Subject: [RFC v2 3/9] x86/mm: enable BROADCAST_TLB_FLUSH on Intel, too
Date: Mon, 19 May 2025 21:02:28 -0400	[thread overview]
Message-ID: <20250520010350.1740223-4-riel@surriel.com> (raw)
In-Reply-To: <20250520010350.1740223-1-riel@surriel.com>

From: Rik van Riel <riel@fb.com>

Much of the code for Intel RAR and AMD INVLPGB is shared.

Place both under the same config option.
