That # means the lack of AT_BASE_PLATFORM is a user-visible artifact of the # fact that the kernel is using DT CPU features, which we don't want. # # So set it in the DT CPU features code also. # # This results in eg: # $ LD_SHOW_AUXV=1 /bin/true \| grep "AT_.PLATFORM" # AT_PLATFORM: power9 # AT_BASE_PLATFORM:power9 # # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Reviewed-by: Nicholas Piggin <npiggin@gmail.com> # < /opt/cross/kisskb/gcc-4.6.3-nolibc/sh4-linux/bin/sh4-linux-gcc --version # < git log --format=%s --max-count=1 e4b79900222b8cccd4da4a7a89581f0e1b764ed2 # < make -s -j 48 ARCH=sh O=/kisskb/build/powerpc-fixes_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-fixes_sh-defconfig_sh4 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/sh4-linux/bin/sh4-linux- Generating include/generated/machtypes.h <stdin>:1317:2: warning: #warning syscall pkey_mprotect not implemented [-Wcpp] <stdin>:1320:2: warning: #warning syscall pkey_alloc not implemented [-Wcpp] <stdin>:1323:2: warning: #warning syscall pkey_free not implemented [-Wcpp] <stdin>:1326:2: warning: #warning syscall statx 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:389: Warning: overflow in branch to syscall_exit_work; converted into longer instruction sequence /kisskb/src/arch/sh/kernel/cpu/sh4/../sh3/../../entry-common.S:392: Warning: overflow in branch to syscall_exit_work; converted into longer instruction sequence /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:183:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/rcu/srcutree.c: In function 'init_srcu_struct_fields': /kisskb/src/kernel/rcu/srcutree.c:146:32: warning: 'levelspread[<U1140>]' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/rcu/srcutree.c:94:6: note: 'levelspread[<U1140>]' was declared here /kisskb/src/kernel/cgroup/cgroup-v1.c: In function 'cgroup1_mount': /kisskb/src/kernel/cgroup/cgroup-v1.c:1268:20: warning: 'root' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/mpage.c: In function 'do_mpage_readpage': /kisskb/src/fs/mpage.c:316:1: warning: the frame size of 1088 bytes is larger than 1024 bytes [-Wframe-larger-than=] /kisskb/src/fs/mpage.c: In function '__mpage_writepage': /kisskb/src/fs/mpage.c:676:1: warning: the frame size of 1152 bytes is larger than 1024 bytes [-Wframe-larger-than=] /kisskb/src/mm/vmstat.c: In function 'sysctl_vm_numa_stat_handler': /kisskb/src/mm/vmstat.c:89:5: warning: 'oldval' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/mm/hugetlb.c: In function 'alloc_pool_huge_page': /kisskb/src/mm/hugetlb.c:1439:5: warning: 'page' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/sh/clk/cpg.c: In function 'r8': /kisskb/src/drivers/sh/clk/cpg.c:41:2: warning: passing argument 1 of 'ioread8' discards 'const' qualifier from pointer target type [enabled by default] /kisskb/src/include/asm-generic/iomap.h:29:21: note: expected 'void ' but argument is of type 'const void ' /kisskb/src/drivers/sh/clk/cpg.c: In function 'r16': /kisskb/src/drivers/sh/clk/cpg.c:46:2: warning: passing argument 1 of 'ioread16' discards 'const' qualifier from pointer target type [enabled by default] /kisskb/src/include/asm-generic/iomap.h:30:21: note: expected 'void ' but argument is of type 'const void ' /kisskb/src/drivers/sh/clk/cpg.c: In function 'r32': /kisskb/src/drivers/sh/clk/cpg.c:51:2: warning: passing argument 1 of 'ioread32' discards 'const' qualifier from pointer target type [enabled by default] /kisskb/src/include/asm-generic/iomap.h:32:21: note: expected 'void ' but argument is of type 'const void *' /kisskb/src/fs/ext4/readpage.c: In function 'ext4_mpage_readpages': /kisskb/src/fs/ext4/readpage.c:294:1: warning: the frame size of 1200 bytes is larger than 1024 bytes [-Wframe-larger-than=] Kernel: arch/sh/boot/zImage is ready Completed OK # rm -rf /kisskb/build/powerpc-fixes_sh-defconfig_sh4 # Build took: 0:00:40.418964
