* bug in AT91 MCI suspend routinesAnti Sullin2007-09-111-3/+3
| | | | | | | | | | | | This patch fixes a bug in AT91 mmc host driver, that enables the wakeup from suspend on card detection pin even if the card detect pin is not available (==0). If not card detection pin is defined, IRQ0 == FIQ gets enabled and if some activity is present on that pin, the system gets a FIQ request, that causes a crash.

* sdhci: handle data interrupts during commandPierre Ossman2007-08-232-7/+22

* mmc: ignore bad max block size in sdhciDavid Vrabel2007-08-231-5/+4

* Freezer: make kernel threads nonfreezable by defaultRafael J. Wysocki2007-07-171-5/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the freezer treats all tasks as freezable, except for the kernel threads that explicitly set the PF_NOFREEZE flag for themselves. This approach is problematic, since it requires every kernel thread to either set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't care for the freezing of tasks at all. It seems better to only require the kernel threads that want to or need to be frozen to use some freezer-related code and to remove any freezer-related code from the other (nonfreezable) kernel threads, which is done in this patch. The patch causes all kernel threads to be nonfreezable by default (ie. to have PF_NOFREEZE set by default) and introduces the set_freezable() function that should be called by the freezable kernel threads in order to unset PF_NOFREEZE. It also makes all of the currently freezable kernel threads call set_freezable(), so it shouldn't cause any (intentional) change of behaviour to appear. Additionally, it updates documentation to describe the freezing of tasks more accurately. [akpm@linux-foundation.org: build fixes] Signed-off-by: Rafael J.
