That inline function was simply masking # out the value of r1. # # In that commit, it was changed to using current_stack_pointer() (since # renamed current_stack_frame()), which is a heavier function as it is # an outline assembly function which cannot be inlined and which reads # the content of the stack at 0(r1). # # Convert to using current_stack_pointer for geting r1 and masking out # its value to obtain the base address of the stack pointer as before. # # Fixes: 7306e83ccf5c ("powerpc: Don't use CURRENT_THREAD_INFO to find the stack") # Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/a37e699e7ab897742c07b6838a08af33bc9217e3.1579849665.git.christophe.leroy@c-s.fr # < /opt/cross/kisskb/gcc-4.6.3-nolibc/i386-linux/bin/i386-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/i386-linux/bin/i386-linux-ld --version # < git log --format=%s --max-count=1 031d94b0f4799478367ec10babdd755123142ed6 # < make -s -j 24 ARCH=i386 O=/kisskb/build/powerpc-next_i386-allnoconfig_i386 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/i386-linux/bin/i386-linux- allnoconfig # make -s -j 24 ARCH=i386 O=/kisskb/build/powerpc-next_i386-allnoconfig_i386 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/i386-linux/bin/i386-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/arch/x86/kernel/e820.c: In function 'e820__setup_pci_gap': /kisskb/src/arch/x86/kernel/e820.c:665:16: warning: 'gapstart' may be used uninitialized in this function [-Wuninitialized] Completed OK # rm -rf /kisskb/build/powerpc-next_i386-allnoconfig_i386 # Build took: 0:00:34.715970
