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 48 ARCH=powerpc O=/kisskb/build/powerpc-next_83xx_mpc832x_rdb_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 83xx/mpc832x_rdb_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_83xx_mpc832x_rdb_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- arch/powerpc/boot/mpc832x_rdb.dtb: Warning (interrupts_property): /qe@e0100000/mdio@3120/ethernet-phy@0:#interrupt-cells: size is (4), expected multiple of 8 arch/powerpc/boot/mpc832x_rdb.dtb: Warning (interrupts_property): /qe@e0100000/mdio@3120/ethernet-phy@4:#interrupt-cells: size is (4), expected multiple of 8 INFO: Uncompressed kernel (size 0x5a153c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x590e24) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-4.19.0-rc3-g0823c68b054b Created: Thu Sep 20 02:51:14 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2838391 Bytes = 2771.87 KiB = 2.71 MiB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-4.19.0-rc3-g0823c68b054b Created: Thu Sep 20 02:51:14 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2862513 Bytes = 2795.42 KiB = 2.73 MiB Load Address: 00600000 Entry Point: 006001f4 Completed OK # rm -rf /kisskb/build/powerpc-next_83xx_mpc832x_rdb_defconfig_powerpc-gcc5 # Build took: 0:00:45.603193
