amd64_edac: Do not report error overflow as a separate error
MCE, AMD: Limit MCE decoding to current families for now
When the Overflow MCi_STATUS bit is set, EDAC reports the lost error
with a "no information available" message which often puzzles users
parsing the dmesg. This doesn't make much sense since this error has
been lost anyway so no need for reporting it separately. Thus, report
the overflow bit setting in the MCE dump instead. While at it, remove
reporting of MiscV and ErrorEnable (en) which are superfluous.
Now it looks like this:
[ 1501.650024] MC4_STATUS: Corrected error, other errors lost: yes, CPU context corrupt: no, CECC Error
[ 1501.666887] Northbridge Error, node 2

Remove harmful BUG_ON() from ata_bmdma_qc_issue(),
as it casts too wide of a net and breaks sata_mv.
It also crashes the kernel while doing the BUG_ON().
There's already a WARN_ON_ONCE() further down to catch
the case of POLLING for a BMDMA operation.

Fix DSM/TRIM commands in sata_mv (v2).
These need to be issued using old-school "BM DMA",
rather than via the EDMA host queue.
Since the chips don't have proper BM DMA status,
we need to be more careful with setting the ATA_DMA_INTR bit,
since DSM/TRIM often has a long delay between "DMA complete"
and "command complete".
GEN_I chips don't have BM DMA, so no TRIM for them.

Commit 8bf0223ed515be24de0c671eedaff49e78bebc9c (hwmon, k8temp: Fix
temperature reporting for ASB1 processor revisions) fixed temperature
reporting for ASB1 CPUs. But those CPU models (model 0x6b, 0x6f, 0x7f)
were packaged both as AM2 (desktop) and ASB1 (mobile). Thus the commit
leads to wrong temperature reporting for AM2 CPU parts.
The solution is to determine the package type for models 0x6b, 0x6f,
0x7f.
This is done using BrandId from CPUID Fn8000_0001_EBX[15:0]. See
"Constructing the processor Name String" in "Revision Guide for AMD
NPT Family 0Fh Processors" (Rev. 3.46).

When converting this to the new wait_for macro I inverted the wait
condition, which causes all sorts of problems. So correct it to fix
several failures caused by the bad wait (flickering, bad output
detection, tearing, etc.).

Xen events are logically edge triggered, as Xen only calls the event
upcall when an event is newly set, but not continuously as it remains set.
As a result, use handle_edge_irq rather than handle_level_irq.
This has the important side-effect of fixing a long-standing bug of
events getting lost if:
- an event's interrupt handler is running
- the event is migrated to a different vcpu
- the event is re-triggered
The most noticable symptom of these lost events is occasional lockups
of blkfront.
Many thanks to Tom Kopec and Daniel Stodden in tracking this down.

IPIs and VIRQs are inherently per-cpu event types, so treat them as such:
- use a specific percpu irq_chip implementation, and
- handle them with handle_percpu_irq
This makes the path for delivering these interrupts more efficient
(no masking/unmasking, no locks), and it avoid problems with attempts
to migrate them.
