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 <christophe.leroy@c-s.fr> # Reported-by: Guenter Roeck <linux@roeck-us.net> # Fixes: 028474876f47 ("powerpc/32: prepare for CONFIG_VMAP_STACK") # Tested-by: Guenter Roeck <linux@roeck-us.net> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/daeacdc0dec0416d1c587cc9f9e7191ad3068dc0.1581095957.git.christophe.leroy@c-s.fr # < /opt/cross/kisskb/br-microblaze-full-2016.08-613-ge98b4dd/bin/microblazeel-linux-gcc --version # < /opt/cross/kisskb/br-microblaze-full-2016.08-613-ge98b4dd/bin/microblazeel-linux-ld --version # < git log --format=%s --max-count=1 d4bf905307a1c90a27714ff7a9fd29b0a2ceed98 # < make -s -j 48 ARCH=microblaze O=/kisskb/build/powerpc-fixes_mmu_defconfig_microblaze CROSS_COMPILE=/opt/cross/kisskb/br-microblaze-full-2016.08-613-ge98b4dd/bin/microblazeel-linux- mmu_defconfig # make -s -j 48 ARCH=microblaze O=/kisskb/build/powerpc-fixes_mmu_defconfig_microblaze CROSS_COMPILE=/opt/cross/kisskb/br-microblaze-full-2016.08-613-ge98b4dd/bin/microblazeel-linux- /kisskb/src/kernel/debug/kdb/kdb_main.c: In function 'kdb_rd': /kisskb/src/kernel/debug/kdb/kdb_main.c:1857:11: error: 'dbg_reg_def' undeclared (first use in this function) rsize = dbg_reg_def[i].size * 2; ^ /kisskb/src/kernel/debug/kdb/kdb_main.c:1857:11: note: each undeclared identifier is reported only once for each function it appears in /kisskb/src/kernel/debug/kdb/kdb_main.c:1868:12: error: implicit declaration of function 'dbg_get_reg' [-Werror=implicit-function-declaration] rname = dbg_get_reg(i, &reg8, kdb_current_regs); ^ /kisskb/src/kernel/debug/kdb/kdb_main.c:1868:10: warning: assignment makes pointer from integer without a cast [-Wint-conversion] rname = dbg_get_reg(i, &reg8, kdb_current_regs); ^ /kisskb/src/kernel/debug/kdb/kdb_main.c:1874:10: warning: assignment makes pointer from integer without a cast [-Wint-conversion] rname = dbg_get_reg(i, &reg16, kdb_current_regs); ^ /kisskb/src/kernel/debug/kdb/kdb_main.c:1880:10: warning: assignment makes pointer from integer without a cast [-Wint-conversion] rname = dbg_get_reg(i, &reg32, kdb_current_regs); ^ /kisskb/src/kernel/debug/kdb/kdb_main.c:1886:10: warning: assignment makes pointer from integer without a cast [-Wint-conversion] rname = dbg_get_reg(i, &reg64, kdb_current_regs); ^ cc1: some warnings being treated as errors make[4]: * [/kisskb/src/scripts/Makefile.build:265: kernel/debug/kdb/kdb_main.o] Error 1 make[4]: * Waiting for unfinished jobs.... make[3]: * [/kisskb/src/scripts/Makefile.build:503: kernel/debug/kdb] Error 2 make[2]: * [/kisskb/src/scripts/Makefile.build:503: kernel/debug] Error 2 make[2]: * Waiting for unfinished jobs.... make[1]: * [/kisskb/src/Makefile:1681: kernel] Error 2 make[1]: * Waiting for unfinished jobs.... make: * [Makefile:179: sub-make] Error 2 Command 'make -s -j 48 ARCH=microblaze O=/kisskb/build/powerpc-fixes_mmu_defconfig_microblaze CROSS_COMPILE=/opt/cross/kisskb/br-microblaze-full-2016.08-613-ge98b4dd/bin/microblazeel-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/powerpc-fixes_mmu_defconfig_microblaze # Build took: 0:00:40.450456
