Impact: fix crash on x86/UV
UV is the SGI "UltraViolet" machine, which is x86_64 based.
BAU is the "Broadcast Assist Unit", used for TLB shootdown in UV.
This patch removes the allocation and initialization of an unused table.
This table is left over from a development test mode. It is unused in
the present code.
And it was incorrectly initialized: 8 entries allocated but 17 initialized,
causing slab corruption.
This patch should go into 2.6.27 and 2.6.28 as well as the current tree.
Diffed against 2.6.28 (linux-next, 12/30/08)

The pda rework (commit 3461b0af025251bbc6b3d56c821c6ac2de6f7209)
to remove static boot cpu pdas introduced a performance bug.
_boot_cpu_pda is the actual pda used by the boot cpu and is definitely
not "__read_mostly" and ended up polluting the read mostly section with
writes. This bug caused regression of about 8-10% on certain syscall
intensive workloads.

This makes the top-level function just allocate a single pc entry, and then
pass it down as a pointer to all the helper functions that also need one
of those "struct ide_atapi_pc" things. As far as I can tell, the use of
these things never overlaps each other, BUT I DID NOT CHECK VERY CLOSELY!
So I'm not guaranteeing this is correct, and I don't have the hardware. It
would be good for somebody who knows the code more, and has the hardware,
could please test this?
With this, ide-floppy still has fairly big stack usage, but instead of
idefloppy_ioctl [vmlinux]: 1208
ide_floppy_get_capacity [vmlinux]: 872
idefloppy_release [vmlinux]: 408
idefloppy_open [vmlinux]: 408
where those two first ones are at the very top of the list of stack users
for me, it's now
ide_floppy_get_capacity [vmlinux]: 404
ide_floppy_ioctl [vmlinux]: 364
ie they are still high, but they are no longer at the top.
Borislav: Since ide_floppy_get_capacity is passed as a function pointer to other
parts of the kernel (e.g., block layer) we need that ide_atapi_pc to be created
on stack. Also, redid stack users numbers above. The two functions missing from
Linus' original 'make stackusage' output are due to ide being
rewritten/reorganized atm.

* Move hack for flush requests from choose_drive() to do_ide_request().
* Add ide_plug_device() helper and convert core IDE code from using
per-hwgroup lock as a request lock to use the ->queue_lock instead.
* Remove no longer needed:
- choose_drive() function
- WAKEUP() macro
- 'sleeping' flag from ide_hwif_t
- 'service_{start,time}' fields from ide_drive_t
This patch results in much simpler and more maintainable code
(besides being a scalability improvement).
v2:
* Fixes/improvements based on review from Elias:
- take as many requests off the queue as possible
- remove now redundant BUG_ON()

* Tell the block layer that we are not done handling requests by using
blk_plug_device() in ide_do_request() (request handling function)
and ide_timer_expiry() (timeout handler) if the queue is not empty.
* Remove optimization which directly calls ide_do_request() for the next
queued command from the ide_intr() (IRQ handler) and ide_timer_expiry().
* Remove no longer needed IRQ masking from ide_do_request() - in case of
IDE ports needing serialization disable_irq_nosync()/enable_irq() was
used for the (possibly shared) IRQ of the other IDE port.
* Put the misplaced comment in the right place in ide_do_request().
* Drop no longer needed 'int masked_irq' argument from ide_do_request().
* Merge ide_do_request() into do_ide_request().
* Remove no longer needed IDE_NO_IRQ define.
While at it:
* Don't use HWGROUP() macro in do_ide_request().
* Use __func__ in ide_intr().
This patch reduces IRQ hadling latency for IDE and improves the system-wide
handling of shared IRQs (which should result in more timeout resistant and
stable IDE systems). It also makes it possible to do some further changes
later (i.e. replace some busy-waiting delays with sleeping equivalents).
v2:
Changes per review from Elias Oltmanns:
- fix wrong goto statement in 'if (startstop == ide_stopped)' block
- use spin_unlock_irq()
- don't use obsolete HWIF() macro

Impact: cleanup
This compiler warning:
arch/x86/mm/init_32.c:515: warning: unused variable 'pgd_base'
triggers because permanent_kmaps_init() is a CPP macro in the
!CONFIG_HIGHMEM case, that does not tell the compiler that the
'pgd_base' parameter is used.
Convert permanent_kmaps_init() (and set_highmem_pages_init()) to
C inline functions - which gives the parameter a proper type and
which gets rid of the compiler warning as well.

This set of patches introduces calls to the following set of functions:
usb_endpoint_dir_in(epd)
usb_endpoint_dir_out(epd)
usb_endpoint_is_bulk_in(epd)
usb_endpoint_is_bulk_out(epd)
usb_endpoint_is_int_in(epd)
usb_endpoint_is_int_out(epd)
usb_endpoint_num(epd)
usb_endpoint_type(epd)
usb_endpoint_xfer_bulk(epd)
usb_endpoint_xfer_control(epd)
usb_endpoint_xfer_int(epd)
usb_endpoint_xfer_isoc(epd)
In some cases, introducing one of these functions is not possible, and it
just replaces an explicit integer value by one of the following constants:
USB_ENDPOINT_XFER_BULK
USB_ENDPOINT_XFER_CONTROL
USB_ENDPOINT_XFER_INT
USB_ENDPOINT_XFER_ISOC

Impact: extra safety checks during transition
When CONFIG_CPUMASKS_OFFSTACK is set, the new cpumask_ operators only
use bits up to nr_cpu_ids, not NR_CPUS. Using the old cpus_ operators
on these masks can mean accessing undefined bits.
After some discussion, Mike and I decided to err on the side of caution;
we zero the "undefined" bits in alloc_cpumask_var_node() until all the
old cpumask functions are removed.

Mainly changing cpumask_t to 'struct cpumask' and similar simple API

2) Use cpumask_var_t in taskstats_user_cmd().
