81cf4d7d23 vt: add VT_GETCONSIZECSRPOS to retrieve console size and cursor position
The console dimension and cursor position are available through the
/dev/vcsa interface already. However the /dev/vcsa header format uses
single-byte fields therefore those values are clamped to 255.

As surprizing as this may seem, some people do use 240-column 67-row
screens (a 1920x1080 monitor with 8x16 pixel fonts) which is getting
close to the limit. Monitors with higher resolution are not uncommon
these days (3840x2160 producing a 480x135 character display) and it is
just a matter of time before someone with, say, a braille display using
the Linux VT console and BRLTTY on such a screen reports a bug about
missing and oddly misaligned screen content.

Let's add VT_GETCONSIZECSRPOS for the retrieval of console size and cursor
position without byte-sized limitations. The actual console size limit as
encoded in vt.c is 32767x32767 so using a short here is appropriate. Then
this can be used to get the cursor position when /dev/vcsa reports 255.

The screen dimension may already be obtained using TIOCGWINSZ and adding
the same information to VT_GETCONSIZECSRPOS might be redundant. However
applications that care about cursor position also care about display
size and having 2 separate system calls to obtain them separately is
wasteful. Also, the cursor position can be queried by writing "\e[6n" to
a tty and reading back the result but that may be done only by the actual
application using that tty and not a sideline observer.

80fa7a0337 vt: bracketed paste support
This is comprised of 3 aspects:

- Take note of when applications advertise bracketed paste support via
  "\e[?2004h" and "\e[?2004l".

- Insert bracketed paste markers ("\e[200~" and "\e[201~") around pasted
  content in paste_selection() when bracketed paste is active.

- Add TIOCL_GETBRACKETEDPASTE to return bracketed paste status so user
  space daemons implementing cut-and-paste functionality (e.g. gpm,
  BRLTTY) may know when to insert bracketed paste markers.

c4c7ead7b8 vt: remove VT_RESIZE and VT_RESIZEX from vt_compat_ioctl()
They are listed amon those cmd values that "treat 'arg' as an integer"
which is wrong. They should instead fall into the default case. Probably
nobody ever relied on that code since 2009 but still.

6802f3591f vt: make use of ucs_get_fallback() when glyph is unavailable
Attempt to display a fallback character when given character doesn't
have an available glyph. The substitution may not be as good as the
original character but still way more helpful than a squared question
mark.

Example substitutions: À -> A, ç -> c, ø -> o, ─ -> -, © -> C, etc.

See gen_ucs_fallback_table.py for a comprehensive list.

c40b91e38e 8250: microchip: pci1xxxx: Add PCIe Hot reset disable support for Rev C0 and later devices
Systems that issue PCIe hot reset requests during a suspend/resume
cycle cause PCI1XXXX device revisions prior to C0 to get its UART
configuration registers reset to hardware default values. This results
in device inaccessibility and data transfer failures. Starting with
Revision C0, support was added in the device hardware (via the Hot
Reset Disable Bit) to allow resetting only the PCIe interface and its
associated logic, but preserving the UART configuration during a hot
reset. This patch enables the hot reset disable feature during suspend/
resume for C0 and later revisions of the device.

Pull PCI fixes from Bjorn Helgaas:

 - When releasing a start-aligned resource, e.g., a bridge window, save
   start/end/flags for the next assignment attempt; fixes a v6.15-rc1
   regression (Ilpo Järvinen)

 - Move set_pcie_speed.sh from TEST_PROGS to TEST_FILE; fixes a bwctrl
   selftest v6.15-rc1 regression (Ilpo Järvinen)

 - Add Manivannan Sadhasivam as maintainer of native host bridge and
   endpoint drivers (Manivannan Sadhasivam)

 - In endpoint test driver, defer IRQ allocation from .probe() until
   ioctl() to fix a regression on platforms where the Vendor/Device ID
   match doesn't include driver_data (Niklas Cassel)

    this also translated to some cleanups to OpenRISC cache flush and

Pull drm fixes from Dave Airlie:
 "Weekly drm fixes, mostly amdgpu, with some exynos cleanups and a
  couple of minor fixes, seems a bit quiet, but probably some lag from
  Easter holidays.

  amdgpu:
   - P2P DMA fixes
   - Display reset fixes
   - DCN 3.5 fixes
   - ACPI EDID fix
   - LTTPR fix
   - mode_valid() fix

  exynos:
   - fix spelling error
   - remove redundant error handling in exynos_drm_vidi.c module
   - marks struct decon_data as const in the exynos7_drm_decon driver
     since it is only read
   - Remove unnecessary checking in exynos_drm_drv.c module

  meson:
   - Fix VCLK calculation

  panel:
   - jd9365a: Fix reset polarity"

c2d2c5c0d6 vt: move UCS tables to the "shipped" form
Use the "shipped" mechanism to copy pre-generated tables to the build
tree by default. If GENERATE_UCS_TABLES=1 then they are generated at
build time instead. If GENERATE_UCS_TABLES=2 then
gen_ucs_recompose_table.py is invoked with --full.

d8f81c82b1 vt: refresh ucs_width_table.h and adjust code in ucs.c accordingly
Width tables are now split into BMP (16-bit) and non-BMP (above 16-bit).
This reduces the corresponding text size by 20-25%.

Note: scripts/checkpatch.pl complains about "... exceeds 100 columns".
      Please ignore.

5617aeb14a vt: pad double-width code points with a zero-width space
In the Unicode screen buffer, we follow double-width code points with a
space to maintain proper column alignment. This, however, creates
semantic problems when e.g. using cut and paste.

Let's use a better code point for the column padding's purpose i.e. a
zero-width space rather than a full space. This way the combination
retains a width of 2.

b5c574995d vt: support Unicode recomposition
Try replacing any decomposed Unicode sequence by the corresponding
recomposed code point. Code point to glyph correspondance works best
after recomposition, and this apply mostly to single-width code points
therefore we can't preserve them in their decomposed form anyway.

03c6de017b vt: introduce gen_ucs_recompose_table.py to create ucs_recompose_table.h
The generated table maps base character + combining mark pairs to their
precomposed equivalents using Python's unicodedata module.

The default script behavior is to create a table with most commonly used
Latin, Greek, and Cyrillic recomposition pairs only. It is much smaller
than the table with all possible recomposition pairs (71 entries vs 1000
entries). But if one needs/wants the full table then simply running the
script with the --full argument will generate it.
