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/x86_64-linux/bin/x86_64-linux-gcc --version # < git log --format=%s --max-count=1 9dfbf78e4114fcaf4ef61c49885c3ab5bad40d0b # < make -s -j 40 ARCH=x86_64 O=/kisskb/build/powerpc-fixes_x86_64-allnoconfig_x86_64 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/x86_64-linux/bin/x86_64-linux- allnoconfig # make -s -j 40 ARCH=x86_64 O=/kisskb/build/powerpc-fixes_x86_64-allnoconfig_x86_64 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/x86_64-linux/bin/x86_64-linux- /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/arch/x86/kernel/apic/io_apic.c: In function 'mp_map_pin_to_irq': /kisskb/src/arch/x86/kernel/apic/io_apic.c:1033:6: warning: 'irq' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/arch/x86/kernel/e820.c: In function 'e820__setup_pci_gap': /kisskb/src/arch/x86/kernel/e820.c:650:16: warning: 'gapstart' may be used uninitialized in this function [-Wuninitialized] Completed OK # rm -rf /kisskb/build/powerpc-fixes_x86_64-allnoconfig_x86_64 # Build took: 0:00:27.155998
