x86: consolidate header guards

2008-07-22T19:31:34Z

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

xen64: implement 64-bit update_descriptor

2008-07-16T09:05:09Z

64-bit hypercall interface can pass a maddr in one argument rather than splitting it. Signed-off-by: Jeremy Fitzhardinge Cc: Stephen Tweedie Cc: Eduardo Habkost Cc: Mark McLoughlin Signed-off-by: Ingo Molnar

xen64: register callbacks in arch-independent way

2008-07-16T09:03:01Z

Use callback_op hypercall to register callbacks in a 32/64-bit independent way (64-bit doesn't need a code segment, but that detail is hidden in XEN_CALLBACK). Signed-off-by: Jeremy Fitzhardinge Cc: Stephen Tweedie Cc: Eduardo Habkost Cc: Mark McLoughlin Signed-off-by: Ingo Molnar

xen64: fix calls into hypercall page

2008-07-16T08:57:00Z

The 64-bit calling convention for hypercalls uses different registers from 32-bit. Annoyingly, gcc's asm syntax doesn't have a way to specify one of the extra numeric reigisters in a constraint, so we must use explicitly placed register variables. Given that we have to do it for some args, may as well do it for all. Also fix syntax gcc generates for the call instruction itself. We need a plain direct call, but the asm expansion which works on 32-bit generates a rip-relative addressing mode in 64-bit, which is treated as an indirect call. The alternative is to pass the hypercall page offset into the asm, and have it add it to the hypercall page start address to generate the call.

xen: fix 64-bit hypercall variants

2008-07-16T08:56:46Z

64-bit guests can pass 64-bit quantities in a single argument, so fix up the hypercalls. Signed-off-by: Jeremy Fitzhardinge Cc: Stephen Tweedie Cc: Eduardo Habkost Cc: Mark McLoughlin Signed-off-by: Ingo Molnar

xen: use new sched_op

2008-05-27T08:11:35Z

Use the new sched_op hypercall, mainly because xenner doesn't support the old one. Signed-off-by: Jeremy Fitzhardinge Signed-off-by: Thomas Gleixner

xen: use hypercall rather than clts

2008-05-27T08:11:35Z

Xen will trap and emulate clts, but its better to use a hypercall. Also, xenner doesn't handle clts. Signed-off-by: Jeremy Fitzhardinge Signed-off-by: Thomas Gleixner
