Allocate space from the highest-address PCI bus resource first, then work
downward.
Previously, we looked for space in PCI host bridge windows in the order
we discovered the windows. For example, given the following windows
(discovered via an ACPI _CRS method):
pci_root PNP0A03:00: host bridge window [mem 0x000a0000-0x000bffff]
pci_root PNP0A03:00: host bridge window [mem 0x000c0000-0x000effff]
pci_root PNP0A03:00: host bridge window [mem 0x000f0000-0x000fffff]
pci_root PNP0A03:00: host bridge window [mem 0xbff00000-0xf7ffffff]
pci_root PNP0A03:00: host bridge window [mem 0xff980000-0xff980fff]
pci_root PNP0A03:00: host bridge window [mem 0xff97c000-0xff97ffff]
pci_root PNP0A03:00: host bridge window [mem 0xfed20000-0xfed9ffff]
we attempted to allocate from [mem 0x000a0000-0x000bffff] first, then
[mem 0x000c0000-0x000effff], and so on.
With this patch, we allocate from [mem 0xff980000-0xff980fff] first, then
[mem 0xff97c000-0xff97ffff], [mem 0xfed20000-0xfed9ffff], etc.
Allocating top-down follows Windows practice, so we're less likely to
trip over BIOS defects in the _CRS description.
On the machine above (a Dell T3500), the [mem 0xbff00000-0xbfffffff] region
doesn't actually work and is likely a BIOS defect. The symptom is that we
move the AHCI controller to 0xbff00000, which leads to "Boot has failed,
sleeping forever," a BUG in ahci_stop_engine(), or some other boot failure.

The tg3 driver calls device_set_wakeup_enable() under spin_lock_bh,
which causes a problem to happen after the recent core power
management changes, because this function can sleep now. Fix this
by moving the device_set_wakeup_enable() call out of the
spin_lock_bh-protected area.

8f6205cd572fece673da0255d74843680f67f879 introduced a bug where a
timed out DMA request is never requeued and lost.
6072f7491f5ef391a575e18a1165e72a3eef1601 fixed this by making
ide_dma_timeout_retry() requeue the request itself. While the fix is
correct, it makes DMA and non-DMA paths asymmetric regarding how the
in flight request is requeued.
As long as hwif->rq is set, the IDE driver is assuming ownership of
the request and the request should either be completed or requeued
when clearing hwif->rq. In the timeout path, the ide driver holds
onto the request as long as the recovery action (ie. reset) is in
progress and clears it after the state machine is stopped (ide_stopped
return), so the existing requeueing logic is correct. The bug
occurred because ide_dma_timeout_retry() explicitly clears hwif->rq
without requeueing it.
ide_dma_timeout_retry() is called only by ide_timer_expiry() and
returns ide_started only when ide_error() would return it - ie. after
reset state machine has started in which case the state machine will
eventually end up executing the ide_stopped path in ide_timer_expiry()
after reset protocol is complete. So, there is no need to clear
hwif->rq from ide_dma_timeout_retry(). ide_timer_expiry() will handle
it the same way as PIO timeout path.
Kill hwif->rq clearing and requeueing from ide_dma_timeout_retry() and
let ide_timer_expiry() deal with it. The end result should remain the
same.
grepping shows ide_dma_timeout_retry() is the only site which clears
hwif->rq without taking care of the request, so there shouldn't be
similar fallouts.

blk_mark_rq_complete. If qla4xxx_cmd_wait is then called
from qla4xxx_eh_host_reset, we will always fail, because if
the driver calls scsi_done then the the block layer will fail
at blk_complete_request's blk_mark_rq_complete call instead of
calling the normal completion path including the function,
blk_queue_end_tag, which releases the tag.

This patch adds the Scatter-Gather (sg) API to libosd.
Scatter-gather enables a write/read of multiple none-contiguous
areas of an object, in a single call. The extents may overlap
and/or be in any order.
The Scatter-Gather list is sent to the target in what is called
a "cdb continuation segment". This is yet another possible segment
in the osd-out-buffer. It is unlike all other segments in that it
sits before the actual "data" segment (which until now was always
first), and that it is signed by itself and not part of the data
buffer. This is because the cdb-continuation-segment is considered
a spill-over of the CDB data, and is therefor signed under
OSD_SEC_CAPKEY and higher.
TODO: A new osd_finalize_request_ex version should be supplied so
the @caps received on the network also contains a size parameter
and can be spilled over into the "cdb continuation segment".
Thanks to John Chandy <john.chandy@uconn.edu> for the original
code, and investigations. And the implementation of SG support
in the osd-target.

Added driver logic to detect the last devloss timeout of remote nodes which
was still in use of FCF. At that point, the driver should set the last
in-use remote node devloss timeout flag if it was not already set and should
perform proper action on the in-use FCF and recover of FCF from firmware,
depending on the state the driver's FIP engine is in.
Find eligible FCF through FCF table rescan or the next new FCF event when
FCF table rescan turned out empty eligible FCF, and the successful flogi
into an FCF shall clear the HBA_DEVLOSS_TMO flag, indicating the successful
recovery from devloss timeout.

ACPI table sysfs I/F is broken by commit
78f1699659963fff97975df44db6d5dbe7218e55
Author: Alex Chiang <achiang@hp.com>
Date: Sun Dec 20 12:19:09 2009 -0700
ACPI: processor: call _PDC early
because dynamic SSDT tables may be loaded in _PDC,
before installing the ACPI table handler.
As a result, the sysfs I/F of these dynamic tables are
located at /sys/firmware/acpi/tables instead of
/sys/firmware/acpi/tables/dynamic, which is not true.
Invoke acpi_sysfs_init() before acpi_early_processor_set_pdc(),
so that the table handler is installed before any dynamic tables loaded.
