It # also allows GCC to keep the saved ksp_limit in an nonvolatile reg. # # This is inspired from S390 arch. Several other arches do more or # less the same. The way sparc arch does seems odd thought. # # Signed-off-by: Christophe Leroy # Signed-off-by: Michael Ellerman # --- # # v2: no change. # v3: no change. # v4: # - comment reminding the purpose of the inline asm block. # - added r2 as clobbered reg # v5: # - Limiting the change to PPC32 for now. # - removed r2 from the clobbered regs list (on PPC32 r2 points to current all the time) # - Removed patch 1 and merged ksp_limit handling in here. # v6: # - Rebase on top of merge-test (ca6e327fefb2). # - Remove the ksp_limit stuff as it's doesn't exist anymore. # # v7: # mpe: # - Enable for 64-bit too. This all in-kernel code calling in-kernel # code, and must use the kernel TOC. # - Use named parameters for the inline asm. # - Reformat inline asm. # - Mark as always_inline. # - Drop unused ret from call_do_softirq(), add r3 as clobbered. # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 5ad0e6cf98ac177bdc3d162dda4af5253b0f0d78 # < make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc83xx_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- mpc83xx_defconfig # < make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc83xx_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc83xx_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc83xx_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/block/genhd.c: In function 'diskstats_show': /kisskb/src/block/genhd.c:1313:1: warning: the frame size of 1160 bytes is larger than 1024 bytes [-Wframe-larger-than=] } ^ INFO: Uncompressed kernel (size 0x7e4958) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x800000) INFO: Uncompressed kernel (size 0x7e4958) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x800000) INFO: Uncompressed kernel (size 0x7e4958) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x800000) INFO: Uncompressed kernel (size 0x7e4958) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x800000) INFO: Uncompressed kernel (size 0x7e4958) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x800000) INFO: Uncompressed kernel (size 0x7e4958) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x800000) INFO: Uncompressed kernel (size 0x7d4348) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x800000) INFO: Uncompressed kernel (size 0x7e4958) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x800000) Image Name: Linux-5.12.0-rc2-g5ad0e6cf98ac Created: Sun Mar 21 18:02:26 2021 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3608290 Bytes = 3523.72 KiB = 3.44 MiB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-5.12.0-rc2-g5ad0e6cf98ac Created: Sun Mar 21 18:02:26 2021 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3638367 Bytes = 3553.09 KiB = 3.47 MiB Load Address: 00800000 Entry Point: 00800294 Image Name: Linux-5.12.0-rc2-g5ad0e6cf98ac Created: Sun Mar 21 18:02:27 2021 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3638669 Bytes = 3553.39 KiB = 3.47 MiB Load Address: 00800000 Entry Point: 00800294 Image Name: Linux-5.12.0-rc2-g5ad0e6cf98ac Created: Sun Mar 21 18:02:27 2021 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3638339 Bytes = 3553.07 KiB = 3.47 MiB Load Address: 00800000 Entry Point: 00800294 Image Name: Linux-5.12.0-rc2-g5ad0e6cf98ac Created: Sun Mar 21 18:02:27 2021 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3638276 Bytes = 3553.00 KiB = 3.47 MiB Load Address: 00800000 Entry Point: 00800294 Image Name: Linux-5.12.0-rc2-g5ad0e6cf98ac Created: Sun Mar 21 18:02:27 2021 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3638054 Bytes = 3552.79 KiB = 3.47 MiB Load Address: 00800000 Entry Point: 00800294 Image Name: Linux-5.12.0-rc2-g5ad0e6cf98ac Created: Sun Mar 21 18:02:27 2021 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3638427 Bytes = 3553.15 KiB = 3.47 MiB Load Address: 00800000 Entry Point: 00800294 Completed OK # rm -rf /kisskb/build/powerpc-next_mpc83xx_defconfig_powerpc-gcc4.9 # Build took: 0:00:36.408061
