Subject: [PATCH 2/5] x86/cpuid: Clean up <asm/cpuid/types.h>
Date: Mon, 17 Mar 2025 23:30:36 +0100 [thread overview]
Message-ID: <20250317223039.3741082-3-mingo@kernel.org> (raw)
In-Reply-To: <20250317223039.3741082-1-mingo@kernel.org>
From: Ingo Molnar <mingo@kernel.org>
- We have 0x0d, 0x9 and 0x1d as literals for the CPUID_LEAF definitions,
pick a single, consistent style of 0xZZ literals.
- Likewise, harmonize the style of the 'struct cpuid_regs' list of
registers with that of 'enum cpuid_regs_idx'. Because while computers
don't care about unnecessary visual noise, humans do.
