2018-10-31treewide: remove current_text_addrNick Desaulniers
Prefer _THIS_IP_ defined in linux/kernel.h. Most definitions of current_text_addr were the same as _THIS_IP_, but a few archs had inline assembly instead. This patch removes the final call site of current_text_addr, making all of the definitions dead code.

2013-11-17um: Rewrite show_stack()Richard Weinberger
Currently on UML stack traces are not very reliable and both x86 and x86_64 have their on implementations. This patch unifies both and adds support to outline unreliable functions calls. Signed-off-by: Richard Weinberger <richard@nod.at>

2011-11-02um: take ldt.h to arch/x86/um/asm/mm_context.hAl Viro
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.
