- driver receives many null TS packets (pid=0x1fff).  They occupy the
  limited USB bandwidth and this leads to loss of video packets.  Enabling the
  null packet filter fixes this.

- packets that flexcop sends to USB have a 2 byte header that has to be
  removed.

- sometimes a TS packet is split between different urbs.  These parts have
  to be combined in a temporary buffer.

This patch should fix the avc_alloc_node() oom condition that Andrew
reported when no policy is loaded in SELinux.

Prior to this patch, when no policy was loaded, the SELinux "security
server" (policy engine) was only returning allowed decisions for the
requested permissions for each access check.  This caused the cache to
thrash when trying to use SELinux for real work with no policy loaded
(typically, the no policy loaded state is only for bootstrapping to the
point where we can load an initial policy).

This patch changes the SELinux security server to return the complete
allowed access vector at once, and then to reset the cache after the
initial policy load to flush the initial cache state created during
bootstrapping.

If block_read_full_page() detects an error when running get_block() it will
run SetPageError(), then it will zero out the block in pagecache and will mark
the buffer_head uptodate.

So at the end of readahead we end up with a non-uptodate pagecache page which
is marked PageError.  But it has uptodate buffers.

The pagefault code will run ClearPageError, will launch readpage a second time
and block_read_full_page() will notice the uptodate buffers and will mark the
page uptodate as well.  We end up with an uptodate, !PageError page full of
zeros and the error is lost.

(It seems a little odd that filemap_nopage() runs ClearPageError().  I guess
all of this adds up to meaning that for each attempted access to the page, the
pagefault handler will retry the I/O.  Which is good and bad.  If the app is
ignoring SIGBUS for some reason we could get a lot of back-to-back I/O
errors.)

Fix it by not marking the pagecache buffer_head as uptodate if the attempt to
map that buffer to a disk block failed.

On my IA64 machine, after kernel 2.6.12-rc3 boots, an edge-triggered
interrupt (IRQ 46) keeps triggered over and over again.  There is no IRQ 46
interrupt action handler.  It has lots of impact on performance.

Kernel 2.6.10 and its prior versions have no the problem.  Basically,
kernel 2.6.10 will mask the spurious edge interrupt if the interrupt is
triggered for the second time and its status includes
IRQ_DISABLE|IRQ_PENDING.

Originally, IA64 kernel has its own specific _irq_desc definitions in file
arch/ia64/kernel/irq.c.  The definition initiates _irq_desc[irq].status to
IRQ_DISABLE.  Since kernel 2.6.11, it was moved to architecture independent
codes, i.e.  kernel/irq/handle.c, but kernel/irq/handle.c initiates
_irq_desc[irq].status to 0 instead of IRQ_DISABLE.

I found a bug in the packet writing driver that could cause data
corruption.  The problem arised if the driver got a write request for a
sector in a "zone" it was already working on.  In that case it was supposed
to queue the write request until it was done processing earlier requests
for the same zone, and instead work on some other zone in the mean time.
However, if there was no other zone to work on, the driver would initiate
two packet_data objects for the same zone, causing unpredictable things to
happen.

This patch removes the assumption that LAPIC entries contain the BSP as its
first entry.  This is a slight improvement to the temporary fix submitted by
Suresh Siddha.

- Removes assumption that LAPIC entries contain BSP first.

- Builds x86_acpiid_to_apicid[] and bios_cpu_apicid[] properly with BSP as
  first entry.

- Made maxcpus=1 boot on these systems.  Since the parsing earlier in
  arch/x86_64/kernel/mpparse.c stopped after maxcpus entries, other entries
  were not processed, this causes kernel not to boot on these systems.

TBD: x86_acpiid_to_apicid and bios_cpu_apicid[] seem to be exactly the
     same.  This could be removed, but might need more work to cleanup.
