[Gnewsense-dev] Re: [loongson-support 00/27] linux PATCHes of loongson-based machines

[Wu Zhangjin]

hi, all

sorry for sending the EMPTY patches(use the wrong option of format-patch
and without a content check) to you, forgive me :-)

please ignore the E-mails, and i will add a -v1 in the subject to
sending the normal one.

sorry again!!!

best regards,
Wu Zhangjin
