This is caused by an ordering issue # introduced in the recent changes which skip PIT initialization when # the TSC and APIC frequencies are already known. # # - Handle malformed SRAT tables during early ACPI parsing which caused # an infinite loop anda boot hang. # # - Fix a long standing race in the affinity setting code which affects # PCI devices with non-maskable MSI interrupts. The problem is caused # by the non-atomic writes of the MSI address (destination APIC id) # and data (vector) fields which the device uses to construct the MSI # message. The non-atomic writes are mandated by PCI. # # If both fields change and the device raises an interrupt after # writing address and before writing data, then the MSI block # constructs a inconsistent message which causes interrupts to be # lost and subsequent malfunction of the device. # # The fix is to redirect the interrupt to the new vector on the # current CPU first and then switch it over to the new target CPU. # This allows to observe an eventually raised interrupt in the # transitional stage (old CPU, new vector) to be observed in the APIC # IRR and retriggered on the new target CPU and the new vector. # # The potential spurious interrupts caused by this are harmless and # can in the worst case expose a buggy driver (all handlers have to # be able to deal with spurious interrupts as they can and do happen # for various reasons). # # - Add the missing suspend/resume mechanism for the HYPERV hypercall # page which prevents resume hibernation on HYPERV guests. This # change got lost before the merge window. # # - Mask the IOAPIC before disabling the local APIC to prevent # potentially stale IOAPIC remote IRR bits which cause stale # interrupt lines after resume" # # * tag 'x86-urgent-2020-02-09' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: # x86/apic: Mask IOAPIC entries when disabling the local APIC # x86/hyperv: Suspend/resume the hypercall page for hibernation # x86/apic/msi: Plug non-maskable MSI affinity race # x86/boot: Handle malformed SRAT tables during early ACPI parsing # x86/timer: Don't skip PIT setup when APIC is disabled or in legacy mode # < /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 1a2a76c2685a29e46d7b37e752ccea7b15aa8e24 # < make -s -j 8 ARCH=powerpc O=/kisskb/build/linus_mpc512x_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- mpc512x_defconfig # make -s -j 8 ARCH=powerpc O=/kisskb/build/linus_mpc512x_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:72:12: 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/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/fs/ext4/extents.c: In function 'ext4_convert_unwritten_io_end_vec': /kisskb/src/fs/ext4/extents.c:5009:23: warning: 'ret' 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:2598:6: 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:1859:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/io_uring.c: In function '__io_sqe_files_update.isra.83': /kisskb/src/fs/io_uring.c:5749:13: warning: 'err' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/mtd/nand/raw/mpc5121_nfc.c: In function 'ads5121_select_chip': /kisskb/src/drivers/mtd/nand/raw/mpc5121_nfc.c:293:19: warning: unused variable 'mtd' [-Wunused-variable] /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 0x63819c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) Image Name: Linux-5.5.0-g1a2a76c2685a Created: Mon Feb 10 10:54:26 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3151663 Bytes = 3077.80 KiB = 3.01 MiB Load Address: 00000000 Entry Point: 00000000 Completed OK # rm -rf /kisskb/build/linus_mpc512x_defconfig_powerpc-gcc4.6 # Build took: 0:01:37.197826
