Re: [PATCH v2 1/2] riscv: introduce RISCV_EFFICIENT_UNALIGNED_ACCESS

[Qingfang DENG]

Hi,

You may as well remove the -mstrict-align CFLAGS in the Makefile, if
this option is enabled:

--- a/arch/riscv/Makefile
+++ b/arch/riscv/Makefile

 # unaligned accesses.  While unaligned accesses are explicitly allowed in the
 # RISC-V ISA, they're emulated by machine mode traps on all extant
 # architectures.  It's faster to have GCC emit only aligned accesses.
