This some janitorial work on head.S, just stuff I noticed when making
changes to it for other reasons.
This still needs acks on patches #2, #5 and #8
Changes since v4:
- included Marc Zyngier's struct cpu_table removal patch
- dropped __lookup_processor_type_data patch now that Marc has nuked the
whole thing
- added patch to merge __enable_mmu() and __turn_mmu_on() into a single
function, as there is no need for funky trampoline stuff when you have
two non-overlapping TTBRs
- added patch to remove __calc_phys_offset and use PC-relative references or
absolute (linker generated) references as appropriate
- added patch to complain when x1/x2/x3 are non-zero, which helps ensure that
we will ever be able to use them for anything
- added R-b's
Changes since v3:
- added similar patch for secondary_holding_pen_release
- fixed bug in patch #1 (ldr_l)
Changes since v2:
- added separate patch to add macros for adrp/add, adrp/ldr and adrp/str
- added R-b's
