Previously, fatfs was using NLS_DEFAULT if users didn't specify the
codepage or iocharset option.  This became cause of trouble (filename
access).

This patch removes the complicated default config in kernel.

Instead of it, by default, fatfs uses builtin nls ("default"), also reports
it and mounts as read-only.  This default will limit the access more or
less.  Note: If peoples want to write on this default, it still can switch
by remount.

Therefore, basically users will need to specify mount options always.
("codepage" for msdos, and "codepage" and "iocharset" for vfat) However, it
can be done simply by script or shell alias or something else in userland.

Thanks to Andries Brouwer for your many advice.

There is a lonstanding off-by-one error that results from an incorrect
comparison when checking whether a process has consumed CPU time in
excess of its RLIMIT_CPU limits. 

This means, for example, that if we use setrlimit() to set the soft CPU 
limit (rlim_cur) to 5 seconds and the hard limit (rlim_max) to 10 seconds, 
then the process only receives a SIGXCPU signal after consuming 6 seconds
of CPU time, and, if it continues consuming CPU after handling that
signal, only receives SIGKILL after consuming 11 seconds of CPU time.

The fix is trivial.

The nfs_fill_super() fix is obvious and in nfs4_fill_super(), the
server->client ptr needs to be set before the cl_idmap check, since
rpc_shutdown_client() needs it when the check fails.

Actually, the problem has its origin in my removal of all in-kernel
syscalls (except execve, which is non-trivial) earlier this year.  This
change was blindly reverted by the maintainer, while at the same time the
local errno variable was removed.  See also
http://linux.bkbits.net:8080/linux-2.5/hist/drivers/media/dvb/frontends/tda=
1004x.c

This patch is the one that was already merged earlier.  I'm now also
removing the definitions for the kernel syscalls on i386 to make it harder
to reintroduce them again.  This was already done for ppc64, the others
should probably follow.

The "vector" terminology is architecture-dependent.  The PCI MSI interface

Rewrite/cleanup of the SLB management code.  This removes nearly all the
SLB related code from arch/ppc64/kernel/stab.c and puts a rewritten version
in arch/ppc64/mm, where it better belongs.  The main SLB miss path is in
assembler and the other routines have been cleaned up and streamlined.

Notable changes:

- Ugly bitfields no longer used for generating SLB entries.

- slb_allocate() (the main SLB miss routine) is now in assembler, and all
  the data it uses is stored in the PACA.

- The mm context is now copied into the PACA at context switch time, to
  avoid looking up the thread struct on SLB miss.

- An SLB miss will now never (directly) result in a call to
  do_page_fault.  If we get a miss on a totally bogus address the handler
  will now put in an SLB referencing VSID 0.  This will never have any
  pages, so we'll get the (fatal) page fault shortly afterwards.  This
  simplifies the SLB entry and exit paths.

- The round-robin pointer in the PACA now references the last-used
  instead of next-to-use SLB slot, which simplifies the asm for updating it
  slightly.

- Unify do_slb_bolted with the general SLB miss path.  There is now one
  SLB miss handler, in assembler, and called with only the low-level
  exception prolog (EXCEPTION_PROLOG_[PI]SERIES rather than
  EXCEPTION_PROLOG_COMMON) and minimal extra save/restore logic.

- Streamlines the exception entry/exit path of the SLB miss handler to
  shave a few cycles off.  The most significant change is that the RI bit
  is left off throughout the whole handler, which avoids an extra mtmsrd to
  turn it back off on the exit path.
