sigio_lock is taken both from process context and from interrupt context. So we
*must* use irqsave.
Then, remove irq disabling from update_thread(), as it's called with

Comment the fact that sig_info is initialized early in boot, and thus doesn't
need any locking.

Include linux/types.h here because we need a definition of __u32. This file

ACK on all of these except for 1, which won't apply to current -mm,
and 4, which might need some more work.

The code which you're changing here is gone in current -mm.
Hi Andrew, I've been resurrecting lately remap_file_pages protection support
for UML.
I've updated it to 2.6.20 and it passes its unit test, and the
resulting kernel has no stability problems in my experience on my Dual Core
laptop (I've been using it for long time).
Since last time I sent it,

This may be considered useless, but YMMV. I consider that this has a limited
security value, exactly like disabling module support (in many case it is
useful).

I've seen UML 2.6.21-rc crashing at boot due to CONFIG_DEBUG_SHIRQ. Below I've
written the diagnosis, without a resolution.
The problem is in mconsole_init() with CONFIG_DEBUG_SHIRQ - it registers the
mconsole IRQ. CONFIG_DEBUG_SHIRQ triggers a fake IRQ at registration time, to
catch device dri
