Linux v2.5.48

Linux v2.5.48

[Linus Torvalds]

Hmm.. All over the place, best you see the changelog. Lots of small 
cleanups (remove unnecessary header files etc), but a few more fundamental 
changes too. Times in nsecs in stat64(), for example, and the 
oft-discussed kernel module loader changes..

		Linus


Summary of changes from v2.5.47 to v2.5.48

To get this to load modules, you need:
http://www.kernel.org/pub/linux/kernel/people/rusty/module-init-tools-0.7.tar.gz

Just to save you the searching.

Shameless plug: to play with the ipsec, see
http://lartc.org/howto/lartc.ipsec.html - should now work without further
patches!

This oopses on NUMA-Q sometime prior to TSC synch and then hangs in TSC
synch because not all cpus are responding where 2.5.47-mm3 (which
included some intermediate bk stuff) did not. This is because AP's are
taking timer interrupts before they are prepared to do so. Please apply
the following patch from Martin Bligh which resolves this issue:

Actually, please apply this one instead. The prior patch did not

It seems to come and go randomly (timing issue), it's not new with 48. 
Has been happening since 44-mm3 or so. Just as a point of interest,
doesn't seem to be the timer int itself that kill her, it's the 
softirq processing that happens in irq_exit on the way back.

This is all the more ammunition for the patch's inclusion. Linus, this
problem is even more severe and more persistent than I originally reported.


Please apply.

This patch broke the compilation of dv1394:

<--  snip  -->

...
  gcc -Wp,-MD,drivers/ieee1394/.dv1394.o.d -D__KERNEL__ -Iinclude -Wall
-Wstrict-prototypes -Wno-trigraphs -O2 -fomit-frame-pointer

The fix is trivial:

If module support is enabled, the thing links beautifully.

Ok, this should be fixed in current -bk (snapshots will be built at 4AM 
PST as usual, so they should show up reasonably soon).

I also merged/updated the old kallsyms fixups from Rusty, so together with
the updated module loader we should be back to "working order" both
without and with modules and not missing any features.

Please test,

Does this then make depmod happy?

Without it I get heaps of (eg)
depmod: *** Unresolved symbols in /lib/modules/2.5.48/kernel/zlib_deflate.o

I tried applying Adam Richter's module device ID tables patch without success.


#
# Loadable module support
#
CONFIG_MODULES=y
# CONFIG_MODULE_UNLOAD is not set
# CONFIG_MODULE_FORCE_UNLOAD is not set
CONFIG_KMOD=y

Turning off KMOD, or turning on UNLOAD makes no difference.

depmod version 2.4.18  I tried the latest 2.4.21 as well.

Hi Adrian,

That's a gcc extension that means the same as your patch.  See
http://gcc.gnu.org/onlinedocs/gcc-3.2/gcc/Conditionals.html#Conditionals

It would be OK with me not to accept such extensions.  :)

Hello!

One of a few of extensions which does not cause any reaction
but "it's strange that it was not in KR, apparently it was lost
due to a buglet in the first parser" :-)

Ah, thanks for the correction. I didn't know that there is such a gcc
extension.
