5f2fb52fac kbuild: rename hostprogs-y/always to hostprogs/always-y
In old days, the "host-progs" syntax was used for specifying host
programs. It was renamed to the current "hostprogs-y" in 2004.

It is typically useful in scripts/Makefile because it allows Kbuild to
selectively compile host programs based on the kernel configuration.

This commit renames like follows:

  always       ->  always-y
  hostprogs-y  ->  hostprogs

So, scripts/Makefile will look like this:

  always-$(CONFIG_BUILD_BIN2C) += ...
  always-$(CONFIG_KALLSYMS)    += ...
      ...
  hostprogs := $(always-y) $(always-m)

I think this makes more sense because a host program is always a host
program, irrespective of the kernel configuration. We want to specify
which ones to compile by CONFIG options, so always-y will be handier.

The "always", "hostprogs-y", "hostprogs-m" will be kept for backward
compatibility for a while.

3a6fb6c425 video: hyperv: hyperv_fb: Use physical memory for fb on HyperV Gen 1 VMs.
On Hyper-V, Generation 1 VMs can directly use VM's physical memory for
their framebuffers. This can improve the efficiency of framebuffer and
overall performence for VM. The physical memory assigned to framebuffer
must be contiguous. We use CMA allocator to get contiguouse physicial
memory when the framebuffer size is greater than 4MB. For size under
4MB, we use alloc_pages to achieve this.

To enable framebuffer memory allocation from CMA, supply a kernel
parameter to give enough space to CMA allocator at boot time. For
example:
    cma=130m
This gives 130MB memory to CAM allocator that can be allocated to
framebuffer. If this fails, we fall back to the old way of using
mmio for framebuffer.

382a462217 video: hyperv_fb: Fix hibernation for the deferred IO feature
fb_deferred_io_work() can access the vmbus ringbuffer by calling
fbdefio->deferred_io() -> synthvid_deferred_io() -> synthvid_update().

Because the vmbus ringbuffer is inaccessible between hvfb_suspend()
and hvfb_resume(), we must cancel info->deferred_work before calling
vmbus_close() and then reschedule it after we reopen the channel
in hvfb_resume().

31a2a32921 fbdev: remove object duplication in Makefile
The objects in $(fb-objs) $(fb-y) $(fb-m) are linked to fb.ko .

This line adds $(fb-y) to fb-objs, so the objects from $(fb-y) are
listed twice as the dependency of the module.

It works because Kbuild trims the duplicated objects from linking,
but there is no good reason to have this line.

This warning occurs because there are spaces before the tabs on these
lines. Normalize the indentation in these functions so that it is
consistent with the Linux kernel coding style and clang no longer warns.

1 warning generated.

This warning occurs because there is a space before the tab on this

so that the indentation is consistent with the Linux kernel coding
style and clang no longer warns.

This warning was introduced before the beginning of git history so no
fixes tab.

bc5e36f3d2 OMAP: DSS2: remove non-zero check on variable r
Variable r is being initialized to zero, so the check of a non-zero
rv is redundant and can be removed.

It appears that the previous case statements set r to be -EINVAL
and the "Fallthrough" comment afterwards suggested it was going
to fall through to this non-zero check but won't because of the
break statement. Remove the confusion by removing the Fallthrough
comment too.

d3d19d6fc5 fbdev: potential information leak in do_fb_ioctl()
The "fix" struct has a 2 byte hole after ->ywrapstep and the
"fix = info->fix;" assignment doesn't necessarily clear it.  It depends
on the compiler.  The solution is just to replace the assignment with an
memcpy().

e018bc28b0 console/dummycon: Remove bogus depends on from DUMMY_CONSOLE
Since commit [1] consolidated console configuration in
drivers/video/console, DUMMY_CONSOLE has always been enabled, since the
dependency is always satisfied.

There is no point in trying to allow it to be configured out, since
(a) it's tiny, and (b) if VT_CONSOLE is enabled, we must have a working
console driver by the time con_init(vt.c) runs, and only dummycon is
guaranteed to work (vgacon may be configured in, but that doesn't mean
we have a VGA device).

So just remove the fake dependency.
