The recent fixes for the external module build have fixed the major
breakage, but they left one annoyance unfixed.  If CONFIG_MODVERSIONS is
disabled, a warning is printed for every exported symbol that is has no
CRC.  For instance, I see this when compiling the standalone Orinoco
driver on Linux 2.6.6-rc3:

*** Warning: "__orinoco_down" [/usr/local/src/orinoco/spectrum_cs.ko] has
no CRC!
*** Warning: "hermes_struct_init" [/usr/local/src/orinoco/spectrum_cs.ko]
has no CRC!
*** Warning: "free_orinocodev" [/usr/local/src/orinoco/spectrum_cs.ko] has
no CRC!
[further warnings skipped]

I have found that the "-i" option for modpost is used for external builds,
whereas the internal modules use "-o".  The "-i" option causes read_dump()
in modpost.c to be called.  This function sets "modversions" variable
under some conditions that I don't understand.  The comment before the
modversions declarations says: "Are we using CONFIG_MODVERSIONS?"

Apparently modpost fails to answer this question.  I think it's better to
use an explicit option rather than a kludge.

The attached patch adds a new option "-m" that is specified if and only if
CONFIG_MODVERSIONS is enabled.  The patch has been successfully tested
both with and without CONFIG_MODVERSIONS.

This patch teaches scripts/kernel-doc to print descriptions
of comma separated variables correctly instead of ignoring
them.

Shouldn't we be grepping __crc_ symbols out of the System.map file?

For one thing, these can confuse readprofile.  It's algorithm is
to start at _stext, then stop when it sees a line in the System.map
which is not text (mode is one of 'T' 't' 'W' or 'w')

It will exit early if there are some intermixed __crc_* things in
there (since they are are mode 'A').

For example, in my current sparc64 kernel I have this:

00000000004cef80 t do_split
00000000004cf2a0 t add_dirent_to_buf
00000000004cf5a7 A __crc_init_special_inode
00000000004cf640 t make_indexed_dir
00000000004cf900 t ext3_add_entry

So no symbols after add_dirent_to_buf will be shown in the profiling
output of readprofile.

Implementation ported to mksysmap by Sam.
Included two System.map related fixes:
- Print "SYSMAP  System.map" during build
- Sort symbols in System.map

When compiling Linux on Mac OSX I had trouble with scripts/sumversion.c.
It includes <netinet/in.h> to obtain to definitions of htonl and ntohl.

On Mac OSX these are found in <arpa/inet.h>. After checking the POSIX
specification it appears that this is the correct place to get
the definitons for these functions.

(http://www.opengroup.org/onlinepubs/009695399/functions/htonl.html)

Using this header also appears to work on Linux (at least with
Glibc-2.3.2).

It seems clearer to me to go with the POSIX standard than implementing
#if __APPLE__ style macros, but if such an approach is preferred I can
supply patches for that instead.

Introducing hostprogs-y allows a user to use the typical Kbuild
pattern in a Kbuild file:
hostprogs-$(CONFIG_KALLSYMS) += ...

And then during cleaning the referenced file are still deleted.
Deprecate the old host-progs assignment but kept the functionlity.

External modules will continue to use host-progs for a while - drawback is
that they now see a warning.
Workaround - just assign both variables:
hostprogs-y := foo
host-progs  := $(hostprogs-y)

All in-kernel users will be converted in next patch.

Concentrating all host-progs functionality in one file made a more

Peter Chubb <peterc@gelato.unsw.edu.au> reported that building i386
on a non-i386 platform failed, because gcc could not locate boot.h.
Root cause was the extra include2 directory used when using O=
to specify the output directory.
Added LINUXINCLUDE as a portable way to specify the include/
directory, and changed the two users.
This avoids hardcoding 'include2' in non-kbuild core files.

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
quickly go away.

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.
