Use the generic dump_stack() instead of nds32 one because they are doing
the same thing.

Greentime Hu (4):
nds32: To implement these icache invalidation APIs since nds32 cores
don't snoop data cache. This issue is found by Guo Ren. Based on the
Documentation/core-api/cachetlb.rst and it say
We found that the original implementation will only use the built-in dtb
pointer instead of the pointer pass from bootloader. This bug is fixed
by this patch.

Greentime Hu (12):
nds32: lib: To use generic lib instead of libgcc to prevent the symbol
undefined issue.
nds32: Fix
The checking code is done in kmap_atomic() so that we don't need to
check it in update_mmu_cache() again. There is no need to implement
it for cache aliasing or cache non-aliasing versions. We can just
implement one version for both.
