This causes all new # architecture features to be made available when running on newer # processors with new architecture features added to the PCR as bits # must be set to disable a given feature. # # For example to disable new features added as part of Version 2.07 of # the ISA the corresponding bit in the PCR needs to be set. # # As new processor features generally require explicit kernel support # they should be disabled until such support is implemented. Therefore # kernels should set all unknown/reserved bits in the PCR such that any # new architecture features which the kernel does not currently know # about get disabled. # # An update is planned to the ISA to clarify that the PCR is an # exception to the Programming Note on reserved bits in Section 1.3.3. # # Signed-off-by: Jordan Niethe # [alistair: Added some clarifications to the commit message] # Signed-off-by: Alistair Popple # Tested-by: Joel Stanley # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/20190910060102.21597-1-alistair@popple.id.au # < /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 516627be26024f9952005a3116cbdb9d6dc24428 # < make -s -j 80 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 80 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);
