ccfb965433 Add META_MODE support.
Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.

Still need to add real targets under targets/ to build packages.

Add also a new way to specify the level type to cpucontrol(8) as

4ced504bff cpucontrol: use CPUCTL_UPDATE ioctl on correct file descriptor
I guess that means that microcode update has never worked for AMD CPUs.
Please also note that only older AMD CPUs and micrcode file format are
supported anyway (pre 10h family).

0bb2aabf26 Hide DIR definition by making it an opaque struct typedef.
Introduce dirfd() libc exported symbol replacing macro with same name,
preserve _dirfd() macro for internal use.

Replace dirp->dd_fd with dirfd() call. Avoid using dirfd as variable
name to prevent shadowing global symbol.

I was considering committing all these patches one by one, but as
discussed with brooks@, there is no need to do this. If we ever
need/want to merge these changes back, it is still possible to do this
per application.

b2d758545b - Add support to atomically set/clear individual bits of a MSR register
via cpuctl(4) driver.  Two new CPUCTL_MSRSBIT and CPUCTL_MSRCBIT ioctl(2)
  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).

e085f869d5 - Add cpuctl(4) pseudo-device driver to provide access to some low-level
features of CPUs like reading/writing machine-specific registers,
  retrieving cpuid data, and updating microcode.
- Add cpucontrol(8) utility, that provides userland access to
  the features of cpuctl(4).
- Add subsequent manpages.

The cpuctl(4) device operates as follows. The pseudo-device node cpuctlX
is created for each cpu present in the systems. The pseudo-device minor
number corresponds to the cpu number in the system. The cpuctl(4) pseudo-
device allows a number of ioctl to be preformed, namely RDMSR/WRMSR/CPUID
and UPDATE. The first pair alows the caller to read/write machine-specific
registers from the correspondent CPU. cpuid data could be retrieved using
the CPUID call, and microcode updates are applied via UPDATE.

The permissions are inforced based on the pseudo-device file permissions.
RDMSR/CPUID will be allowed when the caller has read access to the device
node, while WRMSR/UPDATE will be granted only when the node is opened
for writing. There're also a number of priv(9) checks.

The cpucontrol(8) utility is intened to provide userland access to
the cpuctl(4) device features. The utility also allows one to apply
cpu microcode updates.

Currently only Intel and AMD cpus are supported and were tested.
