[ofa-general] [PATCH ofed-1.2-beta 0/5] ehca: bug fixes for kernel space

[Hoang-Nam Nguyen]

Hello Vladimir!
This is a patch set for ehca with various bug fixes (being queued for 2.6.21)
I'd like to incorporate in ofed-1.2-beta.
- reworked irq handler to avoid/reduce missed irq events
  For this I've sent a patch that you have pushed in your git tree ofed_1_2 as
  kernel_patches/fixes/ehca_2_rework_irq_handler.patch
  However I realized that it's not applicable since I created it without
  applying the previous patch. Therefore I'm sending it again. Please
  replace kernel_patches/fixes/ehca_2_rework_irq_handler.patch in your
  git tree by this new one. Sorry for this inconvenience!
  BTW: The build script does not recognize such one mistake and just
  compiles and installs without error, since nothing is broken without
  this patch.
- fix race condition/locking issues in scaling code
- allow en/disabling scaling code via module parameter
- query_port() returns LINK_UP instead UNKNOWN
- fix mismatched sync between completion handler and destroy cq
Thanks!
Nam
