15785fbe81 Add support for _PDC/_OSC by advertising that we support direct access to
the PERF_CTL/STS MSRs via the new acpi_get_features() method.  This should
allow newer systems to use SpeedStep.

b29224c2a0 Add the acpi_get_features() method. This method is called on child drivers
to see what features they may support before calling identify/probe/attach.
This is necessary because the ACPI 3.0 spec requires driver support be
advertised before running any methods.  For now, the flags are as specified
in for the _PDC and _OSC methods but we can support private flags as needed.

Add an implementation of this for acpi_cpu.  It checks all its children
(notably cpufreq drivers) and calls the _PDC method to report the results.

fada20b989 Add devclass_get_drivers(9) which provides an array of pointers to driver
instances in a given devclass.  This is useful for systems that want to
call code in driver static methods, similar to device_identify().

92b8231d4f - Instead of waiting forever to get a vnode in getnewvnode() wait for
one to become available for one second and then return ENFILE.  We
   can run out of vnodes, and there must be a hard limit because without
   one we can quickly run out of KVA on x86.  Presently the system can
   deadlock if there are maxvnodes directories in the namecache.  The
   original 4.x BSD behavior was to return ENFILE if we reached the max,
   but 4.x BSD did not have the vnlru proc so it was less profitable to
   wait.

a44732323f maxunit is actually one higher than the greatest currently-allocated unit
in a devclass.  All the other uses of maxunit are correct and this one was
safe since it checks the return value of devclass_get_device(), which would
always say that the highest unit device doesn't exist.

bcc8f66c8b - Use M_ZERO rather than explicitly calling bzero().
- Don't intermingle direct calls to lockmgr and indirect calls through
   VOPs.  This will be important in the future.
 - Dont lock the devvp's interlock just to release it on the next line by
   passing LK_INTERLOCK to lockmgr.

   devvp's interlock locked.

41d4783d49 - In ffs_sync we need to pass LK_SLEEPFAIL in when we lock the vnode

153910e0f5 - Move the contents of softdep_disk_prewrite into ffs_geom_strategy to fix
two bugs.
 - ffs_disk_prewrite was pulling the vp from the buf and checking for
   COPYONWRITE, when really it wanted the vp from the bufobj that we're
   writing to, which is the devvp.  This lead to us skipping the copy on
   write to all file data, which significantly broke snapshots for the
   last few months.
 - When the SOFTUPDATES option was not included in the kernel config we
   would also skip the copy on write check, which would effectively disable
   snapshots.
 - Remove an invalid mp_fixme().

f0ddc75ed0 - Now that writes to character devices supporting softupdates can
generate dirty bufs even with a locked vnode, 100 retries is not that
   many.  This should probably change from a retry count to an abort when
   we are no longer cleaning any buffers.
 - Don't call vprint() while we still hold the vnode locked.  Move the call
   to later in the function.
 - Clean up a comment.

f0ceb98f93 Replace the current strspn() and strcspn() with significantly faster
implementations inspired by the ones in DragonFly.  Unlike the
DragonFly versions, these have a small data cache footprint, and my
tests show that they're never slower than the old code except when the
charset or the span is 0 or 1 characters.  This implementation is
generally faster than DragonFly until either the charset or the span
gets in the ballpark of 32 to 64 characters.

3df129097b The file machine/ieeefp.h needs sys/cdefs.h on amd64 and i386 after my
compiler features tests. This is ok, since machine/ieeefp.h is an internal
interface. But floatingpoint.h is a public interface and some ports use it,
so include sys/cdefs.h in the amd64 and i386 version of floatingpoint.h.

Note: some architectures don't provide recursive inclusion protection in
floatingpoint.h, namely alpha and ia64. Except for this part and now the
include of sys/cdefs.h, all those files are equal (from a compiler POV),
so they could be moved to only one version in src/include/.

5e9b87a863 Add some missing errnos from POSIX. Nothing in FreeBSD generates
these at the moment, but applications that test for them will now
have a better chance of compiling.

I have intentionally omitted errnos that are only good for STREAMS,
since apps that use STREAMS won't compile anyway.  The exception is
EPROTO, which was apparently intended for STREAMS, but worth having
anyway because Linux (mis)uses it for other things.

98df9218da - Change the vm_mmap() function to accept an objtype_t parameter specifying
the type of object represented by the handle argument.
- Allow vm_mmap() to map device memory via cdev objects in addition to
  vnodes and anonymous memory.  Note that mmaping a cdev directly does not
  currently perform any MAC checks like mapping a vnode does.
- Unbreak the DRM getbufs ioctl by having it call vm_mmap() directly on the
  cdev the ioctl is acting on rather than trying to find a suitable vnode
  to map from.
