* um: fix gcov build breakageAl Viro2011-11-02
| | | | | | | | | a) exports in gmon_syms.c duplicate kernel/gcov/* ones b) excluding -pg in vdso compile is not enough - -fprofile-arcs and -ftest-coverage also needs to be excluded Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Richard Weinberger <richard@nod.at>
* um: page_offset.h is never usedAl Viro2011-11-02
| | | | | | | ... and neither is the only define in it Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> 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.

| | | | | | | | analog of [PATCH] i386: let usermode execute the "enter" instruction from circa 2006. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Richard Weinberger <richard@nod.at>

* um: merge os-Linux/tls.c into arch/x86/um/os-Linux/tls.cAl Viro2011-11-02
| | | | | | | | | 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>
* um: move asm/desc.h into arch/x86/um/asmAl Viro2011-11-02

* um: finish conversion to mcontext_tAl Viro2011-11-02

| | | | | Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Richard Weinberger <richard@nod.at>
* 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).

* um: don't bother blocking SIGARLM and SIGUSR1Al Viro2011-11-02
| | | | | | | | 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>
