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.

megaraid's MMIO RD*/WR* macros directly call readl() and writel() with

because the 'unsigned long' is really the result of ioremap(). This
setup is also OK because the variable can hold an ioremap cookie /or/ a
PCI I/O port (PIO).
However, to fix the warning thrown when readl() and writel() are passed
an unsigned long cookie, I introduce 'void __iomem *mmio_base', holding
the same value as 'base'. This will silence the warnings, and also
cause an oops whenever these MMIO-only functions are ever accidentally

[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).

[S390] cio: Make ccw_dev_id_is_equal() more robust.
Using memcmp to compare ccw_dev_id implies that the whole structure (incl.
padding) has always been completely initialized to sane values. Comparing
the structures field by field doesn't make such assumptions.

[S390] Convert extmem spin_lock into a mutex.
There's no need to have a spin_lock here, but need sleepable context
for vmem_map. Therefore convert the spin_lock into a mutex.

[S390] lockdep: show held locks when showing a stackdump
Follow i386/x86_64:
lockdep can be used to print held locks when printing a
backtrace. This can be useful when debugging things like
'scheduling while atomic' asserts.

[S390] Add dynamic size check for usercopy functions.
Use a wrapper for copy_to/from_user to chose the best usercopy method.
The mvcos instruction is better for sizes greater than 256 bytes, if
mvcos is not available a page table walk is better for sizes greater
than 1024 bytes. Also removed the redundant copy_to/from_user_std_small
functions.
