i2c-nforce2: Abort the transaction on error
This patch is to add an abort function that will bring back the MCP51/55
controller if it was blocked by a block-read operation, in particular.
(When a slave sends a wrong byte count on a byte read, the host gets
locked up). I've only tested it on an MCP51 and MCP55. However, I'm
almost certain it will also work on MCP65, I just did not have the board
to test it on. Thus for now the abort function will only be called
if an MCP51/55 was detected.

Use ide_config_drive_speed() instead of pmac_ide_do_setfeature() and remove

Since for IDE PMAC host driver IDE_CONTROL_REG is always true, device's

the only changes in behavior are:
* if PIO mode is set then ->dma_off_queitly is called to disable DMA
* if setting transfer mode fails ide_dump_status() is called to dump status
v2:
* IDE PMAC controllers allow separate PIO and DMA timings and PPC userland
depends on this fact, and calls "hdparm -p" without calling "hdparm -d".
Therefore to compensate for DMA being disabled by ide_config_drive_speed()

- add IDE_HFLAG_SET_PIO_MODE_KEEP_DMA flag and set it in PMAC host driver

[MTD] [NAND] Blackfin on-chip NAND Flash Controller driver
This is the driver for latest Blackfin on-chip nand flash controller
- use nand_chip and mtd_info common nand driver interface
- provide both PIO and dma operation
- compiled with ezkit bf548 configuration
- use hardware 1-bit ECC
- tested with YAFFS2 and can mount YAFFS2 filesystem as rootfs
ChangeLog from try#1
- use hweight32() instead of count_bits()
- replace bf54x with bf5xx and BF54X with BF5XX
- compare against plat->page_size in 2 cases when enable hardware ECC
ChangeLog from try#2
- passed nand_test suites
- use cpu_relax() instead of busy wait loop
- some coding style issue pointed out by Andrew

[MTD] [NOR] fix ctrl-alt-del can't reboot for intel flash bug
When we press ctrl-alt-del,kernel_restart_prepare will invoke
cfi_intelext_reboot which will set flash to read array mode, but later
when device_shutdown is invoked which may put current work queue to
sleep and other process may be scheduled to running and programming
flash in not FL_READY mode again. So we can't boot up if this flash is
used for bootloader.

until the flash became full. Don't Do That.

[JFFS2] Relax threshold for triggering GC due to dirty blocks.
Instead of matching resv_blocks_gcmerge, which is only about 3, instead
match resv_blocks_gctrigger, which includes a proportion of the total

KVM: Skip pio instruction when it is emulated, not executed
If we defer updating rip until pio instructions are executed, we have a
problem with reset: a pio reset updates rip, and when the instruction

Fix by updating rip when we see decode the instruction, not after emulation.
