Ben,
I don't see any further comments, so could you merge this kindly?
This patchset is used to support kexec and kdump on book3e.
Tested on fsl-p5040 DS.
v4:
* rebase on next branch
v3:
* add one patch to rename interrupt_end_book3e with __end_interrupts then we can have a unique lable for book3e and book3s. * add some comments for "book3e/kexec/kdump: enable kexec for kernel" * clean "book3e/kexec/kdump: introduce a kexec kernel flag"
v2: * rebase on merge branch
v1: * improve some patch head * rebase on next branch with patch 7
