Subject: riscv: Using TOOLCHAIN_HAS_ZIHINTPAUSE marco replace zihintpause
From: Minda Chen <minda.chen@xxxxxxxxxxxxxxxx>
commit dd16ac404a685cce07e67261a94c6225d90ea7ba upstream.
Actually it is a part of Conor's
commit aae538cd03bc ("riscv: fix detection of toolchain
Zihintpause support").
It is looks like a merge issue. Samuel's
commit 0b1d60d6dd9e ("riscv: Fix build with
CONFIG_CC_OPTIMIZE_FOR_SIZE=y") do not base on Conor's commit and
revert to __riscv_zihintpause. So this patch can fix it.
