Slab allocators: define common size limitations
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.

spinlock. Taking a spinlock in a destructor is a bit risky since the slab

Fix ACPI suspend / device suspend ordering problem
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.

libata: during revalidation, check n_sectors after device is configured
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.

[SPARC64]: Add hypervisor API negotiation and fix console bugs.
Hypervisor interfaces need to be negotiated in order to use
some API calls reliably. So add a small set of interfaces
to request API versions and query current settings.
This allows us to fix some bugs in the hypervisor console:
1) If we can negotiate API group CORE of at least major 1
minor 1 we can use con_read and con_write which can improve
console performance quite a bit.
2) When we do a console write request, we should hold the
spinlock around the whole request, not a byte at a time.
What would happen is that it's easy for output from
different cpus to get mixed with each other.
3) Use consistent udelay() based polling, udelay(1) each
loop with a limit of 1000 polls to handle stuck hypervisor
console.

sis5513: PIO mode setup fixes
* limit max PIO mode to PIO4, this driver doesn't support PIO5 and attempt
to program PIO5 by config_art_rwp_pio() could result in incorrect PIO
timings being programmed and possibly the data corruption (for < ATA100
family chipsets PIO0 timings were used, for ATA100 and ATA100a - the random
content of test1 variable was used, for ATA133 - MWDMA0 timings were used)
* BUG() in sis5513_tune_chipset() if somebody tries to force unsupported PIO5,
also cleanup this function a bit while at it
* add comment about PIO0 timings for < ATA100 family chipsets
* remove open-coded best PIO mode selection from config_art_rwp_pio(),
it contained numerous bugs:
- it didn't check for validity of id->eide_pio_modes and id->eide_pio_iordy
before using them
- it tried to found out maximum PIO mode basing on minimum IORDY cycle time
(moreover wrong cycle times were used for PIO1/5)
- it was overriding PIO blacklist and conservative PIO "downgrade" done
by ide_get_best_pio_mode()
* use sis5513_tune_drive() instead of config_art_rwp_pio()
in sis5513_config_xfer_rate() so the correct PIO mode is also set
on drive even if the device is not IORDY/DMA capable
* config_art_rwp_pio() was always setting the best possible mode and not
the wanted one - fix it and move ide_get_best_pio_mode() call to
config_chipset_for_pio()
* don't use ide_find_best_mode() in config_chipset_for_pio(), it was being
overriden by config_art_rwp_pio() for the host timings anyway + we need to
set the same PIO mode on the device and the host
* pass correct "pio" argument (255 instead of 5) to sis5513_tune_drive() call
in sis5513_config_xfer_rate() so the best PIO mode is set on the drive
and not PIO4

pdc202xx_old: rewrite mode programming code (v2)
This patch is based on the documentation (I would like to thank Promise
for it) and also partially on the older vendor driver.
Rewrite mode programming code:
* disable 66MHz clock in pdc202xx_tune_chipset() so it is correctly disabled
even if both devices on the channel are not DMA capable and after reset
* enable/disable IORDY and PREFETCH bits in pdc202xx_tune_chipset()
as they need to be setup correctly also for PIO only devices, plus IORDY
wasn't disabled for non-IORDY devices and PREFETCH wasn't disabled for
ATAPI devices
* remove dead code for setting SYNC_ERDDY_EN bits from config_chipset_for_dma()
(driver sets ->autotune to 1 so PIO modes are always programmed => lower
nibble of register A never equals 4 => "chipset_is_set" is always true)
* enable PIO mode programming for all ATAPI devices
(it was limited to ->media == ide_cdrom devices)
* remove extra reads of registers A/B/C, don't read register D et all
* do clearing / programming of registers A/B/C in one go
(gets rid of extra PCI config space read/write cycle)
* set initial values of drive_conf/AP/BP/CP variables to zero
(paranoia for the case when PCI reads fail)
* remove XFER_UDMA6 to XFER_UDMA5 remapping case - it can't happen
(ide_rate_filter() takes care of it)
* fix XFER_MW_DMA0 timings (they were overclocked, use the official ones)
* fix bitmasks for clearing bits of register B:
- when programming DMA mode bit 0x10 of register B was cleared which
resulted in overclocked PIO timing setting (iff PIO0 was used)
- when programming PIO mode bits 0x18 weren't cleared so suboptimal
timings were used for PIO1-4 if PIO0 was previously set (bit 0x10)
and for PIO0/3/4 if PIO1/2 was previously set (bit 0x08)
* add FIXME comment about missing locking for 66MHz clock register
Also while at it:
* remove unused defines
* do a few cosmetic / CodingStyle fixes
* bump driver version
v2:
* in pdc202xx_tune_chipset() the old content of drive configuration
registers is used only by the debugging code so cover "drive_conf"
PCI registers read by #if PDC202XX_DEBUG_DRIVE_INFO

ucc_geth: eliminate max-speed, change interface-type to phy-connection-type
It was agreed that phy-connection-type was a better name for
the interface-type property, so this patch renames it.
Also, the max-speed property name was determined too generic,
and is therefore eliminated in favour of phy-connection-type
derivation logic.
