Currently we have a maze of configuration variables that determine the
maximum slab size. Worst of all it seems to vary between SLAB and SLUB.So define a common maximum size for kmalloc. For conveniences sake we use
the maximum size ever supported which is 32 MB. We limit the maximum size
to a lower limit if MAX_ORDER does not allow such large allocations.For many architectures this patch will have the effect of adding large
kmalloc sizes. x86_64 adds 5 new kmalloc sizes. So a small amount of
memory will be needed for these caches (contemporary SLAB has dynamically
sizeable node and cpu structure so the waste is less than in the past)Most architectures will then be able to allocate object with sizes up to
MAX_ORDER. We have had repeated breakage (in fact whenever we doubled the
number of supported processors) on IA64 because one or the other struct
grew beyond what the slab allocators supported. This will avoid future
issues and f.e. avoid fixes for 2k and 4k cpu support.CONFIG_LARGE_ALLOCS is no longer necessary so drop it.
It fixes sparc64 with SLAB.

Consolidate functionality into the #ifdef section.
Extract tracing into one subroutine.
Move object debug processing into the #ifdef section so that the
code in __slab_alloc and __slab_free becomes minimal.Reduce number of functions we need to provide stubs for in the !SLUB_DEBUG case.

The atomicity when handling flags in SLUB is not necessary since both flags
used by SLUB are not updated in a racy way. Flag updates are either done
during slab creation or destruction or under slab_lock. Some of these flags
do not have the non atomic variants that we need. So define our own.Signed-off-by: Christoph Lameter

I'm getting zillions of undefined references to __kmalloc_size_too_large on
alpha. For some reason alpha is building out-of-line copies of kmalloc_slab()
into lots of compilation units.It turns out that gcc just isn't smart enough to work out that
__builtin_contant_p(size)==true implies that __builtin_contant_p(index)==true.So let's give it a bit of help.

There is no user of destructors left. There is no reason why we should keep
checking for destructors calls in the slab allocators.The RFC for this patch was discussed at
http://marc.info/?l=linux-kernel&m=117882364330705&w=2Destructors were mainly used for list management which required them to take a
spinlock. Taking a spinlock in a destructor is a bit risky since the slab
allocators may run the destructors anytime they decide a slab is no longer
needed.Patch drops destructor support. Any attempt to use a destructor will BUG().

In commit e3c7db621bed4afb8e231cb005057f2feb5db557 we fixed the resume
ordering, so that the ACPI low-level resume code was called before the
actual driver resume was called. However, that broke the nesting logic
of suspend and resume, and we continued to suspend the devices _after_
we the ACPI device suspend code was called.That resulted in us saving PCI state for devices that had already been
changed by ACPI, and in some cases disabled entirely (causing the PCI
save_state to be all-ones). Which in turn caused the wrong state to be
written back on resume.This moves the ACPI device suspend to after the device model per-device
suspend() calls. This fixes the bogus state save.Thanks to Lukáš Hejtmánek for testing.

This patch fixes a bug whereby AC97 bus device data was being clobbered
when AC97 codecs using the generic ac97_codec.c driver were being
registered. Codecs that didn't use the generic driver were unaffected
(e.g. WM9712, WM9713).
Changes:-
o Add new AC97 codec class for custom (or need bus dev registration)
AC97 codecs.
o Only register/deregister this custom codec device with the AC97 bus.
The generic AC97 driver already does this for generic codec devices.
This may be related to bug #3038 :-

Our assumption that most distros issue STANDBYNOW seems wrong. The
upstream sysvinit and thus many distros including gentoo and opensuse
don't take any action for libata disks on spindown. We can skip
compat handling for these distros so that they don't need to update
anything to take advantage of kernel-side shutdown.Signed-off-by: Tejun Heo

Unlocking ap->lock and ssleeping don't work because SCSI commands can
be issued from completion path without context. Reimplement delayed
completion by allowing translation functions to override
qc->scsidone(), storing the original completion function to
scmd->scsi_done() and overriding qc->scsidone() with a function which
schedules delayed invocation of scmd->scsi_done().This isn't pretty at all but all the ugly parts are thankfully
contained in the stop translation path where the compat feature is
implemented.Signed-off-by: Tejun Heo

Whether a controller needs IDE or SATA ACPI hierarchy is determined by
the programming interface of the controller not by whether the
controller is SATA or PATA, or it supports slave device or not. This
patch adds ATA_FLAG_ACPI_SATA port flags which tells libata-acpi that
the port needs SATA ACPI nodes, and sets the flag for ahci and
sata_sil24.Signed-off-by: Tejun Heo

Device might be resized during ata_dev_configure() due to HPA or
(later) ACPI _GTF. Currently it's worked around by caching n_sectors
before turning off HPA. The cached original size is overwritten if
the device is reconfigured without being hardreset - which always
happens after configuring trasnfer mode. If the device gets hardreset
for some reason after that, revalidation fails with -ENODEV.This patch makes size checking more robust by moving n_sectors check
from ata_dev_reread_id() to ata_dev_revalidate() after the device is
fully configured. No matter what happens during configuration, a
device must have the same n_sectors after fully configured to be
treated as the same device.Signed-off-by: Tejun Heo
