If the virtual mode handler is # reached, it will lock and restore the AMR. # # Fixes: 890274c2dc4c0 ("powerpc/64s: Implement KUAP for Radix MMU") # Cc: Russell Currey <ruscur@russell.cc> # Signed-off-by: Nicholas Piggin <npiggin@gmail.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-gcc --version # < /opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-ld --version # < git log --format=%s --max-count=1 e13e7cd4c0c1cc9984d9b6a8663e10d76b53f2aa # < make -s -j 48 ARCH=sparc64 O=/kisskb/build/powerpc-fixes_sparc64-defconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- defconfig # make -s -j 48 ARCH=sparc64 O=/kisskb/build/powerpc-fixes_sparc64-defconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- /kisskb/src/net/ipv4/fib_semantics.c: In function 'fib_check_nh_v4_gw': /kisskb/src/net/ipv4/fib_semantics.c:1027:12: warning: 'err' may be used uninitialized in this function [-Wmaybe-uninitialized] if (!tbl \|\| err) { ^ WARNING: EXPORT symbol "_mcount" [vmlinux] version generation failed, symbol will not be versioned.
