rpc: spkm3 update
This updates the spkm3 code to bring it up to date with our current
understanding of the spkm3 spec.
In doing so, we're changing the downcall format used by gssd in the spkm3 case,
which will cause an incompatilibity with old userland spkm3 support. Since the
old code a) didn't implement the protocol correctly, and b) was never
distributed except in the form of some experimental patches from the citi web
site, we're assuming this is OK.
We do detect the old downcall format and print warning (and fail). We also
include a version number in the new downcall format, to be used in the
future in case any further change is required.
In some more detail:
- fix integrity support
- removed dependency on NIDs. instead OIDs are used
- known OID values for algorithms added.
- fixed some context fields and types

NFS: Fix asynchronous read error handling
We must always call ->read_done() before we truncate the page data, or
decide to flag an error. The reasons are that
in NFSv2, ->read_done() is where the eof flag gets set.
in NFSv3/v4 ->read_done() handles EJUKEBOX-type errors, and
v4 state recovery.
However, we need to mark the pages as uptodate before we deal with short
read errors, since we may need to modify the nfs_read_data arguments.
We therefore split the current nfs_readpage_result() into two parts:
nfs_readpage_result(), which calls ->read_done() etc, and
nfs_readpage_retry(), which subsequently handles short reads.
Note: Removing the code that retries in case of a short read also fixes a
bug in nfs_direct_read_result(), which used to return a corrupted number of
bytes.

Subject: Re: [PATCH] Fix SUNRPC wakeup/execute race condition
The sunrpc scheduler contains a race condition that can let an RPC
task end up being neither running nor on any wait queue. The race takes
place between rpc_make_runnable (called from rpc_wake_up_task) and
__rpc_execute under the following condition:
First __rpc_execute calls tk_action which puts the task on some wait
queue. The task is dequeued by another process before __rpc_execute
continues its execution. While executing rpc_make_runnable exactly after
setting the task `running' bit and before clearing the `queued' bit
__rpc_execute picks up execution, clears `running' and subsequently
both functions fall through, both under the false assumption somebody
else took the job.
Swapping rpc_test_and_set_running with rpc_clear_queued in
rpc_make_runnable fixes that hole. This introduces another possible
race condition that can be handled by checking for `queued' after
setting the `running' bit.
Bug noticed on a 4-way x86_64 system under XEN with an NFSv4 server
on the same physical machine, apparently one of the few ways to hit
this race condition at all.

Centralising the definition in linux/types.h means that arch maintainers
don't need to bother adding it, as well as fixing the problem with
x86-64 users being asked to make a decision that has absolutely no
effect.
The H8/300 porters seem particularly confused since I'm not aware of any
microcontrollers that need to support 2TB filesystems.

[PATCH] remote memory corruptor in ibmtr.c
ip_summed changes last summer had missed that one. As the result,
we have ip_summed interpreted as CHECKSUM_PARTIAL now. IOW,
->csum is interpreted as offset of checksum in the packet. net/core/*
will both read and modify the value as that offset, with obvious
reasons. At the very least it's a remote memory corruptor.

[PATCH] pcmcia: multifunction card handling fixes
s->functions needs to be initialized earlier, for the "let's see
how high it increases" approach means that pcmcia_request_irq()
(which makes use of this value) is confused, and might request
an exclusive IRQ first even though it is not supposed to.
Also, a CIS override autoloaded using the firmware loader may
allow for the use of more or less functions in a multifunction
card. Therefore, we may need to schedule a call to add this
second function later on, or simply remove the other function
(it's always the first -valid- function which reaches this
codepath).
