riscv: Fix fully ordered LR/SC xchg[8|16]() implementations (2024-05-30 09:43:14 -0700)
----------------------------------------------------------------
RISC-V Fixes for 6.10-rc2
* A fix to avoid pt_regs aliasing with idle thread stacks on secondary
harts.
* HAVE_ARCH_HUGE_VMAP is enabled on XIP kernels, which fixes boot issues
on XIP systems with huge pages.
* An update to the uABI documentation clarifying that only scalar
misaligned accesses were grandfathered in as supported, as the vector
extension did not exist at the time the uABI was frozen.
* A fix for the recently-added byte/half atomics to avoid losing the
fully ordered decorations.
