      Staging: iio: Make IIO depend on GENERIC_HARDIRQS · 928f9111
      由 Geert Uytterhoeven 提交于 
      On m68k (which doesn't support generic hardirqs yet):

Hence IIO_TRIGGER should depend on GENERIC_HARDIRQS.
But as IIO_TRIGGER and IIO_RING_BUFFER form a maze of dependencies and selects,
just make the whole IIO subsystem depend on GENERIC_HARDIRQS.

This dependency also covers !S390, so that one can be removed again.

      Staging: mei: fix suspend failure · a534bb6e
      由 Tomas Winkler 提交于 
      wait_event_interruptible_timeout return value was wrongly used.
The remaining timeout was used as the error code.
This fix translated wait_event_interruptible_timeout return value
into error code that can be propagated.

      Staging: Comedi: Build only on arches providing PAGE_KERNEL_NOCACHE · 6fab3e1f
      由 Ralf Baechle 提交于 
      On architectures that don't define PAGE_KERNEL_NOCACHE, the Comedi driver turns
into tragedy:

  CC [M]  drivers/staging/comedi/drivers.o
drivers/staging/comedi/drivers.c: In function ‘comedi_buf_alloc’:
drivers/staging/comedi/drivers.c:505:41: error: ‘PAGE_KERNEL_NOCACHE’ undeclared (first use in this function)
drivers/staging/comedi/drivers.c:505:41: note: each undeclared identifier is rep orted only once for each function it appears in
make[3]: *** [drivers/staging/comedi/drivers.o] Error 1

Restrict the driver to only those architectures that define PAGE_KERNEL_NOCACHE.

PAGE_KERNEL_NOCACHE is a kludge - some system architectures such as SGI IP27
are even uable to offer uncached operation - at least in the way an unwitting
driver might assume.  I haven't looked in details how the driver is using
the area vmaped with PAGE_KERNEL_NOCACHE but maybe doing it XFS-style using
cached memory and the flush_kernel_vmap_range / invalidate_kernel_vmap_range
APIs in conjunction with the DMA API is a practical alternative.

      Staging: fix more iio builds when IIO_RING_BUFFER is not enabled · 89089158
      由 Randy Dunlap 提交于 
      Fix lots more build errors in staging/iio when CONFIG_IIO_RING_BUFFER
is not enabled by moving enums and defines outside of the
CONFIG_IIO_RING_BUFFER ifdef block.
