But # currently, the kernel returns '-EEXIST' if we try to register without # uregistering it first. This could expose the system to racing issues # while unregistering and registering FADump from userspace during udev # events. Spare the userspace of this and let it be taken care of in the # kernel space for a simpler interface. # # Since this change, running 'echo 1 > /sys/kernel/fadump_registered' # would result in re-regisering (unregistering and registering) FADump, # if it was already registered. # # Signed-off-by: Hari Bathini # Acked-by: Mahesh Salgaonkar # Signed-off-by: Michael Ellerman # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < git log --format=%s --max-count=1 0823c68b054bca9dc321adea829af5cf36afb30b # < make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next_85xx_mpc85xx_cds_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 85xx/mpc85xx_cds_defconfig # make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next_85xx_mpc85xx_cds_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- arch/powerpc/boot/mpc8555cds.dtb: Warning (pci_device_bus_num): /pci@e0008000/i8259@19000:bus-range: PCI bus number 1 out of range, expected (0 - 0) arch/powerpc/boot/mpc8541cds.dtb: Warning (pci_device_bus_num): /pci@e0008000/i8259@19000:bus-range: PCI bus number 1 out of range, expected (0 - 0) INFO: Uncompressed kernel (size 0x4f0808) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) INFO: Uncompressed kernel (size 0x4f0808) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) INFO: Uncompressed kernel (size 0x4f0808) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) INFO: Uncompressed kernel (size 0x4e011c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) Image Name: Linux-4.19.0-rc3-g0823c68b054bc Created: Thu Sep 20 02:47:10 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2575028 Bytes = 2514.68 KiB = 2.46 MiB Load Address: 00500000 Entry Point: 0050020c Image Name: Linux-4.19.0-rc3-g0823c68b054bc Created: Thu Sep 20 02:47:10 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2575029 Bytes = 2514.68 KiB = 2.46 MiB Load Address: 00500000 Entry Point: 0050020c Image Name: Linux-4.19.0-rc3-g0823c68b054bc Created: Thu Sep 20 02:47:10 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2551120 Bytes = 2491.33 KiB = 2.43 MiB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-4.19.0-rc3-g0823c68b054bc Created: Thu Sep 20 02:47:10 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2576102 Bytes = 2515.72 KiB = 2.46 MiB Load Address: 00500000 Entry Point: 0050020c Completed OK # rm -rf /kisskb/build/powerpc-next_85xx_mpc85xx_cds_defconfig_powerpc-gcc5 # Build took: 0:00:16.757822
