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 48 ARCH=powerpc O=/kisskb/build/linus_ps3_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- ps3_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/linus_ps3_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/ipc/shm.c: In function 'ksys_shmdt': /kisskb/src/ipc/shm.c:1712:59: warning: 'file' 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: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/net/core/gen_stats.c: In function '__gnet_stats_copy_basic': /kisskb/src/net/core/gen_stats.c:156:19: warning: 'seq' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/lib/mpi/mpicoder.c: In function 'mpi_read_raw_from_sgl': /kisskb/src/lib/mpi/mpicoder.c:352:8: warning: 'buff' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/lib/rhashtable.c: In function 'rht_deferred_worker': /kisskb/src/include/linux/rhashtable.h:110:10: warning: 'next' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/lib/rhashtable.c:222:28: note: 'next' was declared here /kisskb/src/net/core/dev.c: In function 'validate_xmit_skb_list': /kisskb/src/net/core/dev.c:3597:15: warning: 'tail' may be used uninitialized in this function [-Wuninitialized] /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] /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/fs/splice.c: In function '__do_compat_sys_vmsplice': /kisskb/src/fs/splice.c:1416:8: warning: 'type' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/splice.c: In function '__do_sys_vmsplice': /kisskb/src/fs/splice.c:1390:8: warning: 'type' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/cifs/smb2pdu.c: In function 'SMB2_ioctl_init': /kisskb/src/fs/cifs/smb2pdu.c:2816:19: warning: 'in_data_buf' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/net/bluetooth/hidp/core.c: In function 'hidp_connection_add': /kisskb/src/net/bluetooth/hidp/core.c:1386:18: warning: 'session' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/net/mac80211/tx.c: In function 'ieee80211_build_hdr': /kisskb/src/net/mac80211/tx.c:2551:27: warning: 'chanctx_conf' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/net/wireless/nl80211.c: In function 'nl80211_vendor_cmd_dump': /kisskb/src/net/wireless/nl80211.c:13147:33: warning: 'wdev' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/net/wireless/nl80211.c:13117:21: warning: 'rdev' 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 Completed OK # rm -rf /kisskb/build/linus_ps3_defconfig_powerpc-gcc4.6 # Build took: 0:01:34.973912
