[PATCH] knfsd: make nfsd readahead params cache SMP-friendly

Make the nfsd read-ahead params cache more SMP-friendly by changing the single
global list and lock into a fixed 16-bucket hashtable with per-bucket locks.
This reduces spinlock contention in nfsd_read() on read-heavy workloads on
multiprocessor servers.

Testing was on a 4 CPU 4 NIC Altix using 4 IRIX clients each doing 1K
streaming reads at full line rate.  The server had 128 nfsd threads, which
sizes the RA cache at 256 entries, of which only a handful were used.  Flat
profiling shows nfsd_read(), including the inlined nfsd_get_raparms(), taking
10.4% of each CPU.  This patch drops the contribution from nfsd() to 1.71% for
each CPU.

[PATCH] knfsd: Allow max size of NFSd payload to be configured

The max possible is the maximum RPC payload.  The default depends on amount of
total memory.

The value can be set within reason as long as no nfsd threads are currently
running.  The value can also be ready, allowing the default to be determined
after nfsd has started.

[PATCH] knfsd: Prepare knfsd for support of rsize/wsize of up to 1MB, over TCP

The limit over UDP remains at 32K.  Also, make some of the apparently
arbitrary sizing constants clearer.

The biggest change here involves replacing NFSSVC_MAXBLKSIZE by a function of
the rqstp.  This allows it to be different for different protocols (udp/tcp)
and also allows it to depend on the servers declared sv_bufsiz.

Note that we don't actually increase sv_bufsz for nfs yet.  That comes next.

[PATCH] knfsd: Avoid excess stack usage in svc_tcp_recvfrom

..  by allocating the array of 'kvec' in 'struct svc_rqst'.

As we plan to increase RPCSVC_MAXPAGES from 8 upto 256, we can no longer
allocate an array of this size on the stack.  So we allocate it in 'struct
svc_rqst'.

However svc_rqst contains (indirectly) an array of the same type and size
(actually several, but they are in a union).  So rather than waste space, we
move those arrays out of the separately allocated union and into svc_rqst to
share with the kvec moved out of svc_tcp_recvfrom (various arrays are used at
different times, so there is no conflict).

[PATCH] knfsd: Replace two page lists in struct svc_rqst with one

We are planning to increase RPCSVC_MAXPAGES from about 8 to about 256.  This
means we need to be a bit careful about arrays of size RPCSVC_MAXPAGES.

struct svc_rqst contains two such arrays.  However the there are never more
that RPCSVC_MAXPAGES pages in the two arrays together, so only one array is
needed.

The two arrays are for the pages holding the request, and the pages holding
the reply.  Instead of two arrays, we can simply keep an index into where the
first reply page is.

This patch also removes a number of small inline functions that probably
server to obscure what is going on rather than clarify it, and opencode the
needed functionality.

Also remove the 'rq_restailpage' variable as it is *always* 0.  i.e.  if the
response 'xdr' structure has a non-empty tail it is always in the same pages
as the head.

[PATCH] knfsd: call lockd_down when closing a socket via a write to nfsd/portlist

The refcount that nfsd holds on lockd is based on the number of open sockets.
So when we close a socket, we should decrement the ref (with lockd_down).

Currently when a socket is closed via writing to the portlist file, that
doesn't happen.

So: make sure we get an error return if the socket that was requested does is
not found, and call lockd_down if it was.

[PATCH] mmc: use own work queue

The MMC layer uses the standard work queue for doing card detection.  As this
queue is shared with other crucial subsystems, the effects of a long (and
perhaps buggy) detection can cause the system to be unusable.  E.g.  the
keyboard stops working while the detection routine is running.

The solution is to add a specific mmc work queue to run the detection code in.
This is similar to how other subsystems handle detection (a full kernel
thread is the most common theme).

The cause of this problem might be an wrong assumption that the 'start'
member of resource structure for ioapic device has non-zero value if the
resources are assigned by firmware.  The 'start' member of ioapic device
seems not to be set even though the resources were actually assigned to
ioapic devices by firmware.

V4L/DVB (4681): Cx88: fix analog capture notch filter

This patch changes the setting of the cx2388x notch filter to match that of
the video capture sample frequency, removing some annoying interference
lines THAT would appear when capturing composite video. This has been tested
in PAL and NTSC TV norms.
It sets the Y/C separation luma notch filter, which removes the chroma signal
from the luma signal when using a composite input.
The luma notch filter operates at the video decoder's frequency, not the ADC's
frequency or at the frequency of the scaled video. Y/C separation happens after
the sample rate converter, before video scaling.
The datasheet provides plots of the filter response for three _video decoder_
frequencies, 4x Fsc, square pixel, and ccir601.  These are the same three
frequencies for the notch filter control.  It seems pretty clear that this
filter should be set based on the video decoder frequency. The cx88 driver
always uses a video decoder frequency of 4xFsc.
