Restore the original image by # relocating it back to the kernel virtual base address. # # This works because during build vmlinux is linked with an expected # virtual runtime address of KERNELBASE. # # Fixes: 6a9c930bd775 ("powerpc/prom_init: Add the ESM call to prom_init") # Signed-off-by: Thiago Jung Bauermann # Tested-by: Ram Pai # [mpe: Add IS_ENABLED() to fix the CONFIG_RELOCATABLE=n build] # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/20190911163433.12822-1-bauerman@linux.ibm.com # < /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 83654d1d047c98341f1f4472d31c189b3bf0ebe7 # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_44x_ebony_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- 44x/ebony_defconfig # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_44x_ebony_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/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: 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/drivers/tty/serial/8250/8250_core.c: In function 'univ8250_release_irq': /kisskb/src/drivers/tty/serial/8250/8250_core.c:248:18: warning: 'i' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c:228:19: note: 'i' was declared here INFO: Uncompressed kernel (size 0x4ec17c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) INFO: Uncompressed kernel (size 0x4ec17c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) Image Name: Linux-5.4.0-rc2-g83654d1d047c Created: Mon Oct 28 19:24:27 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2506543 Bytes = 2447.80 KiB = 2.39 MiB Load Address: 00500000 Entry Point: 005000c8 Completed OK # rm -rf /kisskb/build/powerpc-fixes_44x_ebony_defconfig_powerpc-gcc4.6 # Build took: 0:00:32.364794
