--- Comment #4 from Suresh B Siddha <[email protected]> 2009-10-21 00:30:14 --- Instead of from start to start+ACPI_SYSTEM_REGION_WINDOW_SIZE, we should map only from start to 4k_roundedown(start+ACPI_SYSTEM_REGION_WINDOW_SIZE). Though we are in the same operation region, this region is being chopped into sub portions used by multiple ACPI entities. And mapping up to start+ACPI_SYSTEM_REGION_WINDOW_SIZE is going beyond the 4k boundary and checks in the ioremap() complains that we are trying to map beyond one of those sub portions (these subportions are registered in the resource tree as separate entities). Sub-portion in one of the reports we saw was ACPI non-volatile storage. Mapping upto just the 4k boundary avoids the ioremap() request potentially crossing a resource entity. -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. ------------------------------------------------------------------------------ Come build with us!
