pci/irq: let pci_device_shutdown to call pci_msi_shutdown v2
[PATCH 2/2] pci/irq: let pci_device_shutdown to call pci_msi_shutdown v2 this change | commit 23a274c8a5adafc74a66f16988776fc7dd6f6e51 | Author: Prakash, Sathya <sathya.prakash@lsi.com> | Date: Fri Mar 7 15:53:21 2008 +0530 | | [SCSI] mpt fusion: Enable MSI by default for SAS controllers | | This patch modifies the driver to enable MSI by default for all SAS chips. | | Signed-off-by: Sathya Prakash <sathya.prakash@lsi.com> | Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com> | Causes the kexec of a RHEL 5.1 kernel to fail. root casue: the rhel 5.1 kernel still uses INTx emulation. and mptscsih_shutdown doesn't call pci_disable_msi to reenable INTx on kexec path So call pci_msi_shutdown in the shutdown path to do the same thing to msix Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: Jesse Barnes <jbarnes@hobbes.lan>
