Subject: [PATCH] PowerPC: kernel: compiling issue, make additional room in exception vector area
Date: Thu, 25 Apr 2013 16:18:11 +0800 [thread overview]
Message-ID: <5178E6C3.4060603@asianux.com> (raw)
In-Reply-To: <5178ABA2.4030109@linux.vnet.ibm.com>
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
