  [GFS2] Fix Kconfig
  [DLM] fix compile warning

Problem:
  sched_fork() has always called scheduler_tick() in some (unlikely)
  circumstances in order to update the current task in light of those
  circumstances.  It has always been the case that the work done by
  scheduler_tick() was more than was required to handle the problem in
  hand but no harm was done except for the waste of a few CPU cycles.

  However, the splitting of scheduler_tick() into two procedures in
  2.6.20-rc1 enables the wasted cycles to be saved as the new procedure
  task_running_tick() does all the work that is required to rectify the
  problem being handled.

Solution:
  Replace the call to scheduler_tick() in sched_fork() with a call to
  task_running_tick().

if CONFIG_CALGARY_IOMMU is built into the kernel via
CONFIG_CALGARY_IOMMU_ENABLED_BY_DEFAULT, or is enabled via the
iommu=calgary boot option, then the detect_calgary() function runs to
detect the presence of a Calgary IOMMU.

detect_calgary() first searches the BIOS EBDA area for a "rio_table_hdr"
BIOS table. It has this parsing algorithm for the EBDA:

	while (offset) {
		...
		/* The next offset is stored in the 1st word. 0 means no more */
 		offset = *((unsigned short *)(ptr + offset));
	}

got that? Lets repeat it slowly: we've got a BIOS-supplied data
structure, plus Linux kernel code that will only break out of an
infinite parsing loop once the BIOS gives a zero offset. Ok?

Translation: what an excellent opportunity for BIOS writers to lock up
the Linux boot process in an utterly hard to debug place! Indeed the
BIOS jumped on that opportunity on my box, which has the following EBDA
chaining layout:

  384, 65282, 65535, 65535, 65535, 65535, 65535, 65535 ...

see the pattern? So my, definitely non-Calgary system happily locks up
in detect_calgary()!

the patch below fixes the boot hang by trusting the BIOS-supplied data
structure a bit less: the parser always has to make forward progress,
and if it doesnt, we break out of the loop and i get the expected kernel
message:

  Calgary: Unable to locate Rio Grande Table in EBDA - bailing!

one of my boxes didnt boot the 2.6.20-rc1-rt0 kernel rpm, it hung during
early bootup. After an hour or two of happy debugging i narrowed it down
to the CALGARY_IOMMU_ENABLED_BY_DEFAULT option, which was freshly added
to 2.6.20 via the x86_64 tree and /enabled by default/.

commit bff6547b claims:

    [PATCH] Calgary: allow compiling Calgary in but not using it by default

    This patch makes it possible to compile Calgary in but not use it by
    default. In this mode, use 'iommu=calgary' to activate it.

but the change does not actually practice it:

 config CALGARY_IOMMU_ENABLED_BY_DEFAULT
        bool "Should Calgary be enabled by default?"
        default y
        depends on CALGARY_IOMMU
        help
          Should Calgary be enabled by default? if you choose 'y', Calgary
          will be used (if it exists). If you choose 'n', Calgary will not be
          used even if it exists. If you choose 'n' and would like to use
          Calgary anyway, pass 'iommu=calgary' on the kernel command line.
          If unsure, say Y.

it's both 'default y', and says "If unsure, say Y". Clearly not a typo.

disabling this option makes my box boot again. The patch below fixes the
Kconfig entry. Grumble.

libata depended on SCSI command to have the correct length when
tranlating it into an ATA command.  This generally worked for commands
issued by SCSI HLD but user could issue arbitrary broken command using
sg interface.

Also, when building ATAPI command, full command size was always
copied.  Because some ATAPI devices needs bytes after CDB cleared, if
upper layer doesn't clear bytes after CDB, such devices will
malfunction.  This necessiated recent clear-garbage-after-CDB fix in
sg interfaces.  However, scsi_execute() isn't fixed yet and HL-DT-ST
DVD-RAM GSA-H30N malfunctions on initialization commands issued from
SCSI.

This patch makes xlat functions always consider SCSI cmd_len.  Each
translation function checks for proper cmd_len and ATAPI translaation
clears bytes after CDB.

Variable names in xlat functions are quite confusing now.  'scsicmd'

'cmd' is used for struct scsi_cmnd.

This patch cleans up variable names in xlat functions such that 'scmd'
is used for struct scsi_cmnd and 'cdb' for CDB.  Also, 'scmd' local
variable is added if qc->scsicmd is used multiple times.

Since commit 368c73d4 the kernel will try
to update the non-writeable BAR registers 0..3 of PIIX4 IDE adapters if
pci_assign_unassigned_resources() is used to do full resource assignment of
the bus.  This fails because in the PIIX4 these BAR registers have
implicitly assumed values and read back as zero; it used to work because
the kernel used to just write zero to that register the read back value did
match what was written.

The fix is a new resource flag IORESOURCE_PCI_FIXED used to mark a resource
as non-movable.  This will also be useful to keep other import system
resources from being moved around - for example system consoles on PCI
busses.

This patch is designed to fix:
- Disk eating corruptor on KT7 after resume from RAM
- VIA IRQ handling
- VIA fixups for bus lockups after resume from RAM

The core of this is to add a table of resume fixups run at resume time.
We need to do this for a variety of boards and features, but particularly
we need to do this to get various critical VIA fixups done on resume.

The second part of the problem is to handle VIA IRQ number rules which
are a bit odd and need special handling for PIC interrupts. Various
patches broke various boxes and while this one may not be perfect
(hopefully it is) it ensures the workaround is applied to the right
devices only.

From: Jean Delvare <khali@linux-fr.org>

Now that PCI quirks are replayed on software resume, we can safely
re-enable the Asus SMBus unhiding quirk even when software suspend support
is enabled.
