Subject: [PATCH] powerpc/64s: Fix MASKABLE_RELON_EXCEPTION_HV_OOL macro
Date: Tue, 6 Feb 2018 18:06:37 +0530 [thread overview]
Message-ID: <1517920597-14588-1-git-send-email-maddy@linux.vnet.ibm.com> (raw)
Commit f14e953b191f ("powerpc/64s: Add support to take additional parameter in MASKABLE_* macro")
messed up MASKABLE_RELON_EXCEPTION_HV_OOL macro by adding the wrong
__SOFTEN__ test which caused guest kernel trash at boot. Patch to fix
the macro to use SOFTEN_TEST_HV instead of SOFTEN_NOTEST_HV.
