vm_page's machine-dependent fields. Use this function in
vm_pageq_add_new_page() so that the vm_page's machine-dependent and
machine-independent fields are initialized at the same time.
Remove code from pmap_init() for initializing the vm_page's
machine-dependent fields.
Remove stale comments from pmap_init().
Eliminate the Boolean variable pmap_initialized from the alpha, amd64,
i386, and ia64 pmap implementations. Its use is no longer required
because of the above changes and earlier changes that result in physical
memory that is being mapped at initialization time being mapped without
pv entries.

UFS by:
- Making the pre and post hooks for the VOP functions work even when
DEBUG_VFS_LOCKS is not defined.
- Moving the KNOTE activations into the corresponding VOP hooks.
- Creating a MNTK_NOKNOTE flag for the mnt_kern_flag field of struct
mount that permits filesystems to disable the new behavior.
- Creating a default VOP_KQFILTER function: vfs_kqfilter()
My benchmarks have not revealed any performance degradation.

- Restructured for easier extensibility and maintainability
- To be more uniform with the other ACPI extras drivers and to better reflect
their actual meaning, some sysctls were moved:
o brightness -> lcd_brightness
o keylight -> thinklight
o enable -> events
o misckey -> hotkey
o avail_mask -> availmask
o key_mask -> eventmask
- New "initialmask" sysctl, which holds the initial eventmask
- The "wlan" sysctl is now read-only, since writing to it didn't have
any effect
- The "version" sysctl was removed, since it seems to be the same (0x100)
on all models I have seen
- Support for more hotkeys by the "hotkey" sysctl
- Improved support of ACPI events. Disabled by default, since it unexpectedly
changes the behaviour of some keys. (on my T41p there are now 24 different
keypress events that get reported)
- write support for: volume, mute, lcd_brightness and thinklight
- led(4) interface for the thinklight [1]
- New sysctls "fan" and "fan_speed" to support reading of fan status and speed
- New sysctl "thermal" to support reading of up to 8 thermal sensors

- Implement sampling modes and logging support in hwpmc(4).
- Separate MI and MD parts of hwpmc(4) and allow sharing of
PMC implementations across different architectures.
Add support for P4 (EMT64) style PMCs to the amd64 code.
- New pmcstat(8) options: -E (exit time counts) -W (counts
every context switch), -R (print log file).
- pmc(3) API changes, improve our ability to keep ABI compatibility
in the future. Add more 'alias' names for commonly used events.
- bug fixes & documentation.
makes the amount of spare room consistent across architectures, and gets
rid of some cases where space was wasted-and-unusable because types have
different sizes & alignment on different hardware platforms. This change
causes more variables to move around on i386, and is much less disruptive
on other platforms. This has been tested on i386, ppc, and sparc, and has
at least been compiled on everything but arm.

1 show only mount-points below jail's chroot and show only part of the
mount-point's path (if jail's chroot directory is /jails/foo and
mount-point is /jails/foo/usr/home only /usr/home will be shown)

One can check if invisible process is active, by doing:
# ktrace -p <pid>
If ktrace returns 'Operation not permitted' the process is alive and
if returns 'No such process' there is no such process.
