This arch-independent routine copies data to a memory-mapped I/O region,
using 32-bit accesses. The naming is double-underscored to make it clear
that it does not guarantee write ordering, nor does it perform a memory
barrier afterwards; the kernel doc also explicitly states this. This style
of access is required by some devices.This change also introduces include/linux/io.h, at Andrew's suggestion. It
only has one occupant at the moment, but is a logical destination for
oft-replicated contents of include/asm-*/{io,iomap}.h to migrate to.Signed-off-by: Bryan O'Sullivan

Clean up the interface to hrtimers by changing the init code to pass the mode
as well as the clock. This allow the init code to select the correct base and
eliminates extra timer re-init code in posix-timers. We also simplify the

From: Steven Rostedtrostedt@goodmis.org
CPU0 expires a posix-timer and runs the callback function. The signal is
queued.After releasing the posix-timer lock and before returning to hrtimer_run_queue
CPU0 gets interrupted. CPU1 delivers the queued signal and rearms the timer.
CPU0 comes back to hrtimer_run_queue and sets the timer state to expired.The next modification of the timer can result in an oops, because the state
information is wrong.Keep track of state = RUNNING and check if the state has been in the return
path of hrtimer_run_queue. In case the state has been changed, ignore a
restart request and do not touch the state variable.Signed-off-by: Steven Rostedt

At the 2.6.12 timeframe ipmi_si_intf.c was patched to provide default
register spacings in try_init_acpi() if the register spacing was set to
zero, similar to code in other routines.Unfortunately, another patch was simultaneously added that exits early from
try_init_acpi() if the register spacings are set to zero, circumventing the
new defaults. This patch removes the early exit code and some incorrect
comments that aren't present in other common code snippets.Signed-off-by: Rocky Craig

Reduce substantially the amount of code using PF_MEMALLOC, as envisaged in the

Clean up the code responsible for the on-disk mirror logs by using the
set_le_bit test_le_bit functions of ext2. That makes the BE machines keep the
bitmap internally in LE order - it does mean you can't use any other type of
operations on the bitmap words but that looks to be OK in this instance. The
efficiency tradeoff is very minimal as you would expect for something that
ext2 uses.This allows us to remove bits_to_core(), bits_to_disk() and log->disk_bits.
Also increment the mirror log disk version transparently to avoid sharing with
older kernels that suffered from the 64-bit BE bug.Signed-off-by: Patrick Caulfield

Kernel 2.6.16-rc1 broke the ide-scsi driver: ide-scsi loads but fails to
find any devices to bind to. It also triggers a message "Driver 'ide-scsi'
needs updating - please use bus_type methods" from the driver core.The IDE core in 2.6.16-rc1 changed the location of an IDE driver's
->probe()/->remove()/->shutdown() methods: they are now in the ide_driver_t
struct not in the gen_driver sub-struct. drivers/ide/ was updated for this
change but ide-scsi.c wasn't. Hence the breakage.This patch repairs ide-scsi and also eliminates the driver core warning.

While asynchronous reads mean a performance improvement in most cases, if
the filesystem assumed that reads are synchronous, then async reads may
degrade performance (filesystem may receive reads out of order, which can
confuse it's own readahead logic).With sshfs a 1.5 to 4 times slowdown can be measured.
There's also a need for userspace filesystems to know whether asynchronous
reads are supported by the kernel or not.To achive these, negotiate in the INIT request whether async reads will be
used and the maximum readahead value. Update interface version to 7.6If userspace uses a version earlier than 7.6, then disable async reads, and
set maximum readahead value to the maximum read size, as done in previous
versions.Signed-off-by: Miklos Szeredi
