This adds detailed documentation concerning how we map the Linux
page table structure onto the hardware tables on ARM.  In addition,
it also adds documentation describing how we emulate the "dirty"
and "young" or "accessed" page table bits.

This should be of interest to Linux MM developers.

The just merged openpromfs remount patch contains a silly typo in the
field of the super_operations structure.

Fixed like this.

When the pcnet32 adapter is installed in a system with long PCI latency
and the read burst bit is not set, performance on transmission is very
low (under 20Mbit on a 100Mbit link).  This patch against 2.6.6-rc1 will
make sure that read and write bursts are enabled.  Tested on ppc64 and
ia32.

Noticed by Roger Luethi, via-rhine maintainer.

Many binutils versions over the last year appear to silently build
assembler files with undefined constants, and able to successfully
create executables from such files.  The assembler appears to add
undefined symbols to the symbol table without any corresponding
relocation information.  Obviously this is bad news since the
resulting executable may not be what the programmer intended.
Work around the problem by forcing the linker to fail if there are
any undefined symbols in the final object(s).

If we want to trap NULL vma's, we'd better be sure
that we don't dereference it first..

Lots of occurences of the same bug..

From: Meelis Roos <mroos@linux.ee>

This is self-explanatory - former SunDisk renamed itself to SanDisk and
now there are flash disks with both names.

 - we could pass MS_ACTIVE in mount flags and it would be passed into
   ->get_sb(), leading to interesting failure modes.  This flag is only
   for internal use (it's set once fill_super is complete and reset
   before the inode eviction on umount); made sure that we never get
   tricked into having it set it too early.

 - a bunch of filesystems force MS_NODIRATIME on mount but forgot to do
   the same on remount.  Fixed.

 - a bunch of r/o filesystems did force MS_RDONLY on mount but forgot to
   do the same on remount.  Fixed.

 - jff2->remount_fs() was buggy - it played with sb->s_flags instead of
   doing modifications to *flags (->s_flags will be overwritten using
   *flags right after the call of ->remount_fs()).  Moreover, it tried
   to do the wrong thing - it should just enforce noatime and be done
   with that.  Fixed, ACKed by maintainer.

 - we should force noatime both on mount and remount.  Fixed.

 - same problem as with sysv - mount-time checks for fs being good for
   writing are absent on remount.  Check added.

 - several variants of sysv fs are supported only r/o.  Driver does
   force r/o on mount, but doesn't do anything on remount.  As the
   result, one can remount them r/w and results are Not Pretty(tm).
   Missing checks added, code cleaned up. 

 - we had double-brelse() in v7fs - if sanity checks on root inode will
   succeed, but allocation of root dentry fails, we brelse() the same
   buffer_head twice.  Fixed.

The low level kernel interface to RTAS (the firmware runtime services)
was plagued with races that could cause from bogus results of RTAS
operations to total machine crashes in some circumstances. This patch
fix the ones I could identify, hoping I didn't miss any. I also added
a WARN_ON (well, it's asm equivalent) to enter_rtas to make sure we
never _ever_ try to call that with interrupts enabled.

This fix comes from ppc32. Always initialise dn->type and dn->name so
that code doesnt have to check for NULL everywhere. There is at least
one bug report where we oopsed because of this.

We have been debugging some strange fails where we branch to 0 in real
mode. At the moment this results in the cpu running through the
initialisation code and failing somewhere well into it.

The following patch uses the featuring nop'ing code to remove the branch
at real address 0 so it falls through to a trap instruction and gets
caught early.

This adda nmi_watchdog=2 support to the Pentium M processor.  The P-M is
a P6 chip, but it shares some chipset logic with the Pentium 4, so it
requires this workaround to function.

Without this patch, NMI gets stuck after 1 count.  With it, the NMI
fires and breaks me out of UHCI-related hard lockups. 

This patch is basically a modified version of the same patch for
oprofile. See the threaded discussion here:
