Merge branch 'for-linus-3.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rw/uml
Pull UML changes from Richard Weinberger:
"Mostly bug fixes and cleanups"
* 'for-linus-3.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rw/uml: (35 commits)
um: Update defconfig
um: Switch to large mcmodel on x86_64
MTD: Relax dependencies
um: Wire CONFIG_GENERIC_IO up
um: Serve io_remap_pfn_range()
Introduce CONFIG_GENERIC_IO
um: allow SUBARCH=x86
um: most of the SUBARCH uses can be killed
um: deadlock in line_write_interrupt()
um: don't bother trying to rebuild CHECKFLAGS for USER_OBJS
um: use the right ifdef around exports in user_syms.c
um: a bunch of headers can be killed by using generic-y
um: ptrace-generic.h doesn't need user.h
um: kill HOST_TASK_PID
um: remove pointless include of asm/fixmap.h from asm/pgtable.h
um: asm-offsets.h might as well come from underlying arch...
um: merge processor_{32,64}.h a bit...
um: switch close_chan() to struct line
um: race fix: initialize delayed_work *before* registering IRQ
um: line->have_irq is never checked...
...
