currently the hypervisor vga cache (stdvga.c) enables itself only in
graphical mode and in the a0000h-affffh range. However there is no
reason for this: it already allocates enought memory to map the whole
vram. I am attaching a patch that implements the bank switching
mechanism in stdvga.c, allowing the cache to be always enabled when
the emulated graphic card is in VGA mode.

This adds a new HVM op that enables tracking dirty bits of a range of
video RAM. The idea is to optimize just for the most common case
(only one guest mapping, with sometimes some temporary other
mappings), which permits to keep the overhead on shadow as low as
possible.

When sdl_resize resizes the SDL window, some window manager send back
a ConfigureNotify event, which triggers a SDL_VIDEORESIZE event. That
event, however, is seen only much later, on the next VGA refresh
round. If the guest quickly switches to another resolution in between,
the SDL_VIDEORESIZE event makes us erroneously rescale that new
resolution into the old one.
This patch makes us pump that window manager event, so that no
SDL_VIDEORESIZE event is generated.

This depends on how __uid_t is defined in the system header.
No file under the zfs directory uses uid_t so that just removing
the definition in the zfs_acl.h looks reasonable.

In the xc_translate_foreign_address function from libxc, there is a
check on the page directory entry to see if the page is 4K or 4M.
However, the check is looking at bit 3, when it should be looking at
bit 7. This patch fixes the problem.

Solaris uses a simple indexing scheme for block devices. Parts of xend
translate them as hexadecimal (such as block-attach), and decimal, or
unconverted, elsewhere (such as block-detach). Harmonise these
interfaces by allowing decimal specifications.
Also allow Solaris-style block device names.

C3 & deep C state will need to do ARB_DIS or cache flush. ARB_DIS
should be done within the last cpu which is ready for C3. Bus master
activities are checked and recorded for C state promotion/demotion
judgement.
C3 is disabled by default, till TSC/APIC stop issues resolved.
Adding cmdline option "max_cstate=3" can enable C3.
