From: Rafael J. Wysocki Date: Tue, 8 Feb 2011 22:37:42 +0000 (+0100) Subject: ACPI: Change acpi_ioremap_lock into a mutex X-Git-Tag: v2.6.39-rc1~90^2~11^2~5 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7bbb890358b96cb6f77adc6815f2072bdf813d5d;p=pandora-kernel.git ACPI: Change acpi_ioremap_lock into a mutex There's no reason why acpi_ioremap_lock has to be a spinlock, because all of the functions it is used in may sleep anyway and there's no reason why it should be locked with interrupts off. Use a mutex instead (that's going to allow us to put some more operations under the lock later). Signed-off-by: Rafael J. Wysocki --- Reading git-diff-tree failed
