With the recent reorg of the io scheduler selection, it unfortunately
became possible to select an io scheduler to be the default even if it
wasn't builtin. Fix this by requiring the default scheduler to be
builtin.

This fixes the x86-64 find_[first|next]_zero_bit() function for the

Cannot build XFS filesystem support as module with quota support.  It
works only when the XFS filesystem support is compiled into the kernel.
Menuconfig prevents from setting CONFIG_XFS_FS=m and CONFIG_XFS_QUOTA=y.

How to reproduce: configure the XFS filesystem with quota support as
module.  The resulting kernel won't have quota support compiled into
xfs.ko.

Fix: Changing the fs/xfs/Kconfig file from tristate to bool lets you
configure the quota support to be compiled into the XFS module.  The
Makefile-linux-2.6 checks only for CONFIG_XFS_QUOTA=y.

[ARM] 3083/1: include/asm-arm/arch-ixp4xx/io.h: eliminate warnings for pointer passed to integral function argument

Patch from John Bowler

Fix for a compiler warning, this wasn't apparent in 2.6.12, I
believe the compiler options have been changed (somewhere) so
that passing a (void*) to a (u32) argument is now warned.

This accounts for the majority of the warnings in my builds of
the 2.6.14 kernel for NSLU2.

The patch changes pointer parameters declared as u32 to be
declared as either, for read parameters:

const volatile void __iomem *

and for write parameters:

volatile void __iomem *

cfq's add_req_fn callback may invoke q->request_fn directly and
depending on low-level driver used and timing, a queued request may be
finished & deallocated before add_req_fn callback returns.  So,
__elv_add_request must not access rq after it's passed to add_req_fn
callback.

This patch moves rq_mergeable test above add_req_fn().  This may
result in q->last_merge pointing to REQ_NOMERGE request if add_req_fn
callback sets it but as RQ_NOMERGE is checked again when blk layer
actually tries to merge requests, this does not cause any problem.
