Hi Lv, Rafael,
Could you help merge this patch for 4.2? It should be in the ACPICA
release of 20150515, but we missed that chance. This patch will be needed
for ARM64 GIC init and I prepare to upstream those patches in 4.3, so if
this patch accpeted in 4.2, it will have less dedenpence for ACPICA core
and ARM64 GIC code in next kernel version.
This patch was accepted by Bob and merged into ACPICA tree, I reworked
it on top of linux ACPICA.
Thanks
Hanjun
