Modules: ES18xx driver

Second of 4 es18xx.c patches culminating in Zoom Video support.

This patch changes the 'record source' mux routines to reflect the fact
that not all of the
supported chipsets have 8 possible inputs. Some have 4 and some have 5.

Testing:
This work was initially done on the source from the Debian Sarge ALSA
package, then tested
on an ES1879 and an ES1878 machine. Patches were created against the
Sarge code and then edited
to apply correctly to the ALSA cvs code. Lastly the patched ALSA cvs
code was test for
successful compilation. No additional testing was done on the ALSA cvs
version.

Modules: ES18xx driver

First of 4 es18xx.c patches culminating in Zoom Video support.
While adding support for Zoom Video to the es18xx driver I found some of
the mixer controls
were wrong. Since you guys went to the trouble of supplying the
datasheets for the supported
chipsets I did a review of all of them and tried to get es18xx.c to
accurately reflect the
proper mixer controls for each chipset. If the datasheets are wrong then
so are my patches.

This first patch moves some controls from the common-to-all-chipsets array
'snd_es18xx_base_controls' to a chipset-specific array and adds code to
manage that new array.
Also while testing on my ES1878 test machine I discovered it needed a
couple of udelays in
the identify function so those are in this patch as well.

Modules: USB generic driver

This is my naive attempt at adding ALSA device support. The attached
patch provides support for the EDIROL UM-3ex. This is a 3-port USB midi
interface with a built-in USB hub and the ability to chain 2 other
UM-3x's in a master-slave configuration. I only have one, so I do not
know how this works in practice.

Though this is a 3-port device, I had to throw in that 4th 'Control' interface
to the definition in order to make the 3rd port work. If I set in/out_cables
to 0x000b, a 3rd interface appears on the driver, but it does nothing.
Changing it to 0x000f allows the 3rd interface to work, but of course
interface 4 does not work because it does not exist.

We only need to write an invalid tag every 16 bytes,
so taking advantage of this can save many instructions
compared to the simple memset() call we make now.

A prefetching implementation is implemented for sun4u
and a block-init store version if implemented for Niagara.

The next trick is to be able to perform an init and
a copy_tsb() in parallel when growing a TSB table.

Currently allocations are very constrained for 32-bit processes.
It grows down-up from 0x70000000 to 0xf0000000 which gives about
2GB of stack + dynamic mmap() space.

So support the top-down method, and we need to override the
generic helper function in order to deal with D-cache coloring.

With these changes I was able to squeeze out a mmap() just over
3.6GB in size in a 32-bit process.

This is good for up to %50 performance improvement of some test cases.
The problem has been the race conditions, and hopefully I've plugged
them all up here.

1) There was a serious race in switch_mm() wrt. lazy TLB
   switching to and from kernel threads.

   We could erroneously skip a tsb_context_switch() and thus
   use a stale TSB across a TSB grow event.

   There is a big comment now in that function describing
   exactly how it can happen.

2) All code paths that do something with the TSB need to be
   guarded with the mm->context.lock spinlock.  This makes
   page table flushing paths properly synchronize with both
   TSB growing and TLB context changes.

3) TSB growing events are moved to the end of successful fault
   processing.  Previously it was in update_mmu_cache() but
   that is deadlock prone.  At the end of do_sparc64_fault()
   we hold no spinlocks that could deadlock the TSB grow
   sequence.  We also have dropped the address space semaphore.

While we're here, add prefetching to the copy_tsb() routine
and put it in assembler into the tsb.S file.  This piece of
code is quite time critical.

There are some small negative side effects to this code which
can be improved upon.  In particular we grab the mm->context.lock
even for the tsb insert done by update_mmu_cache() now and that's
a bit excessive.  We can get rid of that locking, and the same
lock taking in flush_tsb_user(), by disabling PSTATE_IE around
the whole operation including the capturing of the tsb pointer
and tsb_nentries value.  That would work because anyone growing
the TSB won't free up the old TSB until all cpus respond to the
TSB change cross call.

I'm not quite so confident in that optimization to put it in
right now, but eventually we might be able to and the description
is here for reference.

This code seems very solid now.  It passes several parallel GCC
bootstrap builds, and our favorite "nut cruncher" stress test which is
a full "make -j8192" build of a "make allmodconfig" kernel.  That puts
about 256 processes on each cpu's run queue, makes lots of process cpu
migrations occur, causes lots of page table and TLB flushing activity,
incurs many context version number changes, and it swaps the machine
real far out to disk even though there is 16GB of ram on this test
system. :-)
