x86: consolidate header guards 2008-07-22T19:31:34+00:00 Vegard Nossum vegard.nossum@gmail.com 2008-06-18T15:08:48+00:00 77ef50a522717fa040636ee1017179ceba12ff62 This patch is the result of an automatic script that consolidates the format of all the headers in include/asm-x86/. The format: 1. No leading underscore. Names with leading underscores are reserved. 2. Pathname components are separated by two underscores. So we can distinguish between mm_types.h and mm/types.h. 3. Everything except letters and numbers are turned into single underscores. Signed-off-by: Vegard Nossum <vegard.nossum@gmail.com>

x86_64: further cleanup of 32-bit compat syscall mechanisms 2008-07-16T09:08:27+00:00 Jeremy Fitzhardinge jeremy@goop.org 2008-07-12T09:22:00+00:00 6a52e4b1cddd90fbfde8fb67021657936ee74b07 AMD only supports "syscall" from 32-bit compat usermode. Intel and Centaur(?) only support "sysenter" from 32-bit compat usermode. Set the X86 feature bits accordingly, and set up the vdso in accordance with those bits. On the offchance we run on in a 64-bit environment which supports neither syscall nor sysenter from 32-bit mode, then fall back to the int $0x80 vdso.

x86 vDSO: use vdso-syms.lds 2008-01-30T12:30:41+00:00 Roland McGrath roland@redhat.com 2008-01-30T12:30:41+00:00 7f3646aa16f496201e045183402c6614fa27b0c7 This patch changes the kernel's references to addresses in the vDSO image to be based on the symbols defined by vdso-syms.lds instead of the old vdso-syms.o symbols. This is all wrapped up in a macro defined by the new asm-x86/vdso.h header; that's the only place in the kernel source that has to know the details of the scheme for getting vDSO symbol values.
