Subject: [PATCH v4 08/15] powerpc: Implement ARCH_HAS_KERNEL_FPU_SUPPORT
Date: Fri, 29 Mar 2024 00:18:23 -0700	[thread overview]
Message-ID: <20240329072441.591471-9-samuel.holland@sifive.com> (raw)
In-Reply-To: <20240329072441.591471-1-samuel.holland@sifive.com>

PowerPC provides an equivalent to the common kernel-mode FPU API, but in
a different header and using different function names. The PowerPC API
also requires a non-preemptible context. Add a wrapper header, and
export the CFLAGS adjustments.
