The former causes ICW1_RESET|ICW1_LTIM combination to be written to
control register, which on QEMU results in "level sensitive irq not

resource allocation on x86 platforms:
- Add a new helper API that Host-PCI bridge drivers can use to restrict
resource allocation requests to a set of address ranges for different
resource types.
- For the ACPI Host-PCI bridge driver, use Producer address range resources
in _CRS to enumerate valid address ranges for a given Host-PCI bridge.
This can be disabled by including "hostres" in the debug.acpi.disabled
tunable.
- For the MPTable Host-PCI bridge driver, use entries in the extended
MPTable to determine the valid address ranges for a given Host-PCI
bridge. This required adding code to parse extended table entries.
Similar to the new PCI-PCI bridge driver, these changes are only enabled
if the NEW_PCIB kernel option is enabled (which is enabled by default on
amd64 and i386).

Implement two previously-reserved Capsicum system calls:
- cap_new() creates a capability to wrap an existing file descriptor
- cap_getrights() queries the rights mask of a capability.

(typically fsck_ffs) to register that it wishes to use FFS specific
sysctl's to update the filesystem. This ensures that two checkers
cannot run on a given filesystem at the same time and that no other
process accidentally or maliciously uses the filesystem updating
sysctls inappropriately. This functionality is needed by the
journaling soft-updates recovery code.
Code to actually implement Capsicum capabilities, including fileops and
kern_capwrap(), which creates a capability to wrap an existing file
descriptor.
We also modify kern_close() and closef() to handle capabilities.
Finally, remove cap_filelist from struct capability, since we don't
actually need it.

As Garrett points out,
It is no more a debugging interface than setproctitle(3), and has not
been since the name started getting stuffed into the kernel. This
statement may have made sense when the name was only visible in thread
state dumps and the debugger.

flag (FS_SUJ) when determining whether to do journaling-based
operations. The mount flag is set only when journaling is active
while the superblock flag is set to indicate that journaling is to
be used. For example, when the filesystem is mounted read-only, the
journaling may be present (FS_SUJ) but not active (MNTK_SUJ).
Inappropriate checking of the FS_SUJ flag was causing some
journaling actions to be attempted at inappropriate times.

to announce driver specific offload capabilities to upper stack,
checksum offloading support needs more work and will be done in
future.
