[Qemu-devel] [PATCH v2 14/23] Revert "acpi: mark PMTIMER as unlocked"

[Stefan Hajnoczi]

From: Gerd Hoffmann <address@hidden>

This reverts commit 7070e085d490c396f9237c8f10bf8b6e69cd0066.

Commit message claims locking is not needed, but that appears
to not be true, seabios ehci driver runs into timekeeping problems
with this, see
        https://bugzilla.redhat.com/show_bug.cgi?id=1322713
