This patch series makes some enhancement to ITS configuration in the
following three aspects:
o allocation of the ITS tables
o replacing magic numbers with sensible macros
o supporting ITS power down
This patch series is based on linux 3.19-rc6, and tested on Hisilion
ARM64 board with GICv3 ITS
The field of page size in register GITS_BASERn might be read-only
if an implementation only supports a single, fixed page size. But
currently the ITS driver will throw out an error when PAGE_SIZE
is less than the minimum size supported by an ITS. So addressing
this problem by using 64KB pages as
Some kind of brain-dead implementations chooses to insert ITEes in
rapid sequence of disabled ITEes, and an un-zeroed ITT will confuse
ITS on judging whether an ITE is really enabled or not. Considering

in which ITT is not required

Configurations of an ITS cannot be changed if the ITS is in an

with all the active ITSes un-disabled, etc. kexec.
This patch will make sure all the active ITSes disabled before
