Bjorn Helgaas 48728e0774 x86/PCI: compute Address Space length rather than using _LEN ... ACPI _CRS Address Space Descriptors have _MIN, _MAX, and _LEN. Linux has been computing Address Spaces as [_MIN to _MIN + _LEN - 1]. Based on the tests in the bug reports below, Windows apparently uses [_MIN to _MAX]. Per spec (ACPI 4.0, Table 6-40), for _CRS fixed-size, fixed location descriptors, "_LEN must be (_MAX - _MIN + 1)", and when that's true, it doesn't matter which way we compute the end. But of course, there are BIOSes that don't follow this rule, and we're better off if Linux handles those exceptions the same way as Windows. This patch makes Linux use [_MIN to _MAX], as Windows seems to do. This effectively reverts d558b483d5 and 03db42adfe and replaces them with simpler code. https://bugzilla.kernel.org/show_bug.cgi?id=14337 (round) https://bugzilla.kernel.org/show_bug.cgi?id=15480 (truncate) Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>		15 years ago
