To support multiple TC microthreads acting as "CPUs" within a VPE,
VPE-wide interrupt mask bits must be specially manipulated during
interrupt handling. To support legacy drivers and interrupt controller
management code, SMTC has a "backstop" to track and if necessary restore
the interrupt mask. This has some performance impact on interrupt service
overhead. Disable it only if you know what you are doing.

Since the number of dma channels varies between pxa25x and pxa27x, it
introduces some specific code in dma.c. This patch moves the specific
code to pxa25x.c and pxa27x.c and makes dma.c more generic.
1. add pxa_init_dma() for dma initialization, the number of channels
are passed in by the argument
2. add a "prio" field to the "struct pxa_dma_channel" for the channel
priority, and is initialized in pxa_init_dma()
3. use a general priority comparison with the channels "prio" field so
to remove the processor specific pxa_for_each_dma_prio macro, this
is not lightning fast as the original one, but it is acceptable as
it happens when requesting dma, which is usually not so performance
critical

Instead of all drivers reading pci config space to get the revision

This exposes some issues where drivers where reading a word or a dword
for the revision number, and adding useless error-handling around the
read. Some drivers even just read it for no purpose of all.
In devices where the revision ID is being copied over and used in what
appears to be the equivalent of hotpath, I have left the copy code

Linux does not gracefully deal with multiple processors going
through OS_MCA aa part of the same MCA event. The first cpu
into OS_MCA grabs the ia64_mca_serialize lock. Subsequent
cpus wait for that lock, preventing them from reporting in as
rendezvoused. The first cpu waits 5 seconds then complains
that all the cpus have not rendezvoused. The first cpu then
handles its MCA and frees up all the rendezvoused cpus and
releases the ia64_mca_serialize lock. One of the subsequent
cpus going thought OS_MCA then gets the ia64_mca_serialize
lock, waits another 5 seconds and then complains that none of
the other cpus have rendezvoused.
This patch allows multiple CPUs to gracefully go through OS_MCA.
The first CPU into ia64_mca_handler() grabs a mca_count lock.
Subsequent CPUs into ia64_mca_handler() are added to a list of cpus
that need to go through OS_MCA (a bit set in mca_cpu), and report
in as rendezvoused, and but spin waiting their turn.
The first CPU sees everyone rendezvous, handles his MCA, wakes up
one of the other CPUs waiting to process their MCA (by clearing
one mca_cpu bit), and then waits for the other cpus to complete
their MCA handling. The next CPU handles his MCA and the process
repeats until all the CPUs have handled their MCA. When the last
CPU has handled it's MCA, it sets monarch_cpu to -1, releasing all
the CPUs.
In testing this works more reliably and faster.
