Revert r5636 to fix icount on hosts w/o high-res clocks
Changeset r5636 changed the timers to run in the alarm callback. The
alarm callback can only be called as frequently as the host alarm timer
fires. For older Linux hosts and possibly non-Linux hosts, this can be
as high as a 1ms granularity.
icount calculates the select timeout based on the next deadline and
select is usually capable of sleeping for a short period of time than
alarm timer granularity. This means that changing the timer callbacks
to be based on alarm firing caused timers to fire much later than they
ought to when using icount.

e1000 VLAN offload emulation (Alex Williamson)
We're currently ignoring the e1000 VLAN tagging, stripping and filtering
features in the e1000 emulation. This patch adds backing for the
relevant registers and provides a software implementation of the
acceleration, such that a guest can make use of VLANs.
This is mostly (only?) useful for a guest on a bridge (not user mode
networking). The only caveat beyond that is that you need to make sure
the host NIC isn't doing it's own tagging, stripping, or filtering.
This generally means the host NIC on the bridge should not be part of a

This patch tweaks the ATAPI CDROM emulation to fix an annoyance seen
when running a variety of Linux guests: the desktop GUI shows a CDROM

The patch adds the PLAY_AUDIO capability bit to the data returned by
MODE_SENSE commands. That convinces the guest kernel to determine what
kind of media is present.
Arguably Linux could be smarter about this, but it's my guess there are

On breakpoint hit, the focus is automatically adjusted just as for

Furthermore, the patch propagates breakpoint and watchpoint insertions

Make KVM slot management more robust
KVM keeps track of physical memory based on slots in the kernel. The current
code that translates QEMU memory mappings to slots work but is not robust
in the fact of reregistering partial regions of memory.
This patch does the right thing for reregistering partial regions of memory. It
also prevents QEMU from using KVM private slots.

target-alpha: implement getxuid and getxgid syscalls
This patch implemented the setxuid and setxgid syscalls for Alpha.
These syscalls return two values, both uid/euid and gid/egid.
In addition to returning the first value in $v0, the additional
value is returned in the $a4 register.
The syscalls are used instead of the separate syscalls for those values
used on other architectures (this is probably because Alpha Linux started
out syscall compatible with DEC/OSF/Tru64).
With this patch, the perlbmk benchmarks from Spec2000 run properly.
