If that happens, the linux code # confusingly treats 0xffffffff as a valid IRQ number and panics at some # point. # # A fix was recently merged in skiboot: # # e97391ae2bb5 ("xive: fix return value of opal_xive_allocate_irq()") # # but we need a workaround anyway to support older skiboots already # in the field. # # Internally convert 0xffffffff to OPAL_RESOURCE which is the usual error # returned upon resource exhaustion. # # Cc: stable@vger.kernel.org # v4.12+ # Signed-off-by: Greg Kurz <groug@kaod.org> # Reviewed-by: Cédric Le Goater <clg@kaod.org> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/156821713818.1985334.14123187368108582810.stgit@bahia.lan # < /opt/cross/kisskb/gcc-4.6.3-nolibc/sh4-linux/bin/sh4-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/sh4-linux/bin/sh4-linux-ld --version # < git log --format=%s --max-count=1 6ccb4ac2bf8a35c694ead92f8ac5530a16e8f2c8 # < make -s -j 48 ARCH=sh O=/kisskb/build/powerpc-next_sh-defconfig_sh4 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/sh4-linux/bin/sh4-linux- defconfig # make -s -j 48 ARCH=sh O=/kisskb/build/powerpc-next_sh-defconfig_sh4 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/sh4-linux/bin/sh4-linux- Generating include/generated/machtypes.h <stdin>:1511:2: warning: #warning syscall clone3 not implemented [-Wcpp] /kisskb/src/arch/sh/kernel/cpu/sh4/../sh3/../../entry-common.S: Assembler messages: /kisskb/src/arch/sh/kernel/cpu/sh4/../sh3/../../entry-common.S:385: Warning: overflow in branch to syscall_exit_work;
