-----Original Message----- From: Toshi Kani [mailto:toshi.kani@hp.com] Sent: Friday, August 28, 2015 7:40 AM To: Williams, Dan J; Wysocki, Rafael J; Moore, Robert Cc: devel(a)acpica.org; linux-nvdimm(a)lists.01.org; linux- acpi(a)vger.kernel.org; linux-kernel(a)vger.kernel.org; Toshi Kani Subject: [PATCH]: acpica/nfit: Rename not-armed bit definition ACPI 6.0 NFIT Memory Device State Flags in Table 5-129 defines bit 3 as follows. Bit [3] set to 1 to indicate that the Memory Device is observed to be not armed prior to OSPM hand off. A Memory Device is considered armed if it is able to accept persistent writes. This bit is currently defined as ACPI_NFIT_MEM_ARMED, which can be confusing as if the Memory Device is armed when this bit is set. Change the name to ACPI_NFIT_MEM_NOT_ARMED per the spec.
