This series aims at porting interrupt entry/exit in C on PPC32, using
the work already merged for PPC64.

First two patches are a fix and an optimisation of unrecoverable_exception() function.

Six following patches do minimal changes in 40x in order to be able to enable MMU
earlier in exception entry.

[...]

Patch 1 applied to powerpc/fixes.
