Subject: [PATCH 5/6] x86/vdso: Use CFI macros in __vdso_sgx_enter_enclave()
Date: Thu, 24 Apr 2025 22:37:55 -0400	[thread overview]
Message-ID: <20250425024023.000117829@goodmis.org> (raw)
In-Reply-To: 20250425023750.669174660@goodmis.org

From: Josh Poimboeuf <jpoimboe@kernel.org>

Use the CFI macros instead of the raw .cfi_* directives to be consistent
with the rest of the VDSO asm.  It's also easier on the eyes.

No functional changes.
