At least one bin-utils version for ARM is know to ignore undefined
symbols when performing the final link of vmlinux.
Add an explicit check for undefined symbols to catch this.
The check is made in combination with generating the System.map file
and the actual algorithm is moved to a small shell script - mksysmap.

External symbols with three leading underscores are ignored - sparc
uses them for the BTFIXUP logic.

This code is a rework of the original Gladman AES code, and does not
include any supposed BSD licensed work by Jari Ruusu. 

Linus converted the Intel asm to Gas format, and made some minor
alterations.

Fruhwirth's glue module has also been retained, although I rebased the
table generation and key scheduling back to Gladman's code.  I've tested
this code with some standard FIPS test vectors, and large FTP transfers
over IPSec (both locally and over the wire to a system running the
generic AES implementation).

buffer without complaints.

*grrrrrrrr*

Wrong diff sent.  Sorry - normally the tree I'm working in is cp -rl'ed
from the -current, but right now it's a big mess.

This is the incremental fix.

This converts the 32-bit ppc htab code to use the seq_file interfaces.

Less code means fewer bugs..

This does the seq_file conversion + annotation + cleanup + race fixes
for arch/ppc64/kernel/rtas-proc.c.

How the fuck did that file manage to get anywhere near the tree, anyway?
Take a look at guy's "implementation" of sprintf(buf, "%04d", num), for
example:

<vomit>
	/* construct the sensor number like 0003 */
	/* fill with zeros */
	n = sprintf(tmp, "%d", s.token);
	len = strlen(tmp);
	while (strlen(tmp) < 4)
		n += sprintf (tmp+n, "0");

	/* invert the string */
	while (tmp[i]) {
		if (i<len)
			tmp2[4-len+i] = tmp[i];
		else
			tmp2[3-i] = tmp[i];
		i++;
	}
	tmp2[4] = '\0';
</vomit>

And it's full of that level of lusing ;-/

It would potentially remove dentries from the LRU list
without re-initializing the d_lru fields, causing later
accesses to that dentry to do bad things to the LRU list.

The following patch changes some 'unsigned long's into 'uint32_t's in
mktree (a program that runs on the host to frob the kernel image for
some firmwares).  Without it, the program is not correct when run
on/compiled on a 64bit host.

I just stumbled across this patch that's been sitting in my tree for ages.

I thought I'd sent this in before.  It's a trivial fix for the printing
of task state in /proc and sysrq dumps and such, so that TASK_DEAD shows
up correctly.  This state is pretty much only ever there to be seen when
there are exit/reaping bugs, but it's not like that hasn't come up.

Patch from Catalin Marinas

Gas translates the "msr [cs]psr, rN" instruction to "msr [cs]psr_cf, rN". This may cause problems on the ARMv6 architecture where the A and E bits can leak into the SVC mode from the USR mode via the exception handlers. The reverse can happen when returning to user mode. The patch adds _cxsf to all the msr instruction without the field specifier.

Patch from Catalin Marinas

The "err" is rotated in the blockops_check() function and all the error bits are cleared, the subsequent conditions being always true.

A number of drivers or special virtual devices really just want their
"read()" function to populate user space from some internal buffer.

This adds such a helper function - "simple_read_from_buffer()" - and
converts several ->read() instances to use it.

For requests marked read-ahead, it can legitimately fail without it being a
path problem.  So don't fail a path just because this happens (can be the
atomic request allocation going nuts, for instance), or all paths will

I tried to get multipathing failover running and failed. It seems to be
that there are two bugs in multipath.c :

- If a path/request fails mp_bh->path doesn't get updated to the new
  path.  Thus multipath_end_request will access a NULL pointer if a
  redirected request returns.

- After fixing this I experienced several other errors.  First of all in
  bio->bi_flags the BIO_UPTODATE flag is not set when redirecting a
  request.

  Causing the md driver to think that every redirected request failed
  when it returns.  Since that alone didn't fix the problems, I simply
  copied the master_bio again and it looks like everything seems to work.

On old powermacs, it's possible that we get a stale edge interrupt when
doing request_irq(), that typically happens with the DBDMA controller
interrupts when the device was used by the firmware for booting.

I just tracked down a nasty memory corruption problem where that was
causing the bmac driver to try to process packets before the driver
internal data structures were properly initialized.

While I agree that the driver should (and will) be made more robust to
such things, Paulus and I decided that it makes little sense to keep
track of an "old" edge interrupt that happens before a driver does
request_irq.  (On those powermacs, those are only the DBDMA interrupts
anyway, and none of the DBDMA users will care). 

This patch implements a "startup" handler for the old Apple PIC that
will "ack" pending edge interrupts before unmasking, thus preventing
those stale interrupts to be delivered.

It also "fixes" the ppc32 irq core to call the startup() callback when
available instead of just calling enable().

blk_rq_map_user() is a bit of a hack currently, since it drops back to
kmalloc() if bio_map_user() fails.  This is unfortunate since it means we
do no real segment or size checking (and the request segment counts contain
crap, already found one bug in a scsi lld).  It's also pretty nasty for >
PAGE_SIZE requests, as we attempt to do higher order page allocations.
Even worse still, ide-cd will drop back to PIO for non-sg/bio requests. 
All in all, very suboptimal.

This patch adds bio_copy_user() which simply sets up a bio with kernel
pages and copies data as needed for reads and writes.  It also changes
bio_map_user() to return an error pointer like bio_copy_user(), so we can
return something sane to the user instead of always -ENOMEM.
