Kernel panic - not syncing: Fatal exception

---[ end Kernel panic - not syncing: Fatal exception
The problem is in the following lines:
new = page - pvmw.page->index +
linear_page_index(vma, pvmw.address);
The 'new' is calculated with 'page' which is given by the caller as a
destination page and some offset adjustment for thp. But this doesn't
properly work for ksm pages because pvmw.page->index doesn't change for
each address but linear_page_index() changes, which means that 'new'
points to different pages for each addresses backed by the ksm page. As
a result, we try to set totally unrelated pages as destination pages,
and that causes kernel crash.
This patch fixes the miscalculation and makes ksm page migration work
fine.

Most of the display servers today use a single surface to represent the
entire desktop even if it's stretched across multiple screens.
For vmwgfx with STDU, the maximum surface size is limited to the
maximum texture size on the host. On a 2D VM, this limits our
ability to support configurations with more than one 4K monitor.
To get past this limitation, we will now allow using a large DMA buf
as the framebuffer, and take care of blitting contents from this DMA buf
to the display buffer.

This reverts commit 2d8e60e8b074 ("drm/vmwgfx: Replace numeric
parameter like 0444 with macro")
The commit belongs to the series of 1285 patches sent to LKML on
2016-08-02, it changes the representation of file permissions from the
octal value "0600" to "S_IRUSR | S_IWUSR".
The general consensus was that the changes does not increase
readability, quite the opposite; 0600 is easier to parse mentally than
S_IRUSR | S_IWUSR.
It also causes argument inconsistency, due to commit 04319d89fbec
("drm/vmwgfx: Add an option to change assumed FB bpp") that added
another call to module_param_named() where the permissions are written
as 0600.

vmw_ldu_crtc_helper_commit() is not called if
drm_atomic_crtc_needs_modeset() decides nothing related to CRTC timing has
changed.
So a better place for this code is in vmw_ldu_primary_plane_atomic_update()

Pinning fbdev's FB at the start of VRAM prevents X from pinning
its FB. Since for ldu, the fb would be pinned anyway during a
mode set, just skip pinning it in fbdev.
This is not the best solution, but since ldu is not used much
anymore, it seems like a reasonable workaround.

We can no longer make the assumption that vmw_stdu_update_st() will

Switch over to using internal atomic API for mode set.
This removes the legacy set_config API, replacing it with
drm_atomic_helper_set_config(). The DRM helper will use various
vmwgfx-specific atomic functions to set a mode.
DRIVER_ATOMIC capability flag is not yet set, so the user mode
will still use the legacy mode set IOCTL.
v2:
* Avoid a clash between page-flip pinning and setcrtc pinning, modify
the page-flip code to use the page-flip helper and the atomic callbacks.
To enable this, we will need to add a wrapper around atomic_commit.

Atomic mode set requires us to refactor existing vmw_stdu_crtc_set_config
code into sections that check the validity of the new mode, and sections
that actually program the hardware state.
vmw_du_crtc_atomic_check() takes CRTC-related checking code. In a later
patch, vmw_du_primary_plane_atomic_check() will take framebuffer-related
checking code.
These helpers won't be called until we flip on the atomic support

v2:
* The state->num_connector is actually the total number of potential
connectors, not just the one associated with the display unit.
The proper one to check is ->connector_mask.
* Add the check to only allow plane state to be the same as crtc state
(Thanks to mlankhorst)
* Make sure to turn on SVGA mode before using VRAM. SVGA mode is

Commit 63d63cbf5e03 "NFSv4.1: Don't recheck delegations that
have already been checked" introduced a regression where when a
client received BAD_STATEID error it would not send any TEST_STATEID
and instead go into an infinite loop of resending the IO that caused
the BAD_STATEID.

