Subject: bootmem: fix wrong call parameter for free_bootmem()
X-Git-Tag: next-20121205~1^2~284
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=83d43e1a5103ff222c5ad5fdaf0a6bab7c4cb37e;p=karo-tx-linux.git

bootmem: fix wrong call parameter for free_bootmem()

It is strange that alloc_bootmem() returns a virtual address and
free_bootmem() requires a physical address.  Anyway, free_bootmem()'s
first parameter should be physical address.

There are some call sites for free_bootmem() with virtual address.  So fix
them.
