We don't actually expect that to happen, it's only been seen # on mambo (simulator) in some configurations. # # A zero-size l1d_size leads to the loop in the asm wrapping around to # 2^64-1, and then walking off the end of the fallback area and # eventually causing a page fault which is fatal. # # Just default to 64K which is correct on some CPUs, and sane enough to # not cause a crash on others. # # Fixes: aa8a5e0062ac9 ('powerpc/64s: Add support for RFI flush of L1-D cache') # Signed-off-by: Madhavan Srinivasan <maddy@linux.vnet.ibm.com> # [mpe: Rewrite comment and change log] # 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 9dfbf78e4114fcaf4ef61c49885c3ab5bad40d0b # < make -s -j 40 ARCH=powerpc O=/kisskb/build/powerpc-fixes_83xx_kmeter1_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- 83xx/kmeter1_defconfig # make -s -j 40 ARCH=powerpc O=/kisskb/build/powerpc-fixes_83xx_kmeter1_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/kernel/rcu/srcutree.c: In function 'init_srcu_struct_fields': /kisskb/src/kernel/rcu/srcutree.c:127:33: warning: 'levelspread[<Ub1e0>]' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/rcu/srcutree.c:94:6: note: 'levelspread[<Ub1e0>]' was declared here /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/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:340:21: note: 'pdeo' was declared here /kisskb/src/net/bridge/br_netlink.c: In function 'br_afspec': /kisskb/src/net/bridge/br_netlink.c:635:7: warning: 'err' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c: In function 'univ8250_release_irq': /kisskb/src/drivers/tty/serial/8250/8250_core.c:251:18: warning: 'i' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c:231:19: note: 'i' was declared here /kisskb/src/drivers/net/tun.c: In function 'tun_get_user': /kisskb/src/drivers/net/tun.c:1827:30: warning: 'copylen' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/net/tun.c:1737:46: warning: 'linear' may be used uninitialized in this function [-Wuninitialized] INFO: Uncompressed kernel (size 0x4a8d70) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) Image Name: Linux-4.17.0-rc1-g9dfbf78 Created: Tue Apr 17 21:00:58 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2365072 Bytes = 2309.64 kB = 2.26 MB Load Address: 00000000 Entry Point: 00000000 Completed OK # rm -rf /kisskb/build/powerpc-fixes_83xx_kmeter1_defconfig_powerpc # Build took: 0:00:17.773943
