bf4afc53b7 Convert 'alloc_obj' family to use the new default GFP_KERNEL argument
This was done entirely with mindless brute force, using

    git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
        xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'

to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.

Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.

For the same reason the 'flex' versions will be done as a separate
conversion.

69050f8d6d treewide: Replace kmalloc with kmalloc_obj for non-scalar types
This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:

Single allocations:	kmalloc(sizeof(TYPE), ...)
are replaced with:	kmalloc_obj(TYPE, ...)

Array allocations:	kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with:	kmalloc_objs(TYPE, COUNT, ...)

Flex array allocations:	kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with:	kmalloc_flex(*PTR, FAM, COUNT, ...)

(where TYPE may also be *VAR)

The resulting allocations no longer return "void *", instead returning
"TYPE *".

152609795d fbcon: Increase maximum font width x height to 64 x 128
By using bitmaps we actually support whatever size we would want, but
the console currently limits fonts to 64x128 (which gives 60x16 text on
4k screens), so we don't need more for now, and we can easily increase
later.

12b8de566f video/sticore: Store ROM device in STI struct
Store the ROM's parent device in each STI struct, so we can associate
the STI framebuffer with a device.

The new field will eventually replace the fbdev subsystem's info field,
which the function fb_is_primary_device() currently requires to detect
the firmware's output. By using the device instead of the framebuffer
info, a later patch can generalize the helper for use in non-fbdev code.

99ef0c67bc sticon/parisc: Fix STI console on 64-bit only machines
Fix the STI console to be able to execute either the 64-bit STI ROM code
or the 32-bit STI ROM code.

This is necessary on 64-bit only machines (e.g. C8000 workstation) which
otherwise won't show the STI text console with HP graphic cards like
Visualize-FX5/FX10/FXe.

Note that when calling 32-bit code from a 64-bit kernel one needs to
copy contents on the CPU stack from high memory down below the 4GB
limit.

ededd9d278 sticon/parisc: Allow 64-bit STI calls in PDC firmware abstration
Some 64-bit machines require us to call the STI ROM in 64-bit mode, e.g.
with the VisFXe graphic card.
This patch allows drivers to use such 64-bit calling conventions.

cf41d18b72 arch/parisc: Implement fb_is_primary_device() under arch/parisc
Move PARISC's implementation of fb_is_primary_device() into the
architecture directory. This the place of the declaration and
where other architectures implement this function. No functional
changes.

7470849745 video: Move HP PARISC STI core code to shared location
STI core files have been located in console and fbdev code. Move
the source code and header to the directories for video helpers.
Also update the config and build rules such that the code depends
on the config symbol CONFIG_STI_CORE, which STI console and STI
framebuffer select automatically.

Cleans up the console makefile and prepares PARISC to implement
fb_is_primary_device() within the arch/ directory. No functional
changes.
