guess wrong for buildkernel when CC=gcc49, say. Eliminate all the
guessing. COMPILER_TYPE propigates properly on its own, if specified,
and we guess it correctly otherwise lower in the build. Also, fix
conditionals for armv6hf when using an external compiler chain. They
were broken before, but unused. Also, prefer checking the compiler
type over CLANG_IS_CC since the latter is only supposed to be used to
determine what symlinks to install (more fixes to follow).
when both WITH_FOO and WITHOUT_FOO are set. Use this where
possible. Only disallow setting of MK_FOO on the command line. This
was preferable to inventing a new mechanism or fixing the undef bug
(bin/183762) which precludes users from turning off anything we turn
off for parts of the build with WITHOUT_FOO prior to this.

Support covers device drivers for:
- Interrupt Combiner
- gpio/pad, External Interrupts Controller (pad)
- I2C Interface
- Chrome Embedded Controller
- Chrome Keyboard
Also:
- Use new gpio dev class in EHCI driver
- Expand device tree information
* Save the required VFP registers on context switch. If the exception bit
is set we need to save and restore the FPINST register, and if the fp2v
bit is also set we need to save and restore FPINST2.
* Move saving and restoring the floating point control registers to C.
* Clear the fpexc exception and fp2v flags on a floating-point exception.
* Signal a SIGFPE if the fpexc exception flag is set on an undefined
instruction. This is how the ARM core signals to software there is a
floating-point exception.
is already correctly reset to the FPU user save area, only PCB_KERNFPU
flag might leak from old thread state into the new state.
For creation of the user-mode thread, the change is nop since
corresponding syscall code does not use FPU. On the other hand,
creation of a kernel thread forks from a thread selected arbitrary
from proc0, which might use FPU.

o Move vd_bitbltchr vga's driver method to vd_maskbitbltchr.
o Implement new vd_bitbltchr method for vga driver. (It do single write for 8
pixels, have to be a bit faster).

- When clearing a bit for a cpuid in pmap->pm_save, ensure that the
cpuid is not set in pm_active. The pm_save indicates which CPUs may
have cached translations for given PCID, which implies that a CPU
executing with the given pmap active have the translations
cached. [1]
- In smp_masked_invltlb(), pass pmap to smp_targeted_tlb_shootdown(). [1]
- In invlrng_handler(), check for the special values of pcid (0 and
-1) and do corresponding global or total invalidations before
checking for performing PCID-specific range invalidation with
INVPCID_ADDR. [2]
- In invltlb_pcid_handler(), do not read %cr3 unless needed. [2]
- Do minor style tweaks. [2]
