[PATCH] PowerPC: kernel: compiling issue, make additional room inexception vector area

From: Chen Gang
Date: Thu Apr 25 2013 - 04:19:34 EST



When CONFIG_KVM_BOOK3S_64_PR is enabled,
MASKABLE_EXCEPTION_PSERIES(0x900 ...) will includes __KVMTEST, it will
exceed 0x980 which STD_EXCEPTION_HV(0x980 ...) will use, it will cause
compiling issue.

The related errors:
arch/powerpc/kernel/exceptions-64s.S: Assembler messages:
arch/powerpc/kernel/exceptions-64s.S:258: Error: attempt to move .org backwards
make[1]: *** [arch/powerpc/kernel/head_64.o] Error 1