Create and Add CRTC state. We currently do not track any properties
or custom states so we can technically use the DRM helpers. Creating
this code just to make potential future additions easier.
Most of the new code will be compiled but not enabled until
plane/connector state handling code is also in place.
This is the first of a series to enable atomic mode set for vmwgfx.
The atomic enabling effort was done in collaboration with Thomas
Hellstrom and the VMware Graphics Team.

In commit d0aeaa83f0b0f7a92615bbdd6b1f96812f7dcfd2 ("serial: exar:
split out the exar code from 8250_pci") the exar driver got its own
Kconfig. However the text for the new option was never changed from
the original 8250_PCI text, and hence it appears confusing when you
get asked the same question twice:
8250/16550 PCI device support (SERIAL_8250_PCI) [Y/n/m/?] (NEW)
8250/16550 PCI device support (SERIAL_8250_EXAR) [Y/n/m] (NEW)
Adding to the confusion, is that there is no help text for this new
option to indicate it is specific to a certain family of cards.
Fix both issues at the same time, as well as the space vs. tab issues
introduced in the same commit.

If uart_flush_buffer() is called between atmel_tx_dma() and
atmel_complete_tx_dma(), the circular buffer has been cleared, but not
atmel_port->tx_len.
That leads to a circular buffer overflow (dumping (UART_XMIT_SIZE -
atmel_port->tx_len) bytes).

The reference manual for the i.MX28 recommends to calculate the divisor
as
divisor = (UARTCLK * 32) / baud rate, rounded to the nearest integer
, so let's do this. For a typical setup of UARTCLK = 24 MHz and baud
rate = 115200 this changes the divisor from 6666 to 6667 and so the
actual baud rate improves from 115211.521 Bd (error ≅ 0.01 %) to
115194.240 Bd (error ≅ 0.005 %).

git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into irq/urgent
Pull irqchip fixes from Marc Zyngier
- Fix mvebu-odmi dependency selection
- Fix mips-gic virtual/hw mapping
|

Commit 4cfffcfa5106 ("irqchip/mips-gic: Fix local interrupts") added
mapping of several local interrupts during initialisation of the gic
driver. This associates virq numbers with these interrupts.
Unfortunately, as not all of the interrupts are mapped in hardware
order, when drivers subsequently request these interrupts they conflict
with the mappings that have already been set up. For example, this
manifests itself in the gic clocksource driver, which fails to probe
with the message:
clocksource: GIC: mask: 0xffffffffffffffff max_cycles: 0x7350c9738,
max_idle_ns: 440795203769 ns
GIC timer IRQ 25 setup failed: -22
This is because virq 25 (the correct IRQ number specified via device
tree) was allocated to the PERFCTR interrupt (and 24 to the timer, 26 to
the FDC). To fix this, map all of these local interrupts in the hardware
order so as to associate their virq numbers with the correct hw
interrupts.

On this Dell AIO machine, the lineout jack does not work.
We found the pin 0x1a is assigned to lineout on this machine, and in
the past, we applied ALC298_FIXUP_DELL1_MIC_NO_PRESENCE to fix the
heaset-set mic problem for this machine, this fixup will redefine
the pin 0x1a to headphone-mic, as a result the lineout doesn't
work anymore.
After consulting with Dell, they told us this machine doesn't support
microphone via headset jack, so we add a new fixup which only defines
the pin 0x18 as the headset-mic.
[rearranged the fixup insertion position by tiwai in order to make the
merge with other branches easier -- tiwai]

MCA bank 3 is reserved on systems pre-Fam17h, so it didn't have a name.
However, MCA bank 3 is defined on Fam17h systems and can be accessed
using legacy MSRs. Without a name we get a stack trace on Fam17h systems
when trying to register sysfs files for bank 3 on kernels that don't
recognize Scalable MCA.
Call MCA bank 3 "decode_unit" since this is what it represents on
Fam17h. This will allow kernels without SMCA support to see this bank on
Fam17h+ and prevent the stack trace. This will not affect older systems
since this bank is reserved on them, i.e. it'll be ignored.
Tested on AMD Fam15h and Fam17h systems.
