Merge patch series "riscv: enable EFFICIENT_UNALIGNED_ACCESS and DCACHE_WORD_ACCESS"

Merge patch series "riscv: enable EFFICIENT_UNALIGNED_ACCESS and DCACHE_WORD_ACCESS"
Jisheng Zhang <jszhang@kernel.org> says:
Some riscv implementations such as T-HEAD's C906, C908, C910 and C920 support efficient unaligned access, for performance reason we want to enable HAVE_EFFICIENT_UNALIGNED_ACCESS on these platforms. To avoid performance regressions on non efficient unaligned access platforms, HAVE_EFFICIENT_UNALIGNED_ACCESS can't be globally selected.
To solve this problem, runtime code patching based on the detected speed is a good solution. But that's not easy, it involves lots of work to modify vairous subsystems such as net, mm, lib and so on. This can be done step by step.
So let's take an easier solution: add support to efficient unaligned access and hide the support under NONPORTABLE.
patch1 introduces RISCV_EFFICIENT_UNALIGNED_ACCESS which depends on NONPORTABLE, if users know during config time that the kernel will be only run on those efficient unaligned access hw platforms, they can enable it. Obviously, generic unified kernel Image shouldn't enable it.
patch2 adds support DCACHE_WORD_ACCESS when MMU and RISCV_EFFICIENT_UNALIGNED_ACCESS.
Below test program and step shows how much performance can be improved:
$ cat tt.c #include <sys/types.h> #include <sys/stat.h> #include <unistd.h>
#define ITERATIONS 1000000
#define PATH "123456781234567812345678123456781"
int main(void) { unsigned long i; struct stat buf;
for (i = 0; i < ITERATIONS; i++) stat(PATH, &buf);
return 0; }
$ gcc -O2 tt.c $ touch 123456781234567812345678123456781 $ time ./a.out
Per my test on T-HEAD C910 platforms, the above test performance is improved by about 7.5%.

riscv: select DCACHE_WORD_ACCESS for efficient unaligned access HW
DCACHE_WORD_ACCESS uses the word-at-a-time API for optimised string comparisons in the vfs layer.
This patch implements support for load_unaligned_zeropad in much the same way as has been done for arm64.
Here is the test program and step:
$ cat tt.c #include <sys/types.h> #include <sys/stat.h> #include <unistd.h>
#define ITERATIONS 1000000
#define PATH "123456781234567812345678123456781"
