Some hardware (e.g. Dell Studio laptops) require special functions to
be called on physical cpu 0 in order to avoid occasional hangs. When
running as dom0 under Xen this could be achieved only via special boot
parameters (vcpu pinning) limiting the hypervisor in it's scheduling
decisions.
This pat
Add generic virtualization support for pinning the current vcpu to a
specified physical cpu. As this operation isn't performance critical
(a very limited set of operations like BIOS calls and SMIs is expected
to need this) just add a hypervisor specific indirection.

Some hardware models (e.g. Dell Studio 1555 laptops) require calls to
the firmware to be issued on cpu 0 only. As Dom0 might have to use
these calls, add xen_pin_vcpu() to achieve this functionality.
In case either the domain doesn't have the privilege to make the

Use smp_call_on_cpu() to raise SMI on cpu 0.

Do some cleanups in Mini-OS.
V2: modified patch 2 as suggested by Andrew Cooper
Juergen Gross (3):
mini-os: cleanup x86_32.S
mini-os: cleanup x86_64.S
mini-os: remove unused functions from sched.c
arch/x86/x86_32.S | 7 +--
arch/x86/x86_64.S | 43 +++--
arch/x86/x86_64.S contains some unnecessary macros. Remove them.
Add a SAVE_PARAVIRT macro for saving %rcx and %r11 on the stack in
case of CONFIG_PARAVIRT defined.
Remove the parameter from HYPERVISOR_IRET macro as it is used with
0 only.
