But it's not # needed for assembly files. # # The minimal fix is to move the addition to BOOT_CFLAGS of -include # compiler_attributes.h until after we've copied BOOT_CFLAGS into # BOOT_AFLAGS. That avoids including compiler_attributes.h for asm files, # but makes no other change to BOOT_CFLAGS or BOOT_AFLAGS. # # Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> # Debugged-by: Linus Torvalds <torvalds@linux-foundation.org> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Tested-by: Guenter Roeck <linux@roeck-us.net> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-gcc --version # < /opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-ld --version # < git log --format=%s --max-count=1 1619b69edce14c4a4665fa8ff4c587dcc77202a9 # < make -s -j 32 ARCH=sparc64 O=/kisskb/build/linus_sparc64-allmodconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_HAVE_FTRACE_MCOUNT_RECORD=n # Added to kconfig CONFIG_SAMPLES=n # Added to kconfig CONFIG_MODULE_SIG=n # < make -s -j 32 ARCH=sparc64 O=/kisskb/build/linus_sparc64-allmodconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- help # make -s -j 32 ARCH=sparc64 O=/kisskb/build/linus_sparc64-allmodconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- olddefconfig # make -s -j 32 ARCH=sparc64 O=/kisskb/build/linus_sparc64-allmodconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- <stdin>:1515:2: warning: #warning syscall clone3 not implemented [-Wcpp] In file included from /kisskb/src/include/linux/kernel.h:16:0, from /kisskb/src/include/linux/list.h:9, from /kisskb/src/include/linux/module.h:12, from /kisskb/src/drivers/gpu/drm/ttm/ttm_pool.c:34: /kisskb/src/drivers/gpu/drm/ttm/ttm_pool.c: In function 'ttm_pool_alloc': /kisskb/src/include/linux/minmax.h:20:28: error: comparison of distinct pointer types lacks a cast [-Werror] (!!(sizeof((typeof(x) )1 == (typeof(y) )1))) ^ /kisskb/src/include/linux/minmax.h:26:4: note: in expansion of macro '__typecheck' (__typecheck(x, y) && __no_side_effects(x, y)) ^ /kisskb/src/include/linux/minmax.h:36:24: note: in expansion of macro '__safe_cmp' __builtin_choose_expr(__safe_cmp(x, y), \ ^ /kisskb/src/include/linux/minmax.h:45:19: note: in expansion of macro '__careful_cmp' #define min(x, y) __careful_cmp(x, y, <) ^ /kisskb/src/drivers/gpu/drm/ttm/ttm_pool.c:386:15: note: in expansion of macro 'min' for (order = min(MAX_ORDER - 1UL, __fls(num_pages)); num_pages; ^ cc1: all warnings being treated as errors make[5]: * [/kisskb/src/scripts/Makefile.build:277: drivers/gpu/drm/ttm/ttm_pool.o] Error 1 make[5]: * Waiting for unfinished jobs.... make[4]: * [/kisskb/src/scripts/Makefile.build:540: drivers/gpu/drm/ttm] Error 2 make[4]: * Waiting for unfinished jobs.... make[3]: * [/kisskb/src/scripts/Makefile.build:540: drivers/gpu/drm] Error 2 make[2]: * [/kisskb/src/scripts/Makefile.build:540: drivers/gpu] Error 2 make[2]: * Waiting for unfinished jobs.... make[1]: * [/kisskb/src/Makefile:1868: drivers] Error 2 make: *** [Makefile:219: __sub-make] Error 2 Command 'make -s -j 32 ARCH=sparc64 O=/kisskb/build/linus_sparc64-allmodconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/linus_sparc64-allmodconfig_sparc64 # Build took: 0:06:02.808781
