55cab290fc Revert my ata_identify()/ata_reinit() related changes: r189166, r189091
and partially r188903. Revert breaks new drives detection on reinit to the
state as it was before me, but fixes series of new bugs reported by some
people.

Unconditional queueing of ata_completed() calls can lead to deadlock if
due to timeout ata_reinit() was called at the same thread by previous
ata_completed(). Calling of ata_identify() on ata_reinit() in current
implementation opens numerous races and deadlocks.

Problems I was touching here are still exist and should be addresed, but
probably in different way.

bb22735cfd Remove direct ata_completed() call options from ata_finish(), except for the
kernel dumping case.

ata_completed() may initiate ata_reinit() on error, that may lead to drives
attach or detach. Attach and detach are sending requests to drives and sleep
waiting for results. But ata_finish() can be called directly from
interrupt handler where sleeping is prohibited, so we must break this chain
somewhere. This place seems to fit best.

b11f9dd52a Go back to preallocating everything possible on init.
This avoids calling busdma in the request processing path which caused a traumatic performance degradation.
Allocation has be postponed to after we know how many devices we possible can have on portmulitpliers to save some space.

The problem is that the PM support is part of a much larger WIP here, but due to popular demand I decided to get some of it imported.

int64_t's is safe all over, and doesn't pullute the code.

52c5335529 Update the ICH7 support so it deals better with chips without AHCI.
Update Intel MatrixRAID support to be able to pick up RAID0+1 (RAID10)
and RAID5 arrays without panic'ing.
This has the side effect of now also supporting multiple volumes on
MatrixRAID's now I have the metadata better understood..

be4f357149 Normalize a significant number of kernel malloc type names:
- Prefer '_' to ' ', as it results in more easily parsed results in
  memory monitoring tools such as vmstat.

- Remove punctuation that is incompatible with using memory type names
  as file names, such as '/' characters.

- Disambiguate some collisions by adding subsystem prefixes to some
  memory types.

- Generally prefer lower case to upper case.

- If the same type is defined in multiple architecture directories,
  attempt to use the same name in additional cases.

Not all instances were caught in this change, so more work is required to
finish this conversion.  Similar changes are required for UMA zone names.

4729e22704 Avoid GCC optimizations from injecting a call to memset(?) in order
to initialize the buffer array in ata_raid_attach() by removing the
initializer. There's no memset(?) in the kernel. Instead, assign
'\0' to the first element. The buffer array holds strings only, so
this is functionally equivalent.
