I run an x86_64 kernel with i386 userspace (Ubuntu Dapper) and decided to try
out UML today. I found that UML wasn't quite aware of biarch compilers (which
Ubuntu i386 ships). A fix similar to what was done for x86_64 should probably
be committed (see
http://marc.theaimsgroup.com/?l=linux-kernel&m=113425940204010&w=2). Without
the FLAGS changes, the build will fail at a number of places and without the
LINK change, the final link will fail.

-mm in combination with an FC5 init started dying with 'stderr=1' because init
didn't like the lack of /dev/console and exited. The problem was that the
stderr console, which is intended to dump printk output to the terminal before
the regular console is initialized, isn't a tty, and so can't make
/dev/console operational.
However, since it is registered first, the normal console, when it is
registered, doesn't become the preferred console, and isn't attached to
/dev/console. Thus, /dev/console is never operational.
This patch makes the stderr console unregister itself in an initcall, which is
late enough that the normal console is registered. When that happens, the
normal console will become the preferred console and will be able to run
/dev/console.

This patch-queue improves the generic IRQ layer to be truly generic, by adding
various abstractions and features to it, without impacting existing
functionality.
While the queue can be best described as "fix and improve everything in the
generic IRQ layer that we could think of", and thus it consists of many
smaller features and lots of cleanups, the one feature that stands out most is
the new 'irq chip' abstraction.
The irq-chip abstraction is about describing and coding and IRQ controller
driver by mapping its raw hardware capabilities [and quirks, if needed] in a
straightforward way, without having to think about "IRQ flow"
(level/edge/etc.) type of details.
This stands in contrast with the current 'irq-type' model of genirq
architectures, which 'mixes' raw hardware capabilities with 'flow' details.
The patchset supports both types of irq controller designs at once, and
converts i386 and x86_64 to the new irq-chip design.
As a bonus side-effect of the irq-chip approach, chained interrupt controllers
(master/slave PIC constructs, etc.) are now supported by design as well.
The end result of this patchset intends to be simpler architecture-level code
and more consolidation between architectures.
We reused many bits of code and many concepts from Russell King's ARM IRQ
layer, the merging of which was one of the motivations for this patchset.
This patch:
rename desc->handler to desc->chip.
Originally i did not want to do this, because it's a big patch. But having
both "desc->handler", "desc->handle_irq" and "action->handler" caused a
large degree of confusion and made the code appear alot less clean than it
truly is.
I have also attempted a dual approach as well by introducing a
desc->chip alias - but that just wasnt robust enough and broke
frequently.
So lets get over with this quickly. The conversion was done automatically
via scripts and converts all the code in the kernel.
This renaming patch is the first one amongst the patches, so that the
remaining patches can stay flexible and can be merged and split up
without having some big monolithic patch act as a merge barrier.

*) Rather than duplicate in various buggy ways the application of
CFLAGS_NO_HARDENING and UNPROFILE (which apply to the same files),
centralize it in Makefile.rules. UNPROFILE_OBJS mustn't be listed in
USER_OBJS but are compiled as such.
I've also verified that unprofile didn't work in the current form, because we
set _c_flags directly (using CFLAGS and not USER_CFLAGS, which is wrong),
which is normally used by c_flags, but we also override c_flags for all
USER_OBJS, and there we don't call unprofile.
Instead it only worked for unmap.o, the only one which wasn't a USER_OBJ.
We need to set c_flags (which is not a public Kbuild API) to clear a lot of
compilation flags like -nostdinc which Kbuild forces on everything.
*) Rather than $(CFLAGS_$(notdir $@)), which expands to CFLAGS_anObj.s when
building "anObj.s", use $(CFLAGS_$(*F).o) which always accesses
CFLAGS_anObj.o, like done by Kbuild.
*) Make c_flags apply to all targets having the same basename, rather than
listing .s, .i, .lst and .o, with the use (which I tested) of
$(USER_OBJS:.o=.%): c_flags = ...
and of
- $(obj)/unmap.c: _c_flags = ...
+ $(obj)/unmap.%: _c_flags = ...

To make some half-assembly stubs compile, disable various "hardened" GCC
features:
*) we can't make it build PIC code as we need %ebx to do syscalls and GCC
wants it free for PIC
*) we can't leave stack protection as the stub is moved (not relocated!) in
memory so the RIP-relative access to the canary tries reading from an
unmapped address and causes a segfault, since we move the stub of various
megabytes (the exact amount will be decided at runtime) away from the
link-time address.
