[POWERPC] Early debug forces console log level to max
This makes the early debug option force the console loglevel
to the max. The early debug option is meant to catch messages very
early in the kernel boot process, in many cases, before the kernel
has a chance to parse the "debug" command line argument. Thus it
makes sense when CONFIG_PPC_EARLY_DEBUG is set, to force the console
log level to the max at boot time.

[POWERPC] Fix powerpc 32-bit resource fixup for 64-bit resources
The 32-bit powerpc resource fixup code uses unsigned longs to do the
offsetting of resources which overflows on platforms such as 4xx where
resources can be 64 bits.
This fixes it by using resource_size_t instead.
However, the IO stuff does rely on some 32 bits arithmetic, so we hack
by cropping the result of the fixups for IO resources with a 32 bits
mask.
This isn't the prettiest but should work for now until we change the
32 bits PCI code to do IO mappings like 64 bits does, within a reserved

Revert "PCI: fix IDE legacy mode resources"
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."

powerpc: Fix IDE legacy vs. native fixups
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.

[XFS] Fix broken inode cluster setup.
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.

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'

[XFS] 971064 Various fixups for xfs_bulkstat().
- 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.

libata: kill spurious NCQ completion detection
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

ibm_newemac: Cleanup/Fix RGMII MDIO support detection
More than just "AXON" version of EMAC RGMII supports MDIO, so replace
the current test with a generic property in the device-tree that
indicates such support.

ibm_newemac: Workaround reset timeout when no link
With some PHYs, when the link goes away, the EMAC reset fails due
to the loss of the RX clock I believe.
The old EMAC driver worked around that using some internal chip-specific
clock force bits that are different on various 44x implementations.
This is an attempt at doing it differently, by avoiding the reset when
there is no link, but forcing loopback mode instead. It seems to work
on my Taishan 440GX based board so far.

ibm_newemac: Fix ZMII refcounting bug
When using ZMII for MDIO only (such as 440GX with RGMII for data and ZMII for
MDIO), the ZMII code would fail to properly refcount, thus triggering a
BUG_ON().

make bnx2x select ZLIB_INFLATE
The bnx2x module depends on the zlib_inflate functions. The
build will fail if ZLIB_INFLATE has not been selected manually
or by building another module that automatically selects it.
Modify BNX2X config option to 'select ZLIB_INFLATE' like BNX2
and others. This seems to fix it.
