* Fix kexec build failure with CONFIG_THUMB2_KERNEL.
* Avoids deprecated/forbidden sp and pc usage in for ARMv7
onwards, retaining compatibility with older architecture
versions.
* The pc value saved to newregs is now aligned on a predictable
instruction boundary.
(stmia { ... pc } or str pc has implementation-defined results
in most versions of the ARM architecutre, and is prohibited
(unpredictable) in Thumb-2.)
* Switch to named inline asm arguments (else I get readily
confused ...)
The resulting code should be compatible with all architecture
versions >= v3, with or without CONFIG_THUMB2_KERNEL.
