Subject: x86/power/64: Use __pa() for physical address computation
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=5d87f493ddb1b86a0569fa3c4037fa9efc0c7183;p=deliverable%2Flinux.git

x86/power/64: Use __pa() for physical address computation

The value of temp_level4_pgt is the physical address of the
top-level page directory, so use __pa() to compute it.
