UHCI: no dummy TDs for Iso QHs
Isochronous queues don't need a dummy TD because the Queue Header

The patch also fixes a long-standing typo in a comment (a "don't" was

USB: add binary API to usbmon
This patch adds a new, "binary" API in addition to the old, text API usbmon
had before. The new API allows for less CPU use, and it allows to capture
all data from a packet where old API only captured 32 bytes at most. There
are some limitations and conditions to this, e.g. in case someone constructs
a URB with 1GB of data, it's not likely to be captured, because even the
huge buffers of the new reader are finite. Nonetheless, I expect this new
capability to capture all data for all real life scenarios.
The downside is, a special user mode application is required where cat(1)
worked before. I have sample code at http://people.redhat.com/zaitcev/linux/

This patch was initially written by Paolo and later I tweaked it, and

rndis_host learns ActiveSync basics
Windows Mobile 5 based devices described as supporting "ActiveSync":
- Speak RNDIS but lack the CDC and union descriptors. This patch
updates the cdc ethernet code to fake ACM descriptors we need.
- Require RNDIS_MSG_QUERY messages to include a buffer of the size the
response should generate. This patch updates the rndis host code to
pass this will-be-ignored data.
The resulting RNDIS host code has been reported to work with several
WM5 based devices.
(Note that a fancier patch is available at synce.sf.net.)
Some bugfixes, affecting not just ActiveSync:
(a) when cleaning up after RNDS init fails, scrub the second interface
just like cdc_ether does, so disconnect won't oops.
(b) handle peripherals that use the pad-to-end-of-packet option; some
devices can't talk to us if that option doesn't work.
(c) when choosing configurations, don't forget about an RNDIS config
just because the RNDIS driver is dynamically linked.
Cleanup, streamlining, bugfixes, Kconfig, and matching hub driver update.
Also for paranoia's sake, refuse to talk to something that looks like a

This patch adds those descriptors, so systems using PXA 255 processors

This is a Good Thing since Microsoft's RNDIS code has bugginess issues,

[PATCH] Keys: Fix key serial number collision handling
Fix the key serial number collision avoidance code in key_alloc_serial().
This didn't use to be so much of a problem as the key serial numbers were
allocated from a simple incremental counter, and it would have to go through
two billion keys before it could possibly encounter a collision. However, now
that random numbers are used instead, collisions are much more likely.
This is fixed by finding a hole in the rbtree where the next unused serial
number ought to be and using that by going almost back to the top of the
insertion routine and redoing the insertion with the new serial number rather
than trying to be clever and attempting to work out the insertion point
pointer directly.
This fixes kernel BZ #7727.

[MIPS] Alchemy: Fix PCI-memory access
The problem was introduced in 2.6.18.3 with the casting of some
36bit-defines (PCI memory) in au1000.h to resource_size_t which may be
u32 or u64 depending on the experimental CONFIG_RESOURCES_64BIT.
With unset CONFIG_RESOURCES_64BIT, the pci-memory cannot be accessed
because the ioremap in arch/mips/au1000/common/pci.c already used the
truncated addresses.
With set CONFIG_RESOURCES_64BIT, things get even worse, because PCI-scan
aborts, due to resource conflict: request_resource() in arch/mips/pci/pci.c
fails because the maximum iomem-address is 0xffffffff (32bit) but the
pci-memory-start-address is 0x440000000 (36bit).
To get pci working again, I propose the following patch:
1. remove the resource_size_t-casting from au1000.h again
2. make the casting in arch/mips/au1000/common/pci.c (it's allowed and
necessary here. The 36bit-handling will be done in __fixup_bigphys_addr).
With this patch pci works again like in 2.6.18.2, the gcc-compile warnings
in pci.c are gone and it doesn't depend on CONFIG_EXPERIMENTAL.

The irq_base for {mips,rm7k,rm9k}_cpu_irq_init() are constant on all
platforms and are same value on most platforms (0 or 16, depends on
CONFIG_I8259). Define them in asm-mips/mach-generic/irq.h and make
them customizable. This will save a few cycle on each CPU interrupt.
A good side effect is removing some dependencies to MALTA in generic
SMTC code.
Although MIPS_CPU_IRQ_BASE is customizable, this patch changes irq
mappings on
DDB5477, EMMA2RH and MIPS_SIM, since really customizing
them might cause some header dependency problem and there seems no
good reason to customize it. So currently only VR41XX is using custom
MIPS_CPU_IRQ_BASE value, which is 0 regardless of CONFIG_I8259.

[GFS2] nfsd readdirplus assertion failure
Glock assertion failure found in '07 NFS connectathon. One of the NFSDs
is doing a "readdirplus" procedure call. It passes the logic into
gfs2_readdir() where it obtains its directory inode glock. This is then
followed by filehandle construction that invokes lookup code. It hits
the assertion failure while trying to obtain the inode glock again
inside gfs2_drevalidate().
This patch bypasses the recursive glock call if caller already holds the
lock.

[IA64] register memory ranges in a consistent manner
While pursuing and unrelated issue with 64Mb granules I noticed a problem
related to inconsistent use of add_active_range. There doesn't appear any
reason to me why FLATMEM versus DISCONTIG_MEM should register memory to
add_active_range with different code. So I've changed the code into a
common implementation.
The other subtle issue fixed by this patch was calling add_active_range in
count_node_pages before granule aligning is performed. We were lucky with
16MB granules but not so with 64MB granules. count_node_pages has reserved
regions filtered out and as a consequence linked kernel text and data
aren't covered by calls to count_node_pages. So linked kernel regions
wasn't reported to add_active_regions. This resulted in free_initmem
causing numerous bad_page reports. This won't occur with this patch
because now all known memory regions are reported by
register_active_ranges.
