Ben Hutchings bd614669ff PCI: MSI: Restore read_msi_msg_desc(); add get_cached_msi_msg_desc() ... commit 30da552428 upstream. commit 2ca1af9aa3285c6a5f103ed31ad09f7399fc65d7 "PCI: MSI: Remove unsafe and unnecessary hardware access" changed read_msi_msg_desc() to return the last MSI message written instead of reading it from the device, since it may be called while the device is in a reduced power state. However, the pSeries platform code really does need to read messages from the device, since they are initially written by firmware. Therefore: - Restore the previous behaviour of read_msi_msg_desc() - Add new functions get_cached_msi_msg{,_desc}() which return the last MSI message written - Use the new functions where appropriate Acked-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>		2010-09-20 13:17:44 -07:00
