Currently we unconditionally issue a flush from xfs_free_buftarg, but
since 2.6.29-rc1 this gives a warning in the style ofend_request: I/O error, dev vdb, sector 0

The inode can't be locked by anyone else as we just created it a few
lines above and it's not been added to any lookup data structure yet.So use a trylock that must succeed to get around the lockdep warnings.

Andras Korn reported an oops on log replay causes by a corrupted
xfs_inode_log_format_t passing a 0 size to kmem_zalloc. This patch handles
to small or too large numbers of log regions gracefully by rejecting the
log replay with a useful error message.Signed-off-by: Christoph Hellwig

The host really shouldn't be notifying us of config changes
before the device status is VIRTIO_CONFIG_S_DRIVER or
VIRTIO_CONFIG_S_DRIVER_OK.However, if we do happen to be interrupted while we're not
attached to a driver, we really shouldn't oops. Prevent
this simply by checking that device->driver is non-NULL
before trying to notify the driver of config changes.Problem observed by doing a "set_link virtio.0 down" with
QEMU before the net driver had been loaded.Signed-off-by: Mark McLoughlin

Current refcounting for modules (done if CONFIG_MODULE_UNLOAD=y) is
using a lot of memory.Each 'struct module' contains an [NR_CPUS] array of full cache lines.
This patch uses existing infrastructure (percpu_modalloc() &
percpu_modfree()) to allocate percpu space for the refcount storage.Instead of wasting NR_CPUS*128 bytes (on i386), we now use
nr_cpu_ids*sizeof(local_t) bytes.On a typical distro, where NR_CPUS=8, shiping 2000 modules, we reduce
size of module files by about 2 Mbytes. (1Kb per module)Instead of having all refcounters in the same memory node - with TLB misses
because of vmalloc() - this new implementation permits to have better
NUMA properties, since each CPU will use storage on its preferred node,
thanks to percpu storage.Signed-off-by: Eric Dumazet

With the PXA270 MMC hardware, there seems to be an issue of
data corruption on writes where a 4KB data block is offset
by one byte.If we delay enabling the DMA for writes until after the CMD/RESP

This patch adds support for the ST Microelectronics version of
the PL180 PrimeCell. They use designer ID 0x80 and have a few
alterations/bugfixes related to open drain and HW flow control.
They also add some SDIO registers, I am unsure if these are
in ST HW only or if this is things also added in later ARM
revisions, but they are included in the mmci.h file for
completeness.Signed-off-by: Linus Walleij

This patch adds a MX2/MX3 specific SDHC driver. The hardware is basically
the same as in the MX1, but unlike the MX1 controller the MX2
controller just works as expected. Since the MX1 driver has more
workarounds for bugs than anything else I had no success with supporting
MX1 and MX2 in a sane way in one driver.Signed-off-by: Sascha Hauer

This is a port of libata's pata_cs5536.c (written by Martin K. Petersen)
to IDE subsystem.Changes done while at it:
* Reprogram PIO/MWDMA timings if needed before and after DMA transfer
(chipset uses shared PIO/MWDMA timings).* Fix cable detection to report 80-wires cable if BIOS set it for any
device on a port (IDE core will do drive-side cable detection later).* Don't disable UDMA while programming PIO timings.
* Simplify PCI/MSR support.
Pros of having IDE host driver in addition to libata's one:
* IDE is much lighter than SCSI+libata, the host driver itself is also
a bit smaller:text data bss dec hex filename
1261 496 4 1761 6e1 drivers/ata/pata_cs5536.o
1242 128 4 1374 55e drivers/ide/cs5536.o* This allows use of IDE features which are unavailable under libata.
v2:
* Fixes per review from Sergei:
- simplify dependency check in Kconfig
- use IDE_DRV_MASK also for ->drive_data
- disable UDMA when programming MWDMA
- program new DTC timings only when necessary
- fix printk() level in cs5536_init_one()* Fix patch description according to comments from Alan and Sergei.

Since the complete re-write in 2.6.10, some PowerMacs (At least PowerMac 5500
and PowerMac G3 Beige rev A) with ATI Mach64 chip have suffered from unstable
columns in their framebuffer image. This seems to depend on a value (4) read
from PLL_EXT_CNTL register, which leads to incorrect DSP config parameters to
be written to the chip. This patch uses a value calculated by aty_init_pll_ct
instead, as a starting point.There are questions as to whether this should be extended to other platforms
or maybe made dependent on specific chip types, but in the meantime, this has
been tested on various powermacs and works for them so let's commit it.Signed-off-by: Risto Suominen
