In order to speed up NFS reads, we attempt to copy directly from
skbuffs into the pagecache pages. As we cannot do XDR decoding in the
soft interrupts, we attempt to estimate the size of the RPC header (+
attributes,...) that will precede the actual data that goes in the
pagecache. If we get the estimate wrong, the XDR decode routines
perform a realignment of the data into the pagecache.

In the existing code, we do a multi-page kmap() from the xdr_buf into
an iovec array, in order to do the shift.

The following patch adds tools for doing the realigment without going
through the iovec array (and without having to do the deadlock-prone
multi-page kmap()).

It also adds the 2 helper routines xdr_read_pages()/xdr_write_pages()
which will be needed for NFSv4 reads/writes in order to add pre/post
operation GETATTR calls.

 - Move the encoding/decoding of the actual COMPOUND XDR header out of
   encode_compound()/decode_compound().

 - Make each NFSv4 operation 'decode_' routine also take care of
   decoding its own header, and checking it for correctness.
   Also allows us to get rid of the 'nfserr' parameter...

This fixes a couple of incorrect XDR buffer reservations.  The values
passed to RESERVE_SPACE() must reflect precisely the number of bytes
that we wish to send down the wire.

T_STRING token was used twice, so quoted strings use now T_WORD_QUOTE.

- allow double click to start edit of string symbols
- help text by Rod.VanMeter@nokia.com
- small reorganiztion to prepare for new features

Set geometry defaults, if TIOCGWINSZ fails.

Add a changed flag to properties, which can be used by front ends to check
for changed symbols/properties.

Enable dependencies for choice defaults.

- search for config files under $srctree (by Sam Ravnborg & me)
- allow to break long lines with \

Use all of choice input and don't ignore last character.

This fixes a threading/ptrace bug noticed by the gdb people: when a
thread is ptraced but other threads in the thread group are not then a
SIGTRAP (via int3 or any of the other debug traps) causes the child
thread(s) to die unexpectedly.  This is because the default behavior for
a no-handler SIGTRAP is to broadcast it.

The solution is to make all such signals specific, then the ptracer (gdb)
can filter the signal and upon continuation it's being handled properly
(or put on the shared signal queue). SIGKILL and SIGSTOP are an exception.
The patch only affects threaded and ptrace-d processes.

Robert made me notice that I forgot an explicit debugging printk()
inside the epoll module.

o Make the printk() to be debugging

This (from wli & myself) was overlooked for 2.5.51.  Without this fix,
sysfs panics when registering topology for NUMA boxen.

This renames more types and moves them into asm/compat.h and also
consolidates sys32_new{stat,fstat,lstat}.

Given Ralf's blessing, here is the mips64 part of the initial compatibility
syscall layer.

This patch creates compat_sys_times and a few more compability types.

This is the backwards compatibility code for MODULE_PARM, and moves
__MODULE_STRING() down to the graveyard at the bottom of module.h.

It's complicated by the fact that many modules place MODULE_PARM()
before the declaration (some do MODULE_PARM() for non-existant
variables, too).  To avoid breaking them, we have to do the name
lookups at load time, rather than just storing a pointer 8(

CONFIG_OBSOLETE_MODPARM is set to y without prompting: it's a useful
marker for deprecating in 2.7.

This activates parameter parsing for module_param() declarations in modules.

This patch is a rewrite of the insmod and boot parameter handling,
to unify them.

The new format is fairly simple: built on top of __module_param_call there
are several helpers, eg "module_param(foo, int, 000)".  The final argument
is the permissions bits, for exposing parameters in sysfs (if
non-zero) at a later stage.

I need to initialise the ad1848 driver before attempting attach/probe
from dependent drivers (e.g.  opl3sa2)

Fix for the compatibility layer for NULL 'remaining time' pointer.

Add sys_wait4 to the list of exported functions.

Warning fixes: remove an unused variable and make bitops complain if the
pointer isn't of type long. Make 31 bit BUG() emit 4 0-bytes instead of 2.
This improves the readability of the listing.

Make some functions and variables static.

Remove last remaining file of the old tape driver.
