Enforce access rules where appropriate.
If the compiler is smart enough, this may buy us an optimization or two
as a side effect.

This is needed for full AMD and VIA drivers and possibly more. Functions
to turn actual clocking and cycle timings into register values. Also to
merge shared timings to compute an optimal timing set.

sata_qstor strays into a nasty area - gcc handling of wide enums is
full of bugs that got fixed between gcc versions creating portability
nightmare. Single-member enums are safe, so are ones that stay within
the range of int or unsigned int. Anything beyond that is asking for
trouble.
Declaration of constants split in two enums, taking the ~0UL one into
a separate enum.

In drivers/acpi/glue.c the address of an integer is cast to the address of
an unsigned long. This breaks on systems where a long is larger than an
int --- for a start the int can be misaligned; for a second the assignment
through the pointer will overwrite part of the next variable.

I've gotten a report on lkml, of a possible regression in the MGA DRM in
2.6.14-rc4 (since -rc1), I haven't been able to reproduce it here, but I've
figured out some possible issues in the mga code that were definitely
wrong, some of these are from DRM CVS, the main fix is the agp enable bit
on the old code path still used by everyone.....

The main problem fixes is that in certain situations stopping md arrays may
take longer than you expect, or may require multiple attempts. This would
only happen when resync/recovery is happening.
This patch fixes three vaguely related bugs.
1/ The recent change to use kthreads got the setting of the
process name wrong. This fixes it.
2/ The recent change to use kthreads lost the ability for
md threads to be signalled with SIG_KILL. This restores that.
3/ There is a long standing bug in that if:
- An array needs recovery (onto a hot-spare) and
- The recovery is being blocked because some other array being
recovered shares a physical device and
- The recovery thread is killed with SIG_KILL
Then the recovery will appear to have completed with no IO being
done, which can cause data corruption.
This patch makes sure that incomplete recovery will be treated as
incomplete.
Note that any kernel affected by bug 2 will not suffer the problem of bug
3, as the signal can never be delivered. Thus the current 2.6.14-rc
kernels are not susceptible to data corruption. Note also that if arrays
are shutdown (with "mdadm -S" or "raidstop") then the problem doesn't
occur. It only happens if a SIGKILL is independently delivered as done by
'init' when shutting down.

Changes all spinlocks that can be held during an irq handler to disable
interrupts while the lock is held. Changes spin_[un]lock_irq to use the
irqsave/irqrestore variants for robustness and readability.
In raw1394.c:handle_iso_listen(), don't grab host_info_lock at all -- we're
not accessing host_info_list or host_count, and holding this lock while
trying to tasklet_kill the iso tasklet this can cause an ABBA deadlock if
ohci:dma_rcv_tasklet is running and tries to grab host_info_lock in
raw1394.c:receive_iso. Test program attached reliably deadlocks all SMP
machines I have been able to test without this patch.

This is a (final?) hack to support the odd DMA allocation requirements
of the b44 hardware. The b44 hardware has a 30-bit DMA mask. On x86,
anything less than a 32-bit DMA mask forces allocations into the 16MB
GFP_DMA range. The memory there is somewhat limited, often resulting
in an inability to initialize the b44 driver.
This hack uses streaming DMA allocation APIs in order to provide an
alternative in case the GFP_DMA allocation fails. It is somewhat ugly,
but not much worse than the similar existing hacks to support SKB
allocations in the same driver. FWIW, I have received positive
feedback on this from several Fedora users.

Get rid of the mdelay call in rhine_disable_linkmon. The function
is called from the via-rhine versions of mdio_read and mdio_write.
Those functions are indirectly called from rhine_check_media and
rhine_tx_timeout, both of which can be called in interrupt context.
So, create tx_timeout_task and check_media_task as instances of struct
work_struct inside of rhine_private. Then, change rhine_tx_timeout to
invoke schedule_work for tx_timeout_task (i.e. rhine_tx_timeout_task),
moving the work to process context. Also, change rhine_error (invoked
from rhine_interrupt) to invoke schedule_work for check_media_task
(i.e. rhine_check_media_task), which simply calls rhine_check media
in process context. Finally, add a call to flush_scheduled_work in
rhine_close to avoid any resource conflicts with pending work items.
