[Qemu-devel] [PULL 20/20] ACPI: Remove commented-out code from HPET._CRS

[Michael S. Tsirkin]

From: "Gabriel L. Somlo" <address@hidden>

IRQNoFlags on HPET._CRS crashes WinXP because it causes the HPET
to conflict with the system timer and/or the RTC. It only occurs
on Apple hardware, and even there it is exposed fully only when
OS X is detected (via _OSI). Recent OS X versions work on QEMU
without this statement, so at this time there is no need to find
a better way to conditionally include the statement. This patch
removes the commented out (and wrong, should have been {0, 8})
statement from HPET._CRS.
