2009-02-05x86: style cleanups for xen assembliesTejun Heo
Make the following style cleanups: * drop unnecessary //#include from xen-asm_32.S * compulsive adding of space after comma * reformat multiline comments Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-02-04xen: make direct versions of irq_enable/disable/save/restore to common codeJeremy Fitzhardinge
Now that x86-64 has directly accessible percpu variables, it can also implement the direct versions of these operations, which operate on a vcpu_info structure directly embedded in the percpu area. In fact, the 64-bit versions are more or less identical, and so can be shared. The only two differences are: 1. xen_restore_fl_direct takes its argument in eax on 32-bit, and rdi on 64-bit. Unfortunately it isn't possible to directly refer to the 2nd lsb of rdi directly (as you can with %ah), so the code isn't quite as dense. 2. check_events needs to variants to save different registers.

2008-07-31xen: compile irq functions without -pg for ftraceJeremy Fitzhardinge
For some reason I managed to miss a bunch of irq-related functions which also need to be compiled without -pg when using ftrace. This patch moves them into their own file, and starts a cleanup process I've been meaning to do anyway.
