warning: implicit declaration of function `smp_local_timer_interrupt'

 When I was searching for prototype for set_bit() I found IMHO wrong doc
entries in include/asm-i386/bitops.h.

This is the 2nd version Torben did, basically the same as the one from
yesterday but with symbolic tune defines instead of more magic numbers.
I think the feature is good to have, and it would even allow good ide
performance even for an unsupported chipset as long as the bios sets the
timings right.

From Torben Mathiasen.

Lets just make the default fifo_batch count 16. I see a slight slope in
throughput, but the various interactiveness improvements are worth it,
imho. Plus this gets Andrew of my back, he's been lobbying for this for
a while.

Right now we have one type of barrier in the block layer, and that is
used mainly for making sure that the io scheduler doesn't reorder
requests when we don't want it to.  We also need a flag to tell the io
scheduler and low level queue that this is a barrier.  So basically two
needs:

o software barrier, prevents the io scheduler from reordering
o hardware barrier, driver must prevent drive from reordering

So this patch gets rid of REQ_BARRIER and instead adds REQ_SOFTBARRIER
and REQ_HARDBARRIER.

o Correct printk() format, from Marcelo Roberto Jimenez
o Check for NULL address in cdrom_newpc_intr() and bail

Label in wrong place.

Ensure that we can still flush out a minimum number of read, write,
and commit requests if memory gets low.

nfs_find_request() needs to be called every time we schedule a write
on the page cache. Currently it is implemented as a linked list which
needs to be traversed completely in the case where we don't already
have a pending write request on the page in question.

The following patch adopts the new radix tree, as is already used in
the page cache. Performance change is more or less negligeable with
the current hard limit of 256 outstanding write requests per mount.

However when I remove this limit then the old nfs_find_request()
actually results in a 50% reduction in speed on my benchmark test
(iozone with 4 threads each writing a 512Mb file on a 512Mb Linux
client against a Solaris server on 100Mbit switched net). With this
patch, the result for the same benchmark is a 50% increase in speed.

The following patch adds a simple ->writepages method that interprets
the extra information passed down in Andrew's writeback_control
structure, and translates it into nfs-speak.

It also adds a backing_dev_info structure that scales the readahead in
terms of the rsize. Maximum readahead is still 128k if you use 32k
rsize, but it is scaled down to 4k if you use 1k rsize.

Stub out put_dirty_page and setup_arg_pages for !CONFIG_MMU and add
free_arg_pages that frees all arg pages (noop for CONFIG_MMU)

find out the effective size of a kmalloc()ed object, needed by uClinux
but also usefull for the "normal" ports, thus not ifdef'ed.

Proper wakeup code in ep_insert and ep_modify

This trivial patch fixes a mixer problem with the emu10k1 driver in
ALSA.  In sound/pci/emu10k1/emufx.c, the line

static const u32 bass_table[41][5] = {

only has 40 lines defined, instead of 41.  This results in no sound
output when the bass control is set at 100% (but works fine at 98%) I
added the missing line, which is present in the OSS emu10k1 driver.

This makes it possible for binfmt_misc to optionally preserve the
contents of argv[1].  This is needed for building accurate simulators
which are invoked via binfmt_misc.  I had brought up this patch a while
ago (see URL below) and there was no negative feedback (OK, there was no
feedback at all...  ;-).

The patch is trivial and the new behavior is triggered only if the
letter "P" (for "preserve") is appended to the binfmt_misc registration
string, so it shold be completely safe.

1. Expiration of SAs. Some missing updates of counters.
   Question: very strange, rfc defines use_time as time of the first use
   of SA. But kame setkey refers to this as lastuse.
2. Bug fixes for tunnel mode and forwarding.
3. Fix bugs in per-socket policy: policy entries do not leak but are destroyed,
   when socket is closed, and are cloned on children of listening sockets.
4. Implemented use policy: i.e. use ipsec if a SA is available,
   ignore if it is not.
5. Added sysctl to disable in/out policy on some devices.
   It is set on loopback by default.
6. Remove resolved reference from template. It is not used,
   but pollutes code.
7. Added all the SASTATEs, now they make sense.

Clean up vfs_readv/writev() interface and avoid code duplication.

Make kNFSd use the cleaned-up interfaces, and disable the code that
accesses the low-level readpage() function of the exported filesystem
(not allowed - many filesystems need extra setup, which is why we have
a separate ->sendpage() routine for that).

Change ARCH_STACK_GROWSUP to CONFIG_STACK_GROWSUP as requested.

The hugetlb page support in 2.5.46 is broken (Don't know if this is the
first version of kernel or any prior revs also have that).  Basically the
free side of hugepages was really not freeing the physical resources (for
the cases when the pages allocated using system call interface).  Attached
is the patch that should resolve it. (doesn't break the hugetlbfs support
either).

NFSv2 doesn't pass connectathon 2002, at least on some Linux kernels.
Trond deemed the following modification necessary in all kernels to
address the problem.
