csky: Add C based string functionsTry to access RAM with the largest bit width possible, but withoutdoing unaligned accesses.A further improvement could be to use multiple read and writes as theassembly version was trying to do.Tested on a BeagleV Starlight with a SiFive U74 core, where theimprovement is noticeable.Signed-off-by: Matteo Croce Co-developed-by: Guo Ren Signed-off-by: Guo Ren List of files: /linux-6.15/arch/csky/lib/Makefile

csky: Add support for function error injectionInspired by the commit 42d038c4fb00 ("arm64: Add support for functionerror injection"), this patch supports function error injection forcsky.This patch mainly support two functions: one is regs_set_return_value()which is used to overwrite the return value; the another function isoverride_function_with_return() which is to override the probedfunction returning and jump to its caller.Test log: cd /sys/kernel/debug/fail_function/ echo sys_clone > inject echo 100 > probability echo 1 > interval ls /[ 108.644163] FAULT_INJECTION: forcing a failure.[ 108.644163] name fail_function, interval 1, probability 100, space 0, times 1[ 108.647799] CPU: 0 PID: 104 Comm: sh Not tainted 5.8.0-rc5+ #46[ 108.648384] Call Trace:[ 108.649339] [<8005eed4>] walk_stackframe+0x0/0xf0[ 108.649679] [<8005f16a>] show_stack+0x32/0x5c[ 108.649927] [<8040f9d2>] dump_stack+0x6e/0x9c[ 108.650271] [<80406f7e>] should_fail+0x15e/0x1ac[ 108.650720] [<80118ba8>] fei_kprobe_handler+0x28/0x5c[ 108.651519] [<80754110>] kprobe_breakpoint_handler+0x144/0x1cc[ 108.652289] [<8005d6da>] trap_c+0x8e/0x110[ 108.652816] [<8005ce8c>] csky_trap+0x5c/0x70-sh: can't fork: Invalid argumentSigned-off-by: Guo Ren Cc: Arnd Bergmann List of files: /linux-6.15/arch/csky/lib/Makefile
