- sysctl dev.acpi_hp.0.verbose to toggle debug output
- A modification so this can deal with different array lengths
when reading the CMI BIOS - now it works ok on HP Compaq nx7300
as well.
- Change behaviour to query only max_instance-1 CMI BIOS instances,
because all HPs seen so far are broken in that respect
(or there is a fundamental misunderstanding on my side, possible
as well). This way a disturbing ACPI Error Field exceeds Buffer
message is avoided.
- New bit to set on dev.acpi_hp.0.cmi_detail (0x8) to
also query the highest guid instance of CMI bios
acpi_hp.4:
- Document dev.acpi_hp.0.verbose sysctl in man page
- Document new bit for dev.acpi_hp.0.cmi_detail
- Add a section to manpage about hardware that has been reported
to work ok

- Centralize generation of argument tokens for VM addresses in a macro,
ADDR_TOKEN(), and properly encode 64-bit addresses in 64-bit arguments.
- Fix up argument numbers across a large number of syscalls so that they
match the numeric argument into the system call.
- Don't audit the address argument to ioctl(2) or ptrace(2), but do keep
generating tokens for mmap(2), minherit(2), since they relate to passing
object access across execve(2).

- For x86, change the interrupt source method to assign an interrupt source
to a specific CPU to return an error value instead of void, thus allowing
it to fail.
- If moving an interrupt to a CPU fails due to a lack of IDT vectors in the
destination CPU, fail the request with ENOSPC rather than panicing.
- For MSI interrupts on x86 (but not MSI-X), only allow cpuset to be used
on the first interrupt in a group. Moving the first interrupt in a group
moves the entire group.
- Use the icu_lock to protect intr_next_cpu() on x86 instead of the
intr_table_lock to fix a LOR introduced in the last set of MSI changes.
- Add a new privilege PRIV_SCHED_CPUSET_INTR for using cpuset with
interrupts. Previously, binding an interrupt to a CPU only performed a
privilege check if the interrupt had an interrupt thread. Interrupts
without a thread could be bound by non-root users as a result.
- If an interrupt event's assign_cpu method fails, then restore the original
cpuset mask for the associated interrupt thread.

call could get hung sleeping on "gsssta" if the credentials for a user
that had been accessing the mount point have expired. This happened
because rpc_gss_destroy_context() would end up calling itself when the
"destroy context" RPC was attempted, trying to refresh the credentials.
This patch just checks for this case in rpc_gss_refresh() and returns
without attempting the refresh, which avoids the recursive call to
rpc_gss_destroy_context() and the subsequent hang.

is identical to the mode computed from that ACL will modify the ACL.
For example, mode computed from the following ACL is 0600:
user:kamila:rwx--------C--:------:allow
owner@:--x-----------:------:deny
owner@:rw-p---A-W-Co-:------:allow
group@:rwxp----------:------:deny
group@:--------------:------:allow
everyone@:rwxp---A-W-Co-:------:deny
everyone@:------a-R-c--s:------:allow
However, applying that mode (chmod 0600) changes the ACL into this:
user:kamila:rwx-----------:------:deny
user:kamila:rwx--------C--:------:allow
owner@:--x-----------:------:deny
owner@:rw-p---A-W-Co-:------:allow
group@:rwxp----------:------:deny
group@:--------------:------:allow
everyone@:rwxp---A-W-Co-:------:deny
everyone@:------a-R-c--s:------:allow
In chmod(1) utility, there is an optimisation, which makes it not
call chmod(2) if the mode of the file is the same as the new mode.
Disable that optimisation for files which may have NFSv4 ACLs.

calls treat the data field of the argument struct passed as a mask
and set/clear bits of the MSR register according to the mask value.
- Allow user to perform atomic bitwise AND and OR operaions on MSR registers
via cpucontrol(8) utility. Two new operations ("&=" and "|=") have been
added. The first one applies bitwise AND operaion between the current
contents of the MSR register and the mask, and the second performs bitwise
OR. The argument can be optionally prefixed with "~" inversion operator.
This allows one to mimic the "clear bit" behavior by using the command
like this:
cpucontrol -m 0x10&=~0x02 # clear the second bit of TSC MSR
Inversion operator support in all modes (assignment, OR, AND).
