Subject: [PATCH v2 6/7] Revert "x86/apic/msi: Enable PCI/IMS"
Date: Wed, 10 Apr 2024 17:13:06 -0500	[thread overview]
Message-ID: <20240410221307.2162676-7-helgaas@kernel.org> (raw)
In-Reply-To: <20240410221307.2162676-1-helgaas@kernel.org>

From: Bjorn Helgaas <bhelgaas@google.com>

This reverts commit 6e24c887732901140f4e82ba2315c2e15f06f1d6.

IMS (Interrupt Message Store) support appeared in v6.2, but there are no
users yet.

Remove it for now.  We can add it back when a user comes along.
