So there is no point in creating a cache for 4 entries # page tables. # # Also, with HW assistance the entries must be 4k aligned, the 8xx # drops the last 12 bits. Redefine HUGEPD_SHIFT_MASK to mask them out. # # Calculate PTE_T_ORDER using the size of pte_basic_t instead of pte_t. # # In 16k mode, define a specific set_huge_pte_at() function which writes # the pte in a single entry instead of using set_pte_at() which writes # 4 identical entries. Define set_pte_filter() inline otherwise GCC # doesn't inline it anymore because it is now used twice, and that gives # a pretty suboptimal code because of pte_t being a struct of 4 entries. # This function is also used for 512k pages which only require one entry # as well allthough replicating it four times is harmless as 512k pages # entries are spread every 128 bytes in the table. # # Fixes: 22569b881d37 ("powerpc/8xx: Enable 8M hugepage support with HW assistance") # Cc: stable@vger.kernel.org # v5.0+ # 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/e744db1529271d11a3fdcdf641617846907b6ffd.1580997012.git.christophe.leroy@c-s.fr # < /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 5b82a04d57b60f48dc7f73763941a6542ad1cf16 # < make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-fixes_44x_katmai_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- 44x/katmai_defconfig # make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-fixes_44x_katmai_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:72:12: 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/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/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 /kisskb/src/fs/io_uring.c: In function '__io_sqe_files_update.isra.74': /kisskb/src/fs/io_uring.c:5713:13: warning: 'err' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/arch/powerpc/boot/dts/katmai.dts:322.26-361.5: Warning (pci_bridge): /plb/pciex@d00000000: node name is not "pci" or "pcie" /kisskb/src/arch/powerpc/boot/dts/katmai.dts:363.26-402.5: Warning (pci_bridge): /plb/pciex@d20000000: node name is not "pci" or "pcie" /kisskb/src/arch/powerpc/boot/dts/katmai.dts:404.26-443.5: Warning (pci_bridge): /plb/pciex@d40000000: node name is not "pci" or "pcie" arch/powerpc/boot/dts/katmai.dtb: Warning (pci_device_bus_num): Failed prerequisite 'pci_bridge' INFO: Uncompressed kernel (size 0x455c08) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) Image Name: Linux-5.5.0-g5b82a04d57b6 Created: Sun Feb 9 20:43:40 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2186924 Bytes = 2135.67 KiB = 2.09 MiB Load Address: 00500000 Entry Point: 005014c0 Completed OK # rm -rf /kisskb/build/powerpc-fixes_44x_katmai_defconfig_powerpc-gcc4.6 # Build took: 0:00:38.391015
