In the case where v4l2_event_dequeue fails the structure ev is not
being filled and this garbage data from the stack is being copied
to the ev32 structure and being copied back to userspace on the
VIDIOC_DQEVENT_TIME32 ioctl. Fix this by ensuring the ev structure
is zero'd to ensure uninitialized data is not leaked back.

Despite using M2M in both the decoder and encoder, this driver used
vb2_v4l2_buffer as its base buffer structure, and placed a list_head
right after the buffer declaration in order to match the layout of a
v4l2_m2m_buffer. This is very dangerous as it means the driver will
break should the layout of v4l2_m2m_buffer change.
Fix this by directly using v4l2_m2m_buffer and updating the sites that
accessed the buffer accordingly.

In vpfe_register_ccdc_device(), failure to allocate dev->hw_ops

It seems that for some HEVC videos at least one bitstream parsing
trigger must be called in order to be decoded correctly. There is no
explanation why this helps, but it was observed that several videos
with this fix are now decoded correctly and there is no regression with
others.
Without this fix, those same videos totally crash HEVC decoder (other
decoder engines are unaffected). After decoding those problematic
videos, HEVC decoder always returns only green image (all zeros).
Only complete HW reset helps.
This fix is similar to that for H264.

bdisp_device_run()
The driver may sleep while holding a spinlock.
The function call path (from bottom to top) in Linux 4.19 is:
drivers/media/platform/sti/bdisp/bdisp-hw.c, 385:
msleep in bdisp_hw_reset
drivers/media/platform/sti/bdisp/bdisp-v4l2.c, 341:
bdisp_hw_reset in bdisp_device_run
drivers/media/platform/sti/bdisp/bdisp-v4l2.c, 317:
_raw_spin_lock_irqsave in bdisp_device_run
To fix this bug, msleep() is replaced with udelay().
This bug is found by a static analysis tool STCheck written by myself.

boundary->width and boundary->height are sizes relative to
boundary->left and boundary->top coordinates, but they were not being
taken into consideration to adjust r->left and r->top, leading to the
following error:
Consider the follow as initial values for boundary and r:
struct v4l2_rect boundary = {
.left = 100,
.top = 100,
.width = 800,
.height = 600,
}
struct v4l2_rect r = {
.left = 0,
.top = 0,
.width = 1920,
.height = 960,
}
calling v4l2_rect_map_inside(&r, &boundary) was modifying r to:
r = {
.left = 0,
.top = 0,
.width = 800,
.height = 600,
}
Which is wrongly outside the boundary rectangle, because:
v4l2_rect_set_max_size(r, boundary); // r->width = 800, r->height = 600
...
if (r->left + r->width > boundary->width) // true
r->left = boundary->width - r->width; // r->left = 800 - 800
if (r->top + r->height > boundary->height) // true
r->top = boundary->height - r->height; // r->height = 600 - 600
Fix this by considering top/left coordinates from boundary.

There were several reports of building failures due to IOVA being selected
inconsistently by different drivers. All drivers that are using IOVA API
should select it unconditionally in order to avoid the compilation

The IR device on Hi3796CV300 SoC is mostly same as hix5hd2, except the
following two things.
- IR_CLK offset is 0x60 instead of 0x48.
- It needs to set an extra bit in IR_ENABLE register to enable IR.
The following changes are made to deal with them.
- Define a SoC specific data to accommodate IR_CLK offset and the flag
telling requirement of extra enable bit.
- Create function hix5hd2_ir_enable() to handle IR enabling. The original
hix5hd2_ir_enable() is all about managing IR clock, so gets renamed
to hix5hd2_ir_clk_enable().
- Device table hix5hd2_ir_table[] gets moved forward, as it's being
used by hix5hd2_ir_probe() now.

Pull RISC-V fixes from Paul Walmsley:
"Several fixes for RISC-V:
- Fix function graph trace support
- Prefix the CSR IRQ_* macro names with "RV_", to avoid collisions
with macros elsewhere in the Linux kernel tree named "IRQ_TIMER"
- Use __pa_symbol() when computing the physical address of a kernel
symbol, rather than __pa()
- Mark the RISC-V port as supporting GCOV
One DT addition:
- Describe the L2 cache controller in the FU540 DT file
One documentation update:
- Add patch acceptance guideline documentation"

Formalize, in kernel documentation, the patch acceptance policy for
arch/riscv. In summary, it states that as maintainers, we plan to
only accept patches for new modules or extensions that have been
frozen or ratified by the RISC-V Foundation.
We've been following these guidelines for the past few months. In the
meantime, we've received quite a bit of feedback that it would be
helpful to have these guidelines formally documented.
Based on a suggestion from Matthew Wilcox, we also add a link to this
file to Documentation/process/index.rst, to make this document easier
to find. The format of this document has also been changed to align
to the format outlined in the maintainer entry profiles, in accordance
with comments from Jon Corbet and Dan Williams.

"IRQ_TIMER", used in the arch/riscv CSR header file, is a sufficiently
generic macro name that it's used by several source files across the
Linux code base. Some of these other files ultimately include the
arch/riscv CSR include file, causing collisions. Fix by prefixing the
RISC-V csr.h IRQ_ macro names with an RV_ prefix.

When enabling ftrace graph tracer, it gets the tracing clock in
ftrace_push_return_trace(). Eventually, it invokes riscv_sched_clock()
to get the clock value. If riscv_sched_clock() isn't marked with
'notrace', it will call ftrace_push_return_trace() and cause infinite
loop.
The result of failure as follow:

aa_xattrs_match() is unfortunately calling vfs_getxattr_alloc() from a
context protected by an rcu_read_lock. This can not be done as
vfs_getxattr_alloc() may sleep regardles of the gfp_t value being
passed to it.
Fix this by breaking the rcu_read_lock on the policy search when the
xattr match feature is requested and restarting the search if a policy
changes occur.
Fixes: 8e51f9087f40 ("apparmor: Add support for attaching profiles via xattr, presence and value")
