This reverts commit fd6e732186ab522c812ab19c2c5e5befb8ec8115, which
helped up things on MIPS, but was wrong for everything else. As Ralf
Baechle puts it:
"It seems the whole MIPS resource managment is complicated enough (out
of necessity) that only a few people actually grok it. Ioports being
actually memory mapped on MIPS only makes the confusion worse, sigh."

PowerMac and CHRP/BriQ platforms have quirks to switch some IDE
controllers from legacy mode to fully native mode. Those quirks
however will not work properly anymore due to a change to the
generic code to better handle legacy IDE resources.
This fixes it by moving those quirk to "early" quirks (so they
run before resources are probed for the devices) and clearing
all BARs after the conversion to force a reallocation of sane
values.

The recent I_LOCK->I_SYNC changes mistakenly changed xfs_ichgtime to look
at I_SYNC instead of I_LOCK. This was incorrect and prevents newly created
inodes from moving to the dirty list. Change this to the correct check
which is for I_NEW, not I_LOCK or I_SYNC so that behaviour is correct.

The current readdir implementation deadlocks on a btree buffers locks
because nfsd calls back into ->lookup from the filldir callback. The only

The radix tree based inode caches did away with the inode cluster hashes,
replacing them with a bunch of masking and gang lookups on the radix tree.
This masking got broken when moving the code to per-ag radix trees and
indexing by agino # rather than straight inode number. The result is
clustered inode writeback does not cluster and things can go extremely
slowly when there are lots of inodes to write.
Fix it up by comparing the agino # of the inode we just looked up to the
index of the cluster we are looking for.

- calculation of 'page_count' was incorrect as it did not
consider the offset of 'mem' into the first page. The
logic to bump 'page_count' didn't work if 'len' was <=
PAGE_CACHE_SIZE (ie offset = 3k, len = 2k).
- setting b_buffer_length to 'len' is incorrect if 'offset'
is > 0. Set it to the total length of the buffer.
- I suspect that passing a non-aligned address into
mem_to_page() for the first page may have been causing
issues - don't know but just tidy up that code anyway.

- sanity check for NULL user buffer in xfs_ioc_bulkstat[_compat]()
- remove the special case for XFS_IOC_FSBULKSTAT with count == 1. This
special case causes bulkstat to fail because the special case uses
xfs_bulkstat_single() instead of xfs_bulkstat() and the two functions
have different semantics. xfs_bulkstat() will return the next inode
after the one supplied while skipping internal inodes (ie quota inodes).
xfs_bulkstate_single() will only lookup the inode supplied and return
an error if it is an internal inode.
- in xfs_bulkstat(), need to initialise 'lastino' to the inode supplied
so in cases were we return without examining any inodes the scan wont
restart back at zero.
- sanity check for valid *ubcountp values. Cannot sanity check for valid
ubuffer here because some users of xfs_bulkstat() don't supply a buffer.
- checks against 'ubleft' (the space left in the user's buffer) should be
against 'statstruct_size' which is the supplied minimum object size.
The mixture of checks against statstruct_size and 0 was one of the
reasons we were skipping inodes.
- if the formatter function returns BULKSTAT_RV_NOTHING and an error and
the error is not ENOENT or EINVAL then we need to abort the scan. ENOENT
is for inodes that are no longer valid and we just skip them. EINVAL is
returned if we try to lookup an internal inode so we skip them too. For
a DMF scan if the inode and DMF attribute cannot fit into the space left
in the user's buffer it would return ERANGE. We didn't handle this error
and skipped the inode. We would continue to skip inodes until one fitted
into the user's buffer or we completed the scan.
- put back the recalculation of agino (that got removed with the last fix)
at the end of the while loop. This is because the code at the start of
the loop expects agino to be the last inode examined if it is non-zero.
- if we found some inodes but then encountered an error, return success
this time and the error next time. If the formatter aborted with ENOMEM
we will now return this error but only if we couldn't read any inodes.
Previously if we encountered ENOMEM without reading any inodes we
returned a zero count and no error which falsely indicated the scan was
complete.

The recent behaviour layer removal dropped the check for quotas that have
been requested at mount time but have subsequently been turned off. This
results in a panic when accessing m_quotainfo which has been freed.

Jan Altenberg <jan.altenberg@linutronix.de> reported that
building with redirected input like this failed:
make O=dir oldconfig bzImage < /dev/null
The problem were caused by a make silentoldconfig being
run before oldconfig and with a non-recent .config the build
failed because silentoldconfig requires non-redirected stdin.
Silentoldconfig was run as a side-effect of having the
top-level Makefile re-made by make.
Introducing an empty rule for the top-level Makefile
(and Kbuild.include) fixed the issue.

With the unionfs patch applied I get

the other architectures (some, at least) export copy_page() so I guess ia64
should also do so.
To do this we need to move the copy_page() functions out of lib.a and into

libata: kill spurious NCQ completion detection
ahci: don't attach if ICH6 is in combined mode
ata_piix: add Toshiba Tecra M4 to broken suspend list
ahci: fix engine reset failed message
|

Spurious NCQ completion detection implemented in ahci was incorrect.
On AHCI receving and processing FISes and raising interrupts are not
interlocked and spurious interrupts are expected.
For example, if an interrupt occurs while interrupt handler is running
and the running interrupt handler handles the event the new IRQ
indicated, after IRQ handler finishes, it will be executed again
because IRQ pending bit is set by the new interrupt but there won't be
anything to process.
Please read the following message for more information.
http://article.gmane.org/gmane.linux.ide/26012
This patch...
* Removes all spurious IRQ whining from ahci. Spurious NCQ completion
detection was completely wrong. Spurious D2H Register FIS taught us
that some early drives send spurious D2H Register FIS with I bit set
while NCQ commands are in progress but none of recent drives does
that and even the ones which show such behavior can do NCQ fine.
* Kills all NCQ blacklist entries which were added because of spurious
NCQ completions. I tracked down each commit and verified all
removed ones are actually added because of spurious completions.
WD740ADFD-00NLR1 wasn't deleted but moved upward because the drive
not only had spurious NCQ completions but also is slow on sequential
data transfers if NCQ is enabled.
Maxtor 7V300F0 was added by 0e3dbc01d53940fe10e5a5cfec15ede3e929c918
from Alan Cox. I can only find evidences that the drive only had
troubles with spuruious completions by searching the mailing list.
This entry needs to be verified and removed if it doesn't have other
NCQ related problems.

ICH6 R/Ms share PCI ID between piix and ahci modes and we've been
allowing ahci to attach regardless of how BIOS configured it.
However, enabling AHCI mode when the controller is in combined mode
can result in unexpected behavior. Don't attach if the controller is
in combined mode.
