mips: always link byteswap helpers into decompressor

2021-07-20T14:00:41+00:00

[ Upstream commit cddc40f5617e53f97ef019d5b29c1bd6cbb031ec ] My series to clean up the unaligned access implementation across architectures caused some mips randconfig builds to fail with: mips64-linux-ld: arch/mips/boot/compressed/decompress.o: in function `decompress_kernel': decompress.c:(.text.decompress_kernel+0x54): undefined reference to `__bswapsi2' It turns out that this problem has already been fixed for the XZ decompressor but now it also shows up in (at least) LZO and LZ4. From my analysis I concluded that the compiler could always have emitted those calls, but the different implementation allowed it to make otherwise better decisions about not inlining the byteswap, which results in the link error when the out-of-line code is missing. While it could be addressed by adding it to the two decompressor implementations that are known to be affected, but as this only adds 112 bytes to the kernel, the safer choice is to always add them.

[ Upstream commit 23c64447b3538a6f34cb38aae3bc19dc1ec53436 ] The original clock (3 MHz) is too fast for the clocksource, there will be a chance that the system may get stuck.

MIPS:DTS:Fix label name and interrupt number of ohci for Loongson-2K

2021-04-23T11:41:03+00:00

from Loongson-2K1000 user manual know that under pci bus the device num is 4, function number is 2 and register is 0x2200 is ohci. the ohci interrupt number is 51. because Loongson-2K1000 has 64 interrupt sources, 0-31 correspond to the device tree liointc0 device node, and the other correspond to liointc1 node. so it should be number 19 correspon to liointc1.

This patch replaces the "open-coded" -pg compile flag with a CC_FLAGS_FTRACE makefile variable which architectures can override if a different option should be used for code generation. Signed-off-by: zhaoxiao Signed-off-by: Thomas Bogendoerfer
