New Revision: 272209
URL: http://svnweb.freebsd.org/changeset/base/272209
Log:
Add machine/sysreg.h to simplify accessing the system control coprocessor
registers and use it in the ARMv7 CPU functions.
The sysreg.h file has been checked by hand, however it may contain errors
with the comments on when a register was first introduced. The ARMv7 cpu
functions have been checked by compiling both the previous and this version
and comparing the md5 of the object files.

Added:
head/sys/arm/include/sysreg.h (contents, props changed)
This one breaks kernel build with gcc-4.2.1.
__ARM_ARCH not defined. On gcc-4.2.1 there is no __ARM_ARCH builtin.
Later gcc do have it.
The include below fixes the build.
