two voltage supplies, Vcc and VccQ
which are implemented in the code as consumer
supplies vmmc and vmmc_aux.

If the regulator that supplies vmmc_aux is shared
with other consumers, then sending it to sleep
will disrupt those consumers.  However, the
TWL4030-family regulators may have OFF remapped
to SLEEP, in which case 'regulator_disable()'
will put the regulator to sleep only when all
consumers are disabled - which is the desired
behaviour.

This patch adds a platform data field to allow
that option.

15 years agomm: fix migratetype bug which slowed swapping
Hugh Dickins [Fri, 29 Jan 2010 17:46:34 +0000 (17:46 +0000)]
mm: fix migratetype bug which slowed swapping

After memory pressure has forced it to dip into the reserves, 2.6.32's
5f8dcc21211a3d4e3a7a5ca366b469fb88117f61 "page-allocator: split per-cpu
list into one-list-per-migrate-type" has been returning MIGRATE_RESERVE
pages to the MIGRATE_MOVABLE free_list: in some sense depleting reserves.

Fix that in the most straightforward way (which, considering the overheads
of alternative approaches, is Mel's preference): the right migratetype is
already in page_private(page), but free_pcppages_bulk() wasn't using it.

How did this bug show up?  As a 20% slowdown in my tmpfs loop kbuild
swapping tests, on PowerMac G5 with SLUB allocator.  Bisecting to that
commit was easy, but explaining the magnitude of the slowdown not easy.

The same effect appears, but much less markedly, with SLAB, and even
less markedly on other machines (the PowerMac divides into fewer zones
than x86, I think that may be a factor).  We guess that lumpy reclaim
of short-lived high-order pages is implicated in some way, and probably
this bug has been tickling a poor decision somewhere in page reclaim.

But instrumentation hasn't told me much, I've run out of time and
imagination to determine exactly what's going on, and shouldn't hold up
the fix any longer: it's valid, and might even fix other misbehaviours.

15 years agoSplit 'flush_old_exec' into two functions
Linus Torvalds [Fri, 29 Jan 2010 06:14:42 +0000 (22:14 -0800)]
Split 'flush_old_exec' into two functions

'flush_old_exec()' is the point of no return when doing an execve(), and
it is pretty badly misnamed.  It doesn't just flush the old executable
environment, it also starts up the new one.

Which is very inconvenient for things like setting up the new
personality, because we want the new personality to affect the starting
of the new environment, but at the same time we do _not_ want the new
personality to take effect if flushing the old one fails.

As a result, the x86-64 '32-bit' personality is actually done using this
insane "I'm going to change the ABI, but I haven't done it yet" bit
(TIF_ABI_PENDING), with SET_PERSONALITY() not actually setting the
personality, but just the "pending" bit, so that "flush_thread()" can do
the actual personality magic.

This patch in no way changes any of that insanity, but it does split the
'flush_old_exec()' function up into a preparatory part that can fail
(still called flush_old_exec()), and a new part that will actually set
up the new exec environment (setup_new_exec()).  All callers are changed
to trivially comply with the new world order.
