Re: [PATCH 00/19] Introduce ACPI for ARM64 based on ACPI 5.1

[Hanjun Guo <hanjun.guo@linaro.org>]

Hi folks,

I included the linaro-acpi-private mail list wrongly when I was sending them
out, it will cause Delivery Status Notification (Failure) when you are not
in that mail list, sorry for the messed up, it was a little bit late for me
last night, and little bit dottiness for me too, I must be tired :(

please remove the linaro-acpi-private mail list when you replied, Thanks.

Best Regards
Hanjun
