Subject: [PATCH AUTOSEL 6.14 14/30] riscv: Provide all alternative macros all the time
Date: Mon, 21 Apr 2025 22:15:34 -0400	[thread overview]
Message-ID: <20250422021550.1940809-14-sashal@kernel.org> (raw)
In-Reply-To: <20250422021550.1940809-1-sashal@kernel.org>

From: Andrew Jones <ajones@ventanamicro.com>

[ Upstream commit fb53a9aa5f5b8bf302f3260a7f1f5a24345ce62a ]

We need to provide all six forms of the alternative macros
(ALTERNATIVE, ALTERNATIVE_2, _ALTERNATIVE_CFG, _ALTERNATIVE_CFG_2,
__ALTERNATIVE_CFG, __ALTERNATIVE_CFG_2) for all four cases derived
from the two ifdefs (RISCV_ALTERNATIVE, __ASSEMBLY__) in order to
ensure all configs can compile. Define this missing ones and ensure
all are defined to consume all parameters passed.
