Subject: compat: extend phys_addr_t backport to 2.6.24
X-Git-Tag: compat-2012-07-02~23
X-Git-Url: https://git.openfabrics.org/?p=~emulex%2Ffor-vlad%2Fold%2Fcompat.git;a=commitdiff_plain;h=b861c7e684d90598f8662f7cbb9ca7f7df0d5efc;ds=sidebyside

compat: extend phys_addr_t backport to 2.6.24

x86 only got phys_addr_t as of 2.6.25. This patch addresses
that. The only arch that had phys_addr_t prior to that is
PPC.
