This required fiddling the asm constraints of the atomic bitops. It
seems gcc isn't entirely happy with "+m": the manual says that the
'+' modifier should be used only when a register constraint is
available.

This simplifies the IRQ logic significantly and avoids the bogus
hvm_pic_assist() on domain resume path.
There is more work to be done here. At least:
1. set-irq-level should really be set-interrupt-wire-level. Wire
state needs to be distinguished from PIC (in particular, PIC IRR)
state.
2. Hypercalls can be batched in qemu and pushed down in one
multicall.

reads rsp_cons in do_block_io_op() with RING_FULL().

- remove magic number 8 and 64.
page size / sector size is 8 on x86, however on ia64 page size is
16kb.
blkring size is 64 on x86. however it's 128 on ia64.
- replace 0xFFFF with INVALID_GRANT_HANDLE
- don't map io ring into user space with uncachable.
kernel access the page with cacable and tapdisk uses memory barrier
so that it isn't necessary.
- remove printk warning and inserted new line.
- remove unused variable, page.
- add one BUG()

In multi-core and multi-threaded systems, not all idling "CPUs" are
equal: When there are idling execution vehicles, it's better to spread
VCPUs across sockets and cores before co-scheduling cores and threads.

This avoids a possible deadlock on the per-domain 'big lock'.
No control tools depend on synchronous halting of execution (e.g.,
save/restore already expect that secondary CPUs were halted
synchronously under the control of the guest itself). This makes the
code rather less complex.
