staging: zcache: fix cleancache crash

2011-09-20T21:17:13+00:00

After commit c5f5c4db3938 ("staging: zcache: fix crash on high memory
swap") cleancache crashes on the first successful get.  This was caused
by a remaining virt_to_page() call in zcache_pampd_get_data_and_free()
that only gets run in the cleancache path.

The patch converts the virt_to_page() to struct page casting like was
done for other instances in c5f5c4db3938.

staging: fix comedi build when ISA_DMA_API is enabled but COMEDI_PCI is not enabled

2011-09-20T00:15:46+00:00

Fix build when CONFIG_ISA_DMA_API is enabled but
CONFIG_COMEDI_PCI[_DRIVERS] is not enabled.

Fixes these build errors:

  drivers/staging/comedi/drivers/ni_labpc.c: In function 'labpc_ai_cmd':
  drivers/staging/comedi/drivers/ni_labpc.c:1351: error: implicit declaration of function 'labpc_suggest_transfer_size'
  drivers/staging/comedi/drivers/ni_labpc.c: At top level:
  drivers/staging/comedi/drivers/ni_labpc.c:1802: error: conflicting types for 'labpc_suggest_transfer_size'
  drivers/staging/comedi/drivers/ni_labpc.c:1351: note: previous implicit declaration of 'labpc_suggest_transfer_size' was here

staging: octeon-ethernet: Add missing #includes.

2011-08-23T22:35:16+00:00

I looks like something used to implicitly include linux/interrupt.h,
and no longer does.  Fix the resulting build error by explicitly
including it.

staging: zcache: fix crash on high memory swap

2011-08-23T21:52:20+00:00

zcache_put_page() was modified to pass page_address(page) instead of the
actual page structure. In combination with the function signature changes
to tmem_put() and zcache_pampd_create(), zcache_pampd_create() tries to
(re)derive the page structure from the virtual address.  However, if the
original page is a high memory page (or any unmapped page), this
virt_to_page() fails because the page_address() in zcache_put_page()
returned NULL.

This patch changes zcache_put_page() and zcache_get_page() to pass
the page structure instead of the page's virtual address, which
may or may not exist.

2011-08-23T20:03:08+00:00

Since the arrival of kernel version 3.0 in the staging tree it
turns out compile error occurs for sparc64, powerpc, and arm
platforms. This patch fixes that issue.

gma500: kill MIPI interface types

2011-08-16T14:22:16+00:00

Kirill Shutemov found problems with the non-upstream IMG driver where the
use of extra DRM encoder/connector types caused random crashes when the DRM
layer tried to display their matching name. This removes the MIPI types
matching the changes Pauli Nieminen made to the non upstream driver set.

As Pauli points out:
" MIPI (or DSI) is protocol specification on top of LVDS serial bus. That
 makes it resonable to call MIPI connectors and encoders LVDS."

(and indeed they may also be HDMI convertors or similar when we want to
 report a more useful to end user result)
