      [PATCH] 4kstacks: fix compile with gcc 2.95 · 384278b0
      Dave Hansen authored 
      Investigation of why the build is failing due to bogus detection of
undefined symbols: We're getting this warning:

arch/i386/kernel/irq.c
{standard input}: Assembler messages:
{standard input}:3565: Warning: setting incorrect section type for
.bss.page_aligned

Which comes from this code in the 4k stacks code:

static char softirq_stack[NR_CPUS * THREAD_SIZE]  __attribute__((__aligned__(THREAD_SIZE), __section__(".bss.page_aligned")));
static char hardirq_stack[NR_CPUS * THREAD_SIZE]  __attribute__((__aligned__(THREAD_SIZE), __section__(".bss.page_aligned")));

Removing the __section__() fixes it, as does moving to gcc 3.2 or 3.3,
but gcc 2.95 and 3.0 still exhibit the problem.  It seems the 4k stack
developers like newer compilers than I do :) 

The gcc 2.95 section declaration looks like this:
	.section        .bss.page_aligned,"aw",@progbits
while the 3.1 section looks like this:
	.section        .bss.page_aligned,"aw",@nobits

It's definitely a bug that's been fixed:
http://sources.redhat.com/ml/binutils/2002-10/msg00507.html

I've been told that I can fix it with a carefully crafted assembly file and
maybe a change to the linker script, but all that it buys us is a little
space in the uncompressed kernel image.  Plus, the warning will still be
there at compile-time.  

I say, put them back in plain old BSS.

      [PATCH] via-rhine: Really call rhine_power_init() · 96ab2dec
      Roger Luethi authored 
      Without this patch, mainline via-rhine cannot wake the chip if some other
driver puts it to D3. The problem has hit quite a few people already.

This is a fix for the heisenbug with via-rhine refusing to work
sometimes. Patch "[9/9] Restructure reset code" contained a change made
necessary by patch [8/9]. Mainline merged [8/9] for 2.6.8 and is still
missing the fix, while -mm got it with [9/9].

Jesper Juhl provided crucial test data when no one else was able to
reproduce the symptoms.

      [PATCH] export kblockd_schedule_work() · 2cbbd9f3
      Jens Axboe authored 
      This is used by some IBM vscsi driver. It was using schedule_work(), but
should be using the block layer queue.
