There are reasons for why RCU is used here. Using spinlock here will break specific acpi_os_read_memory()/acpi_os_write_memory() users. So this patchset is not correct, please ignore. Thanks -Lv > From: Zheng, Lv > Sent: Thursday, October 23, 2014 10:12 AM > > It is reported that there is a

It is reported that there is a performance issue in the ACPICA OSL implementation around memory mappings. On the reported platforms, there is a debugging facility implemented in the ACPI namespace using circular logging buffer: Name (DPTR, 0x3AFEB000) Name (EPTR, 0x3AFFB000)
