And the fact that even the kernel VM # maintainers apparently didn't catch that this "fix" is not a fix any # more pretty much proves the point that people can't be expected to # understand the implications of the question. # # It may well be the case that we could improve things further, and that # __thp_get_unmapped_area() should take the mapping randomization into # account even for 64-bit kernels. Maybe we should not be so eager to use # THP mappings. # # But in no case should this be a kernel config option. # # Cc: Rafael Aquini # Cc: Andrew Morton # Cc: Jiri Slaby # Cc: Suren Baghdasaryan # Cc: Matthew Wilcox (Oracle) # Signed-off-by: Linus Torvalds # < /opt/cross/kisskb/korg/gcc-8.5.0-nolibc/mips-linux/bin/mips-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.5.0-nolibc/mips-linux/bin/mips-linux-ld --version # < git log --format=%s --max-count=1 14d7c92f8df9c0964ae6f8b813c1b3ac38120825 # make -s -j 160 ARCH=mips O=/kisskb/build/linus_ip22_defconfig_mips-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/mips-linux/bin/mips-linux- ip22_defconfig # < make -s -j 160 ARCH=mips O=/kisskb/build/linus_ip22_defconfig_mips-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/mips-linux/bin/mips-linux- help # make -s -j 160 ARCH=mips O=/kisskb/build/linus_ip22_defconfig_mips-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/mips-linux/bin/mips-linux- olddefconfig # make -s -j 160 ARCH=mips O=/kisskb/build/linus_ip22_defconfig_mips-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/mips-linux/bin/mips-linux- /kisskb/src/arch/mips/sgi-ip22/ip22-berr.c:89:6: warning: no previous prototype for 'ip22_be_interrupt' [-Wmissing-prototypes] void ip22_be_interrupt(int irq) ^~~~~~~~~~~~~~~~~ /kisskb/src/arch/mips/sgi-ip22/ip22-berr.c:113:13: warning: no previous prototype for 'ip22_be_init' [-Wmissing-prototypes] void __init ip22_be_init(void) ^~~~~~~~~~~~ /kisskb/src/arch/mips/sgi-ip22/ip22-gio.c:249:6: warning: no previous prototype for 'ip22_gio_set_64bit' [-Wmissing-prototypes] void ip22_gio_set_64bit(int slotno) ^~~~~~~~~~~~~~~~~~ /kisskb/src/arch/mips/sgi-ip22/ip22-gio.c:398:12: warning: no previous prototype for 'ip22_gio_init' [-Wmissing-prototypes] int __init ip22_gio_init(void) ^~~~~~~~~~~~~ /kisskb/src/arch/mips/sgi-ip22/ip22-time.c:119:18: warning: no previous prototype for 'indy_8254timer_irq' [-Wmissing-prototypes] void __irq_entry indy_8254timer_irq(void) ^~~~~~~~~~~~~~~~~~ /kisskb/src/drivers/scsi/sgiwd93.c:173:6: warning: no previous prototype for 'sgiwd93_reset' [-Wmissing-prototypes] void sgiwd93_reset(unsigned long base) ^~~~~~~~~~~~~ Completed OK # rm -rf /kisskb/build/linus_ip22_defconfig_mips-gcc8 # Build took: 0:01:44.448487
