f7a6947cd49b7ff4e03f1b4f7e7b223003d752ca # Author: Michael Ellerman <mpe@ellerman.id.au> # Date: Tue Jul 10 16:20:56 2018 +1000 # # powerpc/uaccess: Enable get_user(u64, *p) on 32-bit # # Currently if you build a 32-bit powerpc kernel and use get_user() to # load a u64 value it will fail to build with eg: # # kernel/rseq.o: In function `rseq_get_rseq_cs': # kernel/rseq.c:123: undefined reference to `__get_user_bad' # # This is hitting the check in __get_user_size() that makes sure the # size we're copying doesn't exceed the size of the destination: # # #define __get_user_size(x, ptr, size, retval) # do { # retval = 0; # __chk_user_ptr(ptr); # if (size > sizeof(x)) # (x) = __get_user_bad(); # # Which doesn't immediately make sense because the size of the # destination is u64, but it's not really, because __get_user_check() # etc. internally create an unsigned long and copy into that: # # #define __get_user_check(x, ptr, size) # ({ # long __gu_err = -EFAULT; # unsigned long __gu_val = 0; # # The problem being that on 32-bit unsigned long is not big enough to # hold a u64. We can fix this with a trick from hpa in the x86 code, we # statically check the type of x and set the type of __gu_val to either # unsigned long or unsigned long long. # # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < git log --format=%s --max-count=1 f7a6947cd49b7ff4e03f1b4f7e7b223003d752ca # < make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_powerpc-randconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- randconfig KCONFIG_SEED=0x51A325BC # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_CPU_BIG_ENDIAN=y # Added to kconfig CONFIG_PPC64=y # Added to kconfig CONFIG_PPC_DISABLE_WERROR=y # Added to kconfig CONFIG_SECTION_MISMATCH_WARN_ONLY=y # Added to kconfig CONFIG_PREVENT_FIRMWARE_BUILD=y # Added to kconfig CONFIG_CC_STACKPROTECTOR_STRONG=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig CONFIG_LD_HEAD_STUB_CATCH=y # make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_powerpc-randconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- olddefconfig # make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_powerpc-randconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/arch/powerpc/kernel/eeh.c:1752:12: warning: 'proc_eeh_show' defined but not used [-Wunused-function] /kisskb/src/arch/powerpc/sysdev/xive/common.c: In function 'xive_scan_interrupts': /kisskb/src/arch/powerpc/sysdev/xive/common.c:181:2: warning: 'prio' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/arch/powerpc/sysdev/xive/spapr.c: In function 'xive_spapr_init': /kisskb/src/arch/powerpc/sysdev/xive/spapr.c:727:2: warning: 'max_prio' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/net/Makefile:24: CC cannot link executables.
