Re: [PATCH] arm: 9016/2: Make symbol 'tmp_pmd_table' static

[Liu Shixin]

I'm sorry for making such a stupid mistake. There was only one patch committed before(5615f69bc209 "ARM: 9016/2: Initialize the mapping of KASan shadow memory"), and I used the same subject by mistake.

Thanks for your correction, I will revise the subject and resend it. How about using "arm: mm: kasan_init" in the subject?
