with 0, and removes unnecessary page deallcation when destroying monitor
table. Without this patch, destroying hap domain will fail.

In functions set_eflags_* (xen/arch/x86/hvm/io.c), if the first
argument "size" equals sizeof(long), the following code will produce
unintended and invalid result:
unsigned long mask = (1 << (8 * size)) - 1;
In ANSI C, if the shift amount is greater or equal to the width of the
data type, the result is undefined. Specifically on x86, a bit mask is
applied to the shift amount, so that more significant bits are
ignored. So the above expression results 0x0 instead of the intended
~0UL.
This patch fixes this issue. Because size=0 is not a valid parameter,
rewriting the code using right shift avoids an additional condition
check.

them with atomic (locked) ops.
Conversion here isn't complete in the sense that many places still use
the old per-CPU accessors (which are now redundant). Since the patch
is already rather big, I'd prefer replacing those in a subsequent
patch.
While doing this, I also converted x86's multicall macros to no longer
require inclusion of asm-offsets.h in the respective C file (on IA64
the use of asm-offsets.h in C sources seems more wide spread, hence
there I rather used IA64_ prefixes for the otherwise conflicting
performance counter indices).
On x86, a few counter increments get moved a little, to avoid
duplicate counting of preempted hypercalls.
Also, a few counters are being added.
IA64 changes only compile-tested, hence somebody doing active IA64
work may want to have a close look at those changes.

A few more adjustments to when the 'big' lock is taken/dropped.
Also, fix a case where the foreign domain setting may not get properly
cleared at the end of a hypercall (in case of an early error).

The recent change to guest time handling dropped a call to
update_vcpu_system_time(), leading to time-went-backwards messages and
guest hangs (the latter were observed only in 2.6.21-rc4 and only when
no serial console was in use).
Debugging the issue also revealed that some commented out debug
printk-s in x86's time handling code didn't compile under x86-64.
