2010-02-19x86, pic: Make use of legacy_pic abstractionJacob Pan
This patch replaces legacy PIC-related global variable and functions with the new legacy_pic abstraction. Signed-off-by: Jacob Pan <jacob.jun.pan@intel.com> LKML-Reference: <43F901BD926A4E43B106BF17856F07559FB80D04@orsmsx508.amr.corp.intel.com> Signed-off-by: H. Peter Anvin <hpa@zytor.com>
2010-02-19x86, pic: Introduce legacy_pic abstractionJacob Pan
This patch makes i8259A like legacy programmable interrupt controller code into a driver so that legacy pic functions can be selected at runtime based on platform information, such as HW subarchitecure ID. Default structure of legacy_pic maintains the current code path for x86pc.

2009-04-10x86: move x86_quirk_pre_intr_init() to irqinit_32.cPekka Enberg
Impact: cleanup In preparation for unifying irqinit_{32,64}.c, make x86_quirk_pre_intr_init() local to irqinit_32.c. Reviewed-by Cyrill Gorcunov <gorcunov@openvz.org> Signed-off-by: Pekka Enberg <penberg@cs.helsinki.fi> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-02-23x86: refactor x86_quirks supportIngo Molnar
Impact: cleanup Make x86_quirks support more transparent. The highlevel methods are now named: extern void x86_quirk_pre_intr_init(void); extern void x86_quirk_intr_init(void); extern void x86_quirk_trap_init(void); extern void x86_quirk_pre_time_init(void); extern void x86_quirk_time_init(void); This makes it clear that if some platform extension has to do something here that it is considered ... weird, and is discouraged. Also remove arch_hooks.h and move it into setup.h (and other header files where appropriate). Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-10-22x86: Fix ASM_X86__ header guardsH. Peter Anvin
Change header guards named "ASM_X86__*" to "_ASM_X86_*" since: a. the double underscore is ugly and pointless. b. no leading underscore violates namespace constraints. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
