In the uprobes handler in_ia32_syscall() is # obviously always returning false on a 64bit kernel. Use # user_64bit_mode() instead which works correctly. # # - Prevent large page splitting when ftrace flips RW/RO on the kernel # text which caused iTLB performance issues. Ftrace wants to be # converted to text_poke() which avoids the problem, but for now # allow large page preservation in the static protections check when # the change request spawns a full large page. # # - Prevent arch_dynirq_lower_bound() from returning 0 when the IOAPIC # is configured via device tree. In the device tree case the GSI 1:1 # mapping is meaningless therefore the lower bound which protects the # GSI range on ACPI machines is irrelevant. Return the lower bound # which the core hands to the function instead of blindly returning 0 # which causes the core to allocate the invalid virtual interupt # number 0 which in turn prevents all drivers from allocating and # requesting an interrupt. # # - Remove the bogus initialization of LDR and DFR in the 32bit bigsmp # APIC driver. That uses physical destination mode where LDR/DFR are # ignored, but the initialization and the missing clear of LDR caused # the APIC to be left in a inconsistent state on kexec/reboot. # # - Clear LDR when clearing the APIC registers so the APIC is in a well # defined state. # # - Initialize variables proper in the find_trampoline_placement() # code. # # - Silence GCC( build warning for the real mode part of the build" # # * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: # x86/mm/cpa: Prevent large page split when ftrace flips RW on kernel text # x86/build: Add -Wnoaddress-of-packed-member to REALMODE_CFLAGS, to silence GCC9 build warning # x86/boot/compressed/64: Fix missing initialization in find_trampoline_placement() # x86/apic: Include the LDR when clearing out APIC registers # x86/apic: Do not initialize LDR and DFR for bigsmp # uprobes/x86: Fix detection of 32-bit user mode # x86/apic: Fix arch_dynirq_lower_bound() bug for DT enabled machines # < /opt/cross/kisskb/gcc-4.6.3-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi-ld --version # < git log --format=%s --max-count=1 9f159ae07f07fc540290f21937231034f554bdd7 # < make -s -j 48 ARCH=arm O=/kisskb/build/linus_tegra_defconfig_arm CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi- tegra_defconfig # make -s -j 48 ARCH=arm O=/kisskb/build/linus_tegra_defconfig_arm CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi- /kisskb/src/kernel/rcu/srcutree.c: In function 'init_srcu_struct_fields': /kisskb/src/kernel/rcu/srcutree.c:140:32: warning: 'levelspread[<U5500>]' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/rcu/srcutree.c:88:6: note: 'levelspread[<U5500>]' was declared here /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:194:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/sched/core.c: In function 'try_to_wake_up': /kisskb/src/include/asm-generic/bitops/non-atomic.h:106:21: warning: 'cpu' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/sched/core.c:2400:6: note: 'cpu' was declared here /kisskb/src/sound/hda/hdac_regmap.c: In function 'hda_reg_write': /kisskb/src/sound/hda/hdac_regmap.c:283:16: warning: 'err' 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/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/net/mac80211/mlme.c: In function 'ieee80211_rx_mgmt_beacon': /kisskb/src/net/mac80211/mlme.c:1576:3: warning: 'pwr_level_cisco' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/net/mac80211/mlme.c:1533:6: note: 'pwr_level_cisco' was declared here /kisskb/src/drivers/usb/core/devio.c: In function 'async_completed': /kisskb/src/drivers/usb/core/devio.c:613:23: warning: 'errno' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/gpu/drm/nouveau/nvkm/subdev/top/gk104.c: In function 'gk104_top_oneinit': /kisskb/src/drivers/gpu/drm/nouveau/nvkm/subdev/top/gk104.c:104:1: warning: 'inst' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/gpu/drm/nouveau/nvkm/subdev/top/gk104.c:104:1: warning: 'type' may be used uninitialized in this function [-Wuninitialized] Completed OK # rm -rf /kisskb/build/linus_tegra_defconfig_arm # Build took: 0:02:16.670622
