x86: Stop including in two asm header files

2011-03-29T07:37:42Z

Stop including in x86 header files which don't need it. This will let the compiler complain when this header is not included by source files when it should, so that contributors can fix the problem before building on other architectures starts to fail. Credits go to Geert for the idea. Signed-off-by: Jean Delvare Cc: James E.J.

[SCSI] qla4xxx: Use polling mode for disable interrupt mailbox completion

2011-03-23T17:53:09Z

Disable Interrupt MBX completion will disable the interrupt on successful completion. Fixed the bug where driver was waiting for Interrupt to come in for its completion. Now driver will poll for disable interrupt MBX completion. Signed-off-by: Sarang Radke Signed-off-by: Vikas Chaudhary Reviewed-by: Mike Christie Signed-off-by: James Bottomley

[SCSI] Revert "[SCSI] Retrieve the Caching mode page"

2011-03-23T17:53:09Z

This reverts commit 24d720b726c1a85f1962831ac30ad4d2ef8276b1. Previously we thought there was little possibility that devices would crash with this, but some have been found. Reported-by: Alan Stern Cc: Luben Tuikov Signed-off-by: James Bottomley

[SCSI] bnx2fc: IO completion not processed due to missed wakeup

2011-03-23T17:53:06Z

Driver does not detect a new CQE (completion queue entry) if a thread receives the wakup when it is in TASK_RUNNING state. Fix is to set the state to TASK_INTERRUPTIBLE while holding the fp_work_lock. Also, Use __set_current_task() since it is now set inside a spinlock with synchronization. Two other related optimizations: 1. After we exit the while (!kthread_should_stop()) loop, use __set_current_state() since synchronization is no longer needed. 2. Remove set_current_state(TASK_RUNNING) after schedule() since it should always be TASK_RUNNING after schedule().
