SLOF (guest firmware # used by QEMU) currently doesn't do this so the zImage is not aware of # the initrd location. This can result in initrd corruption either # though the zImage extracting the vmlinux over the initrd, or by the # vmlinux overwriting the initrd when relocating itself. # # QEMU does put the linux,initrd-start and linux,initrd-end properties # into the devicetree to vmlinux to find the initrd. So we can work # around the problem by also looking for those properties in the zImage. # # Cc: stable@vger.kernel.org # Signed-off-by: Oliver O'Halloran # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/20191023013635.2512-1-oohall@gmail.com # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 91288fcc5a7ebb6378f442916299dc20d037aa72 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc6xx_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ppc6xx_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc6xx_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- In file included from /kisskb/src/sound/ppc/pmac.h:12:0, from /kisskb/src/sound/ppc/awacs.c:16: /kisskb/src/sound/ppc/awacs.c: In function 'snd_pmac_awacs_init': /kisskb/src/include/sound/control.h:208:9: warning: 'speaker_vol' may be used uninitialized in this function [-Wmaybe-uninitialized] return _snd_ctl_add_slave(master, slave, 0);
