the semantics in that the returned filename to use is now a kernel
pointer rather than a user space pointer. This required changing the
arguments to the CHECKALT*() macros some and changing the various system
calls that used pathnames to use the kern_foo() functions that can accept
kernel space filename pointers instead of calling the system call
directly.
- Use kern_open(), kern_access(), kern_msgctl(), kern_execve(),
kern_mkfifo(), kern_mknod(), kern_statfs(), kern_fstatfs(),
kern_setitimer(), kern_stat(), kern_lstat(), kern_fstat(), kern_utimes(),
kern_pathconf(), and kern_unlink().
duplicating the contents of the same functions inline.
- Consolidate common code to convert a BSD statfs struct to a Linux struct
into a static worker function.
structure in the struct pointed to by the 3rd argument for IPC_STAT and
get rid of the 4th argument. The old way returned a pointer into the
kernel array that the calling function would then access afterwards
without holding the appropriate locks and doing non-lock-safe things like
copyout() with the data anyways. This change removes that unsafeness and
resulting race conditions as well as simplifying the interface.
- Implement kern_foo wrappers for stat(), lstat(), fstat(), statfs(),
fstatfs(), and fhstatfs(). Use these wrappers to cut out a lot of
code duplication for freebsd4 and netbsd compatability system calls.
- Add a new lookup function kern_alternate_path() that looks up a filename
under an alternate prefix and determines which filename should be used.
This is basically a more general version of linux_emul_convpath() that
can be shared by all the ABIs thus allowing for further reduction of
code duplication.
reboot. Safter the reboot the TCC is usually in the Automatic mode, in which
reading current performance level is likely to produce bogus results make sure
to switch it to the On-Demand mode and set to some known performance level.
Unfortunately there is no reliable way to check that TCC is in the Automatic
mode. Reading bit 4 of ACPI Thermal Monitor Control Register produces 0
regardless of the current mode.

callout is first initialised, using a new function callout_init_mtx().
The callout system will acquire this mutex before calling the callout
function and release it on return.
In addition, the callout system uses the mutex to avoid most of the
complications and race conditions inherent in asynchronous timer
facilities, so mutex-protected callouts have much simpler semantics.
As long as the mutex is held when invoking callout_stop() or
callout_reset(), then these functions will guarantee that the callout
will be stopped, even if softclock() had already begun to process
the callout.
Existing Giant-locked callouts will automatically pick up the new
race-free semantics. This should close a number of race conditions
in the USB code and probably other areas of the kernel too.
There should be no change in behaviour for "MP-safe" callouts; these
still need to use the techniques mentioned in timeout(9) to avoid
race conditions.

resulting in a size_t due to C's rules of arithmetic. Rather than
bogusly cast the result to a uint8_t, fix the printf format specifier
to have a 'z' modifier which tells the compiler that the sizes really
do match.
It turns out that change 1.75 was incorrect to assume that this
'really' was a 8bit quantity. It isn't. Although the hardware
appears to limit things to < 256, it would be a bug that should be
caught by debug printf it it were. Casting it to uint8_t would have
lost this useful information.
Aslo add 'z' to a nearby debug statement that's never compiled in.
frequency as a percentage of the base rate and do not change the base
rate directly. The cpufreq framework combines these with absolute drivers
to produce synthesized levels made of one or more settings.
They have nothing at all to do with CIS parsing.
Remove some unused funce parsing: nothing used the results.
Use more of pccard_cis.h's deifnitions for the cardbus specific cis
parsing we do. More work is needed in this area.
This reduces the size of the cardbus module by 380 bytes or so...
doing it in the cpu driver. The previous code was incorrect anyway since
this value controls Px states, not throttling as the comment said. Since
we didn't support Px states before, there was no impact. Also, note that
we delay the write to SMI_CMD until after booting is complete since it
sometimes triggers a change in the frequency and we want to have all
drivers ready to detect/handle this.
- Bring IPsec support from the ports collection [1].
- Bring -o ("once only") option from the ports
collection [2].
- Adopt the Makefile framework into
usr.bin/nc/Makefile.
- Add a knob to control whether to build nc(1),
NO_NETCAT.
- Bump __FreeBSD_version so ports collection can
detect this change.
