microblaze: Guard __HAVE_ARCH macros with __KERNEL__ in string.h A polarity reversal in the __KERNEL__ guard prevents the __HAVE_ARCH flags from being defined in kernel compilation. I noticed that there's now an option for assembly-optimized versions of memcpy and memmove. I believe this may be buggy; when I turn it on, all my printk output gets smashed together, as if the newlines aren't getting copied. Signed-off-by: Steven J.

microblaze: Use simple memset implementation from lib/string.c On microblaze systems which are not using OPT_LIB_FUNCTION only simple memset is used. This function is already implemented in lib/string.c that's why it should be used instead. This change is done in respect of issue fixed by commit 33d0f96ffd73 ("lib/string.c: Use freestanding environment") where gcc-10.x moved -ftree-loop-distribute-patterns optimization is to O2 optimization level. This optimization causes GCC to convert the while loop in memset.c into a call to memset. So This optimization is transforming a loop in a memset/memcpy into a call to the function itself. This makes the memset implementation as recursive. Based on fix above -ffreestanding was used and it needs to be used on Microblaze too but the patch is not adding this flag it removes simple implementation to cause that generic implementation is used where this flag is already setup.

microblaze: Use simple memmove/memcpy implementation from lib/string.c This is based on previous commit ("microblaze: Use simple memset implementation from lib/string.c") where generic memset implementation is used when OPT_LIB_FUNCTION is not defined. The same change can be done for memset/memcpy implementation where doesn't make sense to have generic implementation in architecture code.
