unw_step(). Both errors denote the end of a stack trace (i.e. no
prior frame), but are otherwise not error conditions.
Have db_trace() return 0 when the trace ends due to one of these
return codes as they are really normal termination conditions.
This change especially improves the output of the "show thread"
command in DDB when there are threads in fork_trampoline() and
previously db_trace() would return an error, causing the show
command to emit '***'.
- Split core DRM routines back into their own module, rather than using the
nasty templated system like before.
- Development-class R300 support in radeon driver (requires userland pieces, of
course).
- Mach64 driver (haven't tested in a while -- my mach64s no longer fit in the
testbox). Covers Rage Pros, Rage Mobility P/M, Rage XL, and some others.
- i915 driver files, which just need to get drm_drv.c fixed to allow attachment
to the drmsub device. Covers i830 through i915 integrated graphics.
- savage driver files, which should require minimal changes to work. Covers the
Savage3D, Savage IX/MX, Savage 4, ProSavage.
- Support for color and texture tiling and HyperZ features of Radeon.

than WIN_CHARS bytes, we shift the suffix (previous substrings) upwards
by the amount this substring exceeds its WIN_CHARS slot. Profiling shows
this change is indistinguishable from the previous code at 95% confidence.
This bug would result in attempts to access or create files or directories
with multi-byte characters returning an error but no data loss.

of physical addresses. The pages containing these physical addresses will
not be added to the free list and thus will effectively be ignored by the
VM system. This is mostly useful for the case when one knows of specific
physical addresses that have bit errors (such as from a memtest run) so
that one can blacklist the bad pages while waiting for the new sticks of
RAM to arrive. The physical addresses of any ignored pages are listed in
the message buffer as well.
- Move the description of the ``-c string'' option closer to the option itself.
- Add an ENVIRONMENT section (1)
- Add more .Xr cross references to the SEE ALSO section.

This allows to attach to the children (ATA devices) even without a
driver being attached. This allows atapi-cam to do its work both
with and without the pure ATAPI driver being present.

save the value first then it can be clobbered if an interrupt comes in

Specifically, if the BIOS has programmed an IRQ for a device that doesn't
match the list of valid IRQs for the link, use it anyway as some BIOSes
don't correctly list the valid IRQs in the $PIR. Also, allow the user
to specify an IRQ that $PIR claims is invalid as an override, but emit a
warning in that case.
when using an APIC. This simplifies the APIC code somewhat and also allows
us to be pedantically more compliant with ACPI which mandates no use of
mixed mode.
printf's during a verbose boot is more intuitive (the BAR listings and
interrupt routing info now comes after the config header dump rather than
just before it).
MAP_SHARED so that the entry point gets executed un-conditionally.
This may be useful for security policies which want to perform access
control checks around run-time linking.
-add the mmap(2) flags argument to the check_vnode_mmap entry point
so that we can make access control decisions based on the type of
mapped object.
-update any dependent API around this parameter addition such as
function prototype modifications, entry point parameter additions
and the inclusion of sys/mman.h header file.
-Change the MLS, BIBA and LOMAC security policies so that subject
domination routines are not executed unless the type of mapping is
shared. This is done to maintain compatibility between the old
vm_mmap_vnode(9) and these policies.

Save a memory dereference in the ISR by passing this in directly.
Calling pps_capture is MP safe for all other operations on struct
pps_state, so there's no need to aquire the lock before we do this,
even from a fast ISR. Avoid dereferencing sc->ppbus until after
pps_capture is called as well. These actions reduce somewhat the
cache effects that cause variance in interrupt times. On an
especially slow test machine (300MHz Cyrix GXm), this reduces the
interrupt latency about about 10% (from 21us to 19us) and helps a
little with the variance (although most of the variance seems to be
caused by lots of interrupt masking).
This also happens fixes one or two of bde's style issues.
