Ultimately to implement /proc perfectly we need an implementation of
d_revalidate because files and directories can be removed behind the back
of the VFS, and d_revalidate is the only way we can let the VFS know that
this has happened.
Unfortunately the linux VFS can not cope with anything in the path to a
mount point going away. So a proper d_revalidate method that calls d_drop
also needs to call have_submounts which is moderately expensive, so you
really don't want a d_revalidate method that unconditionally calls it, but
instead only calls it when the backing object has really gone away.
proc generic entries only disappear on module_unload (when not counting the
fledgling network namespace) so it is quite rare that we actually encounter
that case and has not actually caused us real world trouble yet.
So until we get a proper test for keeping dentries in the dcache fix the
current d_revalidate method by completely removing it. This returns us to
the current status quo.
So with CONFIG_NETNS=n things should look as they have always looked.
For CONFIG_NETNS=y things work most of the time but there are a few rare
corner cases that don't behave properly. As the network namespace is
barely present in 2.6.24 this should not be a problem.

We have a wifi module connected to the spi bus and got sometimes FIFO
overrun errors on the spi bus.
After some investigation i found that the driver loads the TCR (transmit
count) register before the RCR (receive count). When the transfer list is
not empty the atmel_spi_next_message is called while tx and rx are enabled.
As soon as the TCR is loaded, hardware starts transfer and causes a rx
fifo overrun because the RCR is not loaded yet.
Load the RCR before the TCR. After this patch the fifo overrun disapears
at out setup.

The esp_reset_cleanup() function is called with the host lock held and
invokes starget_for_each_device() which wants to take it too. Here is a
fix along the lines of shost_for_each_device()/__shost_for_each_device()
adding a __starget_for_each_device() counterpart which assumes the lock
has already been taken.
Eventually, I think the driver should get modified so that more work is
done as a softirq rather than in the interrupt context, but for now it
fixes a bug that causes the spinlock debugger to fire.
While at it, it fixes a small number of cosmetic problems with
starget_for_each_device() too.

The follow_hugetlb_page() fix I posted (merged as git commit
5b23dbe8173c212d6a326e35347b038705603d39) missed one case. If the pte is
present, but not writable and write access is requested by the caller to
get_user_pages(), the code will do the wrong thing. Rather than calling
hugetlb_fault to make the pte writable, it notes the presence of the pte
and continues.
This simple one-liner makes sure we also fault on the pte for this case.
Please apply.

Third rendition of FireWire OHCI 1.0 Isochronous Receive support, using a
zer-copy method similar to OHCI 1.1 which puts the IR data payload directly
into the userspace buffer. The zero-copy implementation eliminates the
video artifacts, audio popping, and buffer underrun problems seen with
version 1 of this patch, as well as fixing a regression in OHCI 1.1 support
introduced by version 2 of this patch.
Successfully tested in OHCI 1.1 mode on the following chipsets:
- NEC uPD72847 (rev 01), OHCI 1.1 (PCI)
- Ti XIO2200(A) (rev 01), OHCI 1.1 (PCIe)
- Ti TSB41AB2 (rev 01), OHCI 1.1 (PCI on SB Audigy)
- Apple UniNorth 2 (rev 81), OHCI 1.1 (PowerBook G4 onboard)
Successfully tested in OHCI 1.0 mode on the following chipsets:
- Agere FW323 (rev 06), OHCI 1.0 (Mac Mini onboard)
- Agere FW323 (rev 06), OHCI 1.0 (PCI)
- Via VT6306 (rev 46), OHCI 1.0 (PCI)
- NEC OrangeLink (rev 01), OHCI 1.0 (PCI)
- NEC uPD72847 (rev 01), OHCI 1.1 (PCI)
- Ti XIO2200(A) (rev 01), OHCI 1.1 (PCIe)
The bulk of testing was done in an x86_64 system, but was also successfully
sanity-tested on other systems, including a PPC(32) PowerBook G4 and an i686
EPIA M10k. Crude benchmarking (watching top during capture) puts the cpu
utilization during capture on the EPIA's 1GHz Via C3 processor around 13%,
which is down from 30% with the v1 code.
Some implementation details:
To maintain the same userspace API as dual-buffer mode, we set up two
descriptors for every incoming packet. The first is an INPUT_MORE descriptor,
pointing to a buffer large enough to hold just the packet's iso headers,
immediately followed by an INPUT_LAST descriptor, pointing to a chunk of the
userspace buffer big enough for the packet's data payload. With this setup,
each incoming packet fills in these two descriptors in a manner that very
closely emulates dual-buffer receive, to the point where the bulk of the
handle_ir_* code is now identical between the two (and probably primed for
some restructuring to share code between them).
The only caveat I have at the moment is that neither of my OHCI 1.0 Via
VT6307-based FireWire controllers work particularly well with this code
for reasons I have yet to figure out.

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 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.

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.

'!' has a higher priority than '&', so as was
this won't test the first bit, but rather evaluates to false for any non-zero
lsapic->lapic_flags.

Rename _bss to __bss_start as on other architectures. That makes it
possible to use the <linux/sections.h> instead of own declarations. Also
add __bss_stop because that symbol exists on other architectures.

When initializing pci_controller->node to point to the closest node we need
to take into consideration that a PIC PCI Bridge ASIC can be connected to a
headless/memless node just like the TIOCP and TIOCE Bridge ASICs

With the unionfs patch applied I get
ERROR: "copy_page" [fs/unionfs/unionfs.ko] undefined!
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
built-in.o and add the EXPORT_SYMBOL().
