Subject: kvm: ppc: Add SPRN_EPR get helper function
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=34f754b99e2f642c661967b456764b2c7ccc096e;p=linux-beck.git

kvm: ppc: Add SPRN_EPR get helper function

kvmppc_set_epr() is already defined in asm/kvm_ppc.h, So
rename and move get_epr helper function to same file.
