[PATCH v3 00/42] powerpc/64: use asm sections for head/exception layout

[Michael Ellerman]

This is v3 of Nick's series to change the way we construct the 64-bit Book3S
exception vectors, as applied to the tree by me.

Changes since his v2 are:
 - macro names have been shortened to EXC_REAL() etc.
 - the end macros which were empty have been dropped (until/if we need them)
 - some minor fixes for older toolchains.

Any bugs introduced since v2 are mine :)

cheers
