Special note about sys_arm_sync_file_range(), which is implemented as:
asmlinkage long sys_arm_sync_file_range(int fd, unsigned int flags,
loff_t offset, loff_t nbytes)
{
return sys_sync_file_range(fd, offset, nbytes, flags);
}
We can't export sys_sync_file_range() directly on ARM because the
argument list someone picked does not fit in the available registers.

new syscalls before they hit the kernel.

[PATCH] pata_via: Cable detect error
[PATCH] Fix help text for CONFIG_ATA_PIIX
[PATCH] initializer entry defined twice in pata_rz1000
[PATCH] ata: fix platform_device_register_simple() error check
[PATCH] ahci: do not mangle saved HOST_CAP while resetting controller
[PATCH] libata: don't initialize sg in ata_exec_internal() if DMA_NONE (take #2)

[libata] use kmap_atomic(KM_IRQ0) in SCSI simulator
[PATCH] ata_piix: use piix_host_stop() in ich_pata_ops
[PATCH] ata_piix: IDE mode SATA patch for Intel ICH9
On architectures where the atomicity of the bit operations is handled by
external means (ie a separate spinlock to protect concurrent accesses),
just doing a direct assignment on the workqueue data field (as done by
commit 4594bf159f) can cause the
assignment to be lost due to lack of serialization with the bitops on
the same word.
So we need to serialize the assignment with the locks on those
architectures (notably older ARM chips, PA-RISC and sparc32).
So rather than using an "unsigned long", let's use "atomic_long_t",
which already has a safe assignment operation (atomic_long_set()) on
such architectures.
This requires that the atomic operations use the same atomicity locks as
the bit operations do, but that is largely the case anyway. Sparc32
will probably need fixing.
Architectures (including modern ARM with LL/SC) that implement sane
atomic operations for SMP won't see any of this matter.

Doug Chapman noticed that mincore() will doa "copy_to_user()" of the
result while holding the mmap semaphore for reading, which is a big
no-no. While a recursive read-lock on a semaphore in the case of a page
fault happens to work, we don't actually allow them due to deadlock
schenarios with writers due to fairness issues.
Doug and Marcel sent in a patch to fix it, but I decided to just rewrite
the mess instead - not just fixing the locking problem, but making the
code smaller and (imho) much easier to understand.

The UDMA66 VIA hardware has no controller side cable detect bits we can
use. This patch minimally fixes the problem by reporting unknown in this
case and using drive side detection.
The old drivers/ide code does some additional tricks but those aren't
appropriate now we are in -rc.
Without this update UDMA66 via controllers run slowly. They don't fail so
it's a borderline call whether this is -rc material or not.

Reboot hangs on LPARs without diag308 support. The reason for this is,
that before the reboot is done, the channel subsystem is shut down.
During the reset on each possible subchannel a "store subchannel" is
done. This operation can end in a program check interruption, if the
specified subchannel set is not implemented by the hardware. During
the reset, currently we do not have a program check handler, which
leads to the described kernel bug. We install now a new program check
handler for the reboot code to fix this problem.

Currently in SCTP, we maintain a local address list by rebuilding the whole

This patch fixes it by only adding/deleting the address for which we
receive the event.
Also removed the sctp_local_addr_lock() which is no longer needed as we
now use list_for_each_safe() to traverse this list. This fixes the bugs
in sctp_copy_laddrs_xxx() routines where we do copy_to_user() while
