But at this point, when using VMAP stack the DATA MMU # translation has already been re-enabled, leading to deadlock. # # Don't use the physical address of the stack when # CONFIG_VMAP_STACK is set. # # Signed-off-by: Christophe Leroy # Reported-by: Guenter Roeck # Fixes: 028474876f47 ("powerpc/32: prepare for CONFIG_VMAP_STACK") # Tested-by: Guenter Roeck # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/daeacdc0dec0416d1c587cc9f9e7191ad3068dc0.1581095957.git.christophe.leroy@c-s.fr # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/m68k-linux/bin/m68k-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/m68k-linux/bin/m68k-linux-ld --version # < git log --format=%s --max-count=1 d4bf905307a1c90a27714ff7a9fd29b0a2ceed98 # < make -s -j 48 ARCH=m68k O=/kisskb/build/powerpc-fixes_m68k-defconfig_m68k CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/m68k-linux/bin/m68k-linux- defconfig # make -s -j 48 ARCH=m68k O=/kisskb/build/powerpc-fixes_m68k-defconfig_m68k CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/m68k-linux/bin/m68k-linux- In file included from /kisskb/src/arch/m68k/include/asm/amigayle.h:21, from /kisskb/src/arch/m68k/include/asm/io_mm.h:59, from /kisskb/src/arch/m68k/include/asm/io.h:8, from /kisskb/src/include/linux/clocksource.h:21, from /kisskb/src/arch/m68k/amiga/config.c:20: /kisskb/src/arch/m68k/amiga/config.c: In function 'amiga_identify': /kisskb/src/arch/m68k/include/asm/amigahw.h:42:50: warning: this statement may fall through [-Wimplicit-fallthrough=] #define AMIGAHW_SET(name) (amiga_hw_present.name = 1) ~~~~~~~~~~~~~~~~~~~~~~~^~~~ /kisskb/src/arch/m68k/amiga/config.c:223:3: note: in expansion of macro 'AMIGAHW_SET' AMIGAHW_SET(PCMCIA); ^~~~~~~~~~~ /kisskb/src/arch/m68k/amiga/config.c:224:2: note: here case AMI_500: ^~~~ /kisskb/src/arch/m68k/mvme16x/config.c: In function 'mvme16x_hwclk': /kisskb/src/arch/m68k/mvme16x/config.c:440:2: warning: #warning check me!
