Message-Id: <1463674518-22477-2-git-send-email-aleksey.makarov@linaro.org> Date: Thu, 19 May 2016 19:15:12 +0300 From: Aleksey Makarov <aleksey.makarov@...aro.org> To: Russell King <linux@....linux.org.uk>, "Rafael J . Wysocki" <rjw@...ysocki.net>, Len Brown <lenb@...nel.org> Cc: linux-acpi@...r.kernel.org, linux-arm-kernel@...ts.infradead.org, linux-kernel@...r.kernel.org, Aleksey Makarov <aleksey.makarov@...aro.org>, Graeme Gregory <graeme.gregory@...aro.org>, Jon Masters <jcm@...hat.com>, "Zheng, Lv" <lv.zheng@...el.com>, Mark Rutland <mark.rutland@....com> Subject: [PATCH v2 1/5] ACPI: table upgrade: use cacheable map for tables The new memory allocated in acpi_table_initrd_init() is used to copy the upgraded tables to it. So it should be mapped with early_memunmap() instead of early_ioremap(). This is critical for ARM.
