2008-07-22x86: consolidate header guardsVegard Nossum1-3/+3
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>
2008-07-16xen64: implement 64-bit update_descriptorJeremy Fitzhardinge1-4/+9
64-bit hypercall interface can pass a maddr in one argument rather than splitting it.

2008-07-16xen64: register callbacks in arch-independent wayJeremy Fitzhardinge1-0/+12
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).

2008-07-16xen64: fix calls into hypercall pageJeremy Fitzhardinge1-48/+122
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.

2008-07-16xen: fix 64-bit hypercall variantsJeremy Fitzhardinge1-29/+31
64-bit guests can pass 64-bit quantities in a single argument, so fix up the hypercalls.

2008-05-27xen: use new sched_opJeremy Fitzhardinge1-2/+2
Use the new sched_op hypercall, mainly because xenner doesn't support the old one. Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2008-05-27xen: use hypercall rather than cltsJeremy Fitzhardinge1-0/+7
Xen will trap and emulate clts, but its better to use a hypercall. Also, xenner doesn't handle clts. Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
