The tlbie can # race with an mtpid (move to PID register, essentially MMU context # switch) on another thread of the core, which can cause stores to # continue to go to a page after it's unmapped. # # - A fix in our KVM code to add a missing barrier, the lack of which # has been observed to cause missed IPIs and subsequently stuck CPUs # in the host. # # - A change to the way we initialise PCR (Processor Compatibility # Register) to make it forward compatible with future CPUs. # # - On some older PowerVM systems our H_BLOCK_REMOVE support could # oops, fix it to detect such systems and fallback to the old # invalidation method. # # - A fix for an oops seen on some machines when using KASAN on 32-bit. # # - A handful of other minor fixes, and two new selftests. # # Thanks to: Alistair Popple, Aneesh Kumar K.V, Christophe Leroy, # Gustavo Romero, Joel Stanley, Jordan Niethe, Laurent Dufour, Michael # Roth, Oliver O'Halloran" # # * tag 'powerpc-5.4-2' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux: # powerpc/eeh: Fix eeh eeh_debugfs_break_device() with SRIOV devices # powerpc/nvdimm: use H_SCM_QUERY hcall on H_OVERLAP error # powerpc/nvdimm: Use HCALL error as the return value # selftests/powerpc: Add test case for tlbie vs mtpidr ordering issue # powerpc/mm: Fixup tlbie vs mtpidr/mtlpidr ordering issue on POWER9 # powerpc/book3s64/radix: Rename CPU_FTR_P9_TLBIE_BUG feature flag # powerpc/book3s64/mm: Don't do tlbie fixup for some hardware revisions # powerpc/pseries: Call H_BLOCK_REMOVE when supported # powerpc/pseries: Read TLB Block Invalidate Characteristics # KVM: PPC: Book3S HV: use smp_mb() when setting/clearing host_ipi flag # powerpc/mm: Fix an Oops in kasan_mmu_init() # powerpc/mm: Add a helper to select PAGE_KERNEL_RO or PAGE_READONLY # powerpc/64s: Set reserved PCR bits # powerpc: Fix definition of PCR bits to work with old binutils # powerpc/book3s64/radix: Remove WARN_ON in destroy_context() # powerpc/tm: Add tm-poison test # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-ld --version # < git log --format=%s --max-count=1 a2953204b576ea3ba4afd07b917811d50fc49778 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/linus_corenet32_smp_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- corenet32_smp_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/linus_corenet32_smp_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:204:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/base/regmap/regmap.c: In function 'regmap_raw_read': /kisskb/src/drivers/base/regmap/regmap.c:2591:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/base/regmap/regmap.c: In function '_regmap_raw_write': /kisskb/src/drivers/base/regmap/regmap.c:1852:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/sound/soc/soc-pcm.c: In function 'soc_pcm_trigger': /kisskb/src/sound/soc/soc-pcm.c:1074:5: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/sound/soc/soc-pcm.c: In function 'soc_pcm_bespoke_trigger': /kisskb/src/sound/soc/soc-pcm.c:1092:9: warning: 'ret' 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:338:21: note: 'pdeo' was declared here /kisskb/src/mm/hugetlb.c: In function 'alloc_pool_huge_page': /kisskb/src/mm/hugetlb.c:1497:5: warning: 'page' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/udf/unicode.c: In function 'udf_name_conv_char': /kisskb/src/fs/udf/unicode.c:132:8: warning: 'c' 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:248:18: warning: 'i' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c:228:19: note: 'i' was declared here /kisskb/src/drivers/usb/core/devio.c: In function 'async_completed': /kisskb/src/drivers/usb/core/devio.c:625:23: warning: 'errno' may be used uninitialized in this function [-Wuninitialized] INFO: Uncompressed kernel (size 0xd151b4) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0xe00000) Image Name: Linux-5.3.0-ga2953204b576 Created: Sun Sep 29 07:53:07 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 6192022 Bytes = 6046.90 KiB = 5.91 MiB Load Address: 00000000 Entry Point: 00000000 Completed OK # rm -rf /kisskb/build/linus_corenet32_smp_defconfig_powerpc-gcc4.6 # Build took: 0:01:58.763417
