| Subject: [PATCH] setting irq affinity is broken in ia32 with MSI enabled |
| From: Shaohua Li <shaohua.li@intel.com> |
| |
| Setting irq affinity stops working when MSI is enabled. With MSI, move_irq |
| is empty, so we can't change irq affinity. It appears a typo in Ashok's |
| original commit for this issue. X86_64 actually is using move_native_irq. |
