| * Remove all #inclusions of asm/system.hDavid Howells2012-03-28
| | | | | | | | | | | | | | | | | | Remove all #inclusions of asm/system.h preparatory to splitting and killing it. Performed with the following command: perl -p -i -e 's!^#\s*include\s*<asm/system[.]h>.*\n!!' `grep -Irl '^#\s*include\s*<asm/system[.]h>' *` Signed-off-by: David Howells <dhowells@redhat.com>

| * um: Serve io_remap_pfn_range()Richard Weinberger2012-03-24
| | | | | | | | | | | | | | At some places io_remap_pfn_range() is needed. UML has to serve it like all other archs do. Signed-off-by: Richard Weinberger <richard@nod.at>

* um: take ldt.h to arch/x86/um/asm/mm_context.hAl Viro2011-11-02
| | | | | | | | | | | | | | | it's x86-only and we have no business playing with it in asm/mmu.h; make the latter have struct uml_arch_mm_context arch; instead of struct uml_ldt ldt; and let arch/<subarch>/um/asm/mm_context.h decide what'll be in there. While we are at it, kill host_ldt.h - it's not needed in part of places that include it (we want asm/ldt.h in those) and it can be trivially expanded into the single remaining one.

* um: simplify set_handler()Al Viro2011-11-02
| | | | | | | | | | For one thing, we always block the same signals (IRQ ones - IO, WINCH, VTALRM), so there's no need to pass sa_mask elements in arguments. For another, the flags depend only on whether it's an IRQ signal or not (we add SA_RESTART for them).
