e.g. # list_del(&entry->list) and kfree(entry) inside free_msi_irqs() do # happen (MSI descriptors are allocated before pci_msi_setup_msi_irqs() # is called and need to be cleaned up if that fails). # # Fixes: 6b2fd7efeb88 ("PCI/MSI/PPC: Remove arch_msi_check_device()") # Cc: stable@vger.kernel.org # v3.18+ # Signed-off-by: Radu Rendec <radu.rendec@gmail.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < git log --format=%s --max-count=1 78e7b15e17ac175e7eed9e21c6f92d03d3b0a6fa # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc83xx_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- mpc83xx_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc83xx_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- arch/powerpc/boot/dts/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/dts/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 0x623b6c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) INFO: Uncompressed kernel (size 0x623b6c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) INFO: Uncompressed kernel (size 0x623b6c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) INFO: Uncompressed kernel (size 0x623b6c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) INFO: Uncompressed kernel (size 0x623b6c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) INFO: Uncompressed kernel (size 0x623b6c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) INFO: Uncompressed kernel (size 0x613454) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) INFO: Uncompressed kernel (size 0x623b6c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x700000) Image Name: Linux-4.20.0-rc1-g78e7b15e17ac Created: Fri Nov 30 01:00:14 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3123469 Bytes = 3050.26 KiB = 2.98 MiB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-4.20.0-rc1-g78e7b15e17ac Created: Fri Nov 30 01:00:14 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3153053 Bytes = 3079.15 KiB = 3.01 MiB Load Address: 00700000 Entry Point: 00700294 Image Name: Linux-4.20.0-rc1-g78e7b15e17ac Created: Fri Nov 30 01:00:14 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3153414 Bytes = 3079.51 KiB = 3.01 MiB Load Address: 00700000 Entry Point: 00700294 Image Name: Linux-4.20.0-rc1-g78e7b15e17ac Created: Fri Nov 30 01:00:15 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3153303 Bytes = 3079.40 KiB = 3.01 MiB Load Address: 00700000 Entry Point: 00700294 Image Name: Linux-4.20.0-rc1-g78e7b15e17ac Created: Fri Nov 30 01:00:15 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3152825 Bytes = 3078.93 KiB = 3.01 MiB Load Address: 00700000 Entry Point: 00700294 Image Name: Linux-4.20.0-rc1-g78e7b15e17ac Created: Fri Nov 30 01:00:15 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3153326 Bytes = 3079.42 KiB = 3.01 MiB Load Address: 00700000 Entry Point: 00700294 Image Name: Linux-4.20.0-rc1-g78e7b15e17ac Created: Fri Nov 30 01:00:15 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3153669 Bytes = 3079.75 KiB = 3.01 MiB Load Address: 00700000 Entry Point: 00700294 Completed OK # rm -rf /kisskb/build/powerpc-fixes_mpc83xx_defconfig_powerpc-gcc5 # Build took: 0:00:50.287586
