Provide a module param "pool_mode" for sunrpc.ko which allows a sysadmin to
choose the mode for mapping NFS thread service pools to CPUs. Values are:
auto choose a mapping mode heuristically
global (default, same as the pre-2.6.19 code) a single global pool
percpu one pool per CPU
pernode one pool per NUMA node
Note that since 2.6.19 the hardcoded behaviour has been "auto", this patch
makes the default "global".
The pool mode can be changed after boot/modprobe using /sys, if the NFS and
lockd services have been shut down. A useful side effect of this change is to
fix a small memory leak when unloading the module.

The driver didn't allow to disable the integrated FM port (if available),
and this annoyed people who don't want FM port. Now fm_port=0 disables
the FM port unconditionally. fm_port=1 is used for enabling the integrated

Also fixed the documentation about this option.

Since wext is being replaced as fast as we can (it'll probably stick around
for legacy drivers though) and the wext/netlink stuff was never really
used, this schedules it for removal.
The removal schedule is tight but there are no users of the code, the main
user of the wext user interface are the wireless-tools, they only have an
alpha version using the netlink interface and even that is incomplete.

Legacy IDE VLB host drivers didn't check for "probe" options when compiled

The SUN_AURORA driver:
- has been marked as BROKEN for more than two years and
- is still marked as BROKEN.
Drivers that had been marked as BROKEN for such a long time seem to be
unlikely to be revived in the forseeable future.
But if anyone wants to ever revive this driver, the code is still
present in the older kernel releases.

This patch (as859) makes the default USB autosuspend delay a module
parameter of usbcore. By setting the delay value at boot time, users
will be able to prevent the system from autosuspending devices which
for some reason can't handle it.
The patch also stores the autosuspend delay as a per-device value. A
later patch will allow the user to change the value, tailoring the
delay for each individual device. A delay value of 0 will prevent
autosuspend.

simple_prepare_write leaks uninitialised kernel data. This happens because
the it leaves an uninitialised "hole" over the part of the page that the
write is expected to go to. This is fine, but it then marks the page
uptodate, which means a concurrent read can come in and copy the
uninitialised memory into userspace before it written to.
Fix it by simply marking it uptodate in simple_commit_write instead, after
the hole has been filled in. This could theoretically break an fs that
uses simple_prepare_write and not simple_commit_write, and that relies on
the incorrect simple_prepare_write behaviour. Luckily, none of those
exists in the tree.

While cacheing is generally frowned upon in the 9p world, it has its
place -- particularly in situations where the remote file system is
exclusive and/or read-only. The vacfs views of venti content addressable
store are a real-world instance of such a situation. To facilitate higher
performance for these workloads (and eventually use the fscache patches),
we have enabled a "loose" cache mode which does not attempt to maintain
any form of consistency on the page-cache or dcache. This results in over
two orders of magnitude performance improvement for cacheable block reads
in the Bonnie benchmark. The more aggressive use of the dcache also seems
to improve metadata operational performance.
