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/korg/gcc-8.1.0-nolibc/m68k-linux/bin/m68k-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/m68k-linux/bin/m68k-linux-ld --version # < git log --format=%s --max-count=1 1a2a76c2685a29e46d7b37e752ccea7b15aa8e24 # < make -s -j 80 ARCH=m68k O=/kisskb/build/linus_m68k-defconfig_m68k CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/m68k-linux/bin/m68k-linux- defconfig # make -s -j 80 ARCH=m68k O=/kisskb/build/linus_m68k-defconfig_m68k CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/m68k-linux/bin/m68k-linux- In file included from /kisskb/src/arch/m68k/include/asm/amigayle.h:21, from /kisskb/src/arch/m68k/include/asm/io_mm.h:59, from /kisskb/src/arch/m68k/include/asm/io.h:8, from /kisskb/src/include/linux/clocksource.h:21, from /kisskb/src/arch/m68k/amiga/config.c:20: /kisskb/src/arch/m68k/amiga/config.c: In function 'amiga_identify': /kisskb/src/arch/m68k/include/asm/amigahw.h:42:50: warning: this statement may fall through [-Wimplicit-fallthrough=] #define AMIGAHW_SET(name) (amiga_hw_present.name = 1) ~~~~~~~~~~~~~~~~~~~~~~~^~~~ /kisskb/src/arch/m68k/amiga/config.c:223:3: note: in expansion of macro 'AMIGAHW_SET' AMIGAHW_SET(PCMCIA); ^~~~~~~~~~~ /kisskb/src/arch/m68k/amiga/config.c:224:2: note: here case AMI_500: ^~~~ /kisskb/src/arch/m68k/mvme147/config.c: In function 'mvme147_hwclk': /kisskb/src/arch/m68k/mvme147/config.c:175:2: warning: #warning check me!
