[v3][PATCH 0/8] powerpc/book3e: support kexec and kdump

[Tiejun Chen]

This patchset is used to support kexec and kdump on book3e.

Tested on fsl-p5040 DS.

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
