2011-11-02um: irq_vectors.h just shadows x86 oneAl Viro1-0/+0

2011-11-02um: required-features.h is there only to shadow x86 one...Al Viro1-0/+0

2011-11-02um: asm/apic.h is there only to shadow the x86 one...Al Viro1-0/+0
... so take it to arch/um/x86/asm. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Richard Weinberger <richard@nod.at>

2011-11-02um: take ldt.h to arch/x86/um/asm/mm_context.hAl Viro6-61/+58
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.

2011-11-02um: merge os-Linux/tls.c into arch/x86/um/os-Linux/tls.cAl Viro5-43/+38
it's i386-specific; moreover, analogs on other targets have incompatible interface - PTRACE_GET_THREAD_AREA does exist elsewhere, but struct user_desc does *not* Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Richard Weinberger <richard@nod.at>
2011-11-02um: move asm/desc.h into arch/x86/um/asmAl Viro1-0/+0

2011-11-02um: finish conversion to mcontext_tAl Viro9-81/+67
now we don't mix host and guest signal frame layouts anymore; moreover, we don't need host's struct sigcontext at all. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Richard Weinberger <richard@nod.at>

2011-11-02um: simplify set_handler()Al Viro4-27/+19
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).

2011-11-02um: don't bother blocking SIGARLM and SIGUSR1Al Viro3-9/+8
We used to generate those, but we hadn't done that for a long time. No need to bother blocking them for signal handlers. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Richard Weinberger <richard@nod.at>
