From mboxrd@z Thu Jan 1 00:00:00 1970 From: aleksey.makarov@linaro.org (Aleksey Makarov) Date: Mon, 20 Jun 2016 13:56:09 +0300 Subject: [PATCH v4 1/5] ACPI: table upgrade: use cacheable map for tables In-Reply-To: <20160620105615.15538-1-aleksey.makarov@linaro.org> References: <20160620105615.15538-1-aleksey.makarov@linaro.org> Message-ID: <20160620105615.15538-2-aleksey.makarov@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
