hi, there is a problem using new pata drivers with an old IBM Intellistation POWER 275 (9114-275 pSeries POWER4+). These boxes are equipped with an IDE dvd-rom drive (PATA_WINBOND driver). :00:03.1 IDE interface: Symphony Labs SL82c105 (rev 05) I can report, instead, that the old ide-cd dri

[PATCH 02/32] powerpc/cell: use system_wq in cpufreq_spudemand

2011-01-03 Thread Tejun Heo
With cmwq, there's no reason to use a separate workqueue in cpufreq_spudemand. Use system_wq instead. The work items are already sync canceled on stop, so it's already guaranteed that no work is running when spu_gov_exit() is entered. Signed-off-by: Tejun Heo Cc: Arnd Bergmann Cc: linuxppc-dev

PowerPC MPC5200B ATA MWDMA regression

The therm_pm72 driver, used on the PowerMac G5 range, cannot be auto-loaded, since the driver itself creates both the device node and the driver instance. Moving the device node creation to the platform setup code and adding the necessary MODULE_DEVICE_TABLE() information allows the driver to be a

[PATCH] RapidIO: Fix hang on RapidIO doorbell queue full condition

In fsl_rio_dbell_handler, the code currently simply acknowledges the QFI queue full interrupt, but does nothing to resolve the queue full condition. Instead, it jumps to the end of the isr. When a queue full condition occurs, the isr is then re-entered immediately and continually, forever. The f
