(which may sleep). Fix port-xen/29851 by YAMAMOTO Takashi.
Use config_pending_incr()/config_pending_decr() in if_xennet instead of
busy-looping (which doesn't work any more).
Remove the kernel thread from xbd, which isn't needed any more.
- Add FSSIOFSET and FSSIOFGET ioctl() to set/get the flags.
- Add FSS_UNCONFIG_ON_CLOSE flag to unconfigure the snapshot device
on the last close.

If extracting -s etc.tgz to a temporary directory, don't run the
embedded etc/postinstall since it doesn't exist anymore.
Remember the original SRC_DIR passed in (e.g, "-s etc.tgz") and
display that in the suggested "fix" message, rather than a temporary

systat and vmstat output more usable, especially as the channel numbers
change each time a guest reboots.
including soft interrupt, and this is way too low in some use (lots of domains,
or domains with lots of xennet, or even hardware with lots of devices at
different interrupts).
Based on idea from YAMAMOTO Takashi, keep one list of handler per-event and
one per-IPL (so the same handler is now in 2 lists). In the common case were
an event is received at low IPL, we can call the handlers quickly (there
is usually only one handler per event, unless the event is mapped to a
physical interrupt and this interrupt is shared by different devices).
Deffered events and software interrupts are handled by a bitmask (as before)
with one bit per IPL. When one IPL has an event pending all handlers for
this IPL will be called.
With this change, it is now possible to have all the 1024 events active.
While here, handle debug event in a special way: the handler is always called,
regardless of the current IPL. Make the handler print usefull informations
about events and IPL states.
Also remove code not used on Xen in files inherited from the x86 port.
and a number of sectors per track.
According to sys/fs/msdosfs/msdosfs_vfsops.c:msdosfs_mountfs(),
the kernel doesn't accept BPB with spt (sector per track) > 63
or hds (drive heads) > 255, so if values taken from disklabel
don't match these restrictions, use popular BIOS default values
(255/63) instead.

- distinguish paddr_t and bus_addr_t.
for xen, use bus_addr_t in the sense of machine address.
- move _X86_BUS_DMA_PRIVATE part of bus.h into bus_private.h.
- remove special handling of xen_shm. we can always grab
machine address from pte.
that a strictly conforming C program uses that name itself, so it had to
be removed. Also put the long comment above the #if 0, because it describes
the #if, not the isblank() macro. Added two blank lines to make the grouping
clear. Approved by kleink.
conversion to construct a quiet NaN on hppa, mips, sh3, and sh5 as well.
Also, remove the portion constructing a ROP on vax; this is not required
by the standard, and in its consequences it is not an appropriate
substitute for a qNaN.
distinction between signalling NaNs and quiet NaNs back into the
machine-dependent headers; treat the implementation of __nanf in the
same spirit.
IEEE 754 leaves the distinction between signalling NaNs and quiet NANs
to the implementation, and unlike our headers used to suggest they're
not identical in the interpretation of the fraction's MSb; in due
course, make those of hppa, mips, sh3, and sh5 reflect reality.
