fs/proc/task_mmu.c: fix buffer overflow in add_page_map()

commit 8c8296223f3abb142be8fc31711b18a704c0e7d8 upstream.

Recently we met quite a lot of random kernel panic issues after enabling
CONFIG_PROC_PAGE_MONITOR.  After debuggind we found this has something
to do with following bug in pagemap:

In struct pagemapread:

  struct pagemapread {
      int pos, len;
      pagemap_entry_t *buffer;
      bool v2;
  };

pos is number of PM_ENTRY_BYTES in buffer, but len is the size of
buffer, it is a mistake to compare pos and len in add_page_map() for
checking buffer is full or not, and this can lead to buffer overflow and
random kernel panic issue.

Correct len to be total number of PM_ENTRY_BYTES in buffer.

[akpm@linux-foundation.org: document pagemapread.pos and .len units, fix PM_ENTRY_BYTES definition]

drm/i915/lvds: ditch ->prepare special case

commit 520c41cf2fa029d1e8b923ac2026f96664f17c4b upstream.

LVDS is the first output where dpms on/off and prepare/commit don't
perfectly match. Now the idea behind this special case seems to be
that for simple resolution changes on the LVDS we don't need to stop
the pipe, because (at least on newer chips) we can adjust the panel
fitter on the fly.

There are a few problems with the current code though:
- We still stop and restart the pipe unconditionally, because the crtc
  helper code isn't flexible enough.
- We show some ugly flickering, especially when changing crtcs (this
  the crtc helper would actually take into account, but we don't
  implement the encoder->get_crtc callback required to make this work
  properly).

So it doesn't even work as advertised. I agree that it would be nice
to do resolution changes on LVDS (and also eDP) whithout blacking the
screen where the panel fitter allows to do that. But imo we should
implement this as a special case a few layers up in the mode set code,
akin to how we already detect simple framebuffer changes (and only
update the required registers with ->mode_set_base).

Until this is all in place, make our lives easier and just rip it out.

Also note that this seems to fix actual bugs with enabling the lvds
output, see:

MIPS: Expose missing pci_io{map,unmap} declarations

commit 78857614104a26cdada4c53eea104752042bf5a1 upstream.

The GENERIC_PCI_IOMAP does not depend on CONFIG_PCI so move
it to the CONFIG_MIPS symbol so it's always selected for MIPS.
This fixes the missing pci_iomap declaration for MIPS.
Moreover, the pci_iounmap function was not defined in the
io.h header file if the CONFIG_PCI symbol is not set,
but it should since MIPS is not using CONFIG_GENERIC_IOMAP.

This fixes the following problem on a allyesconfig:

drivers/net/ethernet/3com/3c59x.c:1031:2: error: implicit declaration of
function 'pci_iomap' [-Werror=implicit-function-declaration]
drivers/net/ethernet/3com/3c59x.c:1044:3: error: implicit declaration of
function 'pci_iounmap' [-Werror=implicit-function-declaration]

microblaze: Update microblaze defconfigs

commit d0e045401f268a8de6f87d65678214748b772680 upstream.

The main reason is 0-day testing system which can directly
use these defconfigs for testing.

Enable support for all xilinx drivers which Microblaze
can use and disable dependency on external rootfs.cpio.
There is only one exception which is axi ethernet driver
which still uses NO_IRQ which is not defined for Microblaze.

sound: Fix make allmodconfig on MIPS

commit d4702b189c6b951c1cb3260036ff998f719bfb62 upstream.

The compile of soundcard.c is broken on MIPS when allmodconfig is used
because of the missing MAX_DMA_CHANNELS definition.  As a simple
workaround, just add a Kconfig dependency.

sound: Fix make allmodconfig on MIPS correctly

commit a62ee234a572b4c98fe98cf5fb18e4e8b0f6e43d upstream.

Commit d4702b189c ("sound: Fix make allmodconfig on MIPS") added a
(negative) dependency on ISA_DMA_SUPPORT_BROKEN. Since that Kconfig
symbol doesn't exist, this dependency will always evaluate to true.
Apparently GENERIC_ISA_DMA_SUPPORT_BROKEN was meant to be used here.

HID: microsoft: do not use compound literal - fix build

commit 6b90466cfec2a2fe027187d675d8d14217c12d82 upstream.

In patch "HID: microsoft: fix invalid rdesc for 3k kbd" I fixed
support for MS 3k keyboards. However the added check using memcmp and
a compound statement breaks build on architectures where memcmp is a
macro with parameters.

hid-microsoft.c:51:18: error: macro "memcmp" passed 6 arguments, but takes just 3

On x86_64, memcmp is a function, so I did not see the error.

vm: add no-mmu vm_iomap_memory() stub

commit 3c0b9de6d37a481673e81001c57ca0e410c72346 upstream.

I think we could just move the full vm_iomap_memory() function into
util.h or similar, but I didn't get any reply from anybody actually
using nommu even to this trivial patch, so I'm not going to touch it any
more than required.

Here's the fairly minimal stub to make the nommu case at least
potentially work.  It doesn't seem like anybody cares, though.
