Add two new helper functions to retrieve a mapping of priority to PCP
and DSCP bitmasks, where each bitmap contains ones in positions that
match a rewrite entry.
dcb_ieee_getrewr_prio_dscp_mask_map() reuses the dcb_ieee_app_prio_map,
as this struct is already used for a similar mapping in the app table.

Add new rewrite table and all the required functions, offload hooks and
bookkeeping for maintaining it. The rewrite table reuses the app struct,
and the entire set of app selectors. As such, some bookeeping code can
be shared between the rewrite- and the APP table.
New functions for getting, setting and deleting entries has been added.
Apart from operating on the rewrite list, these functions do not emit a
DCB_APP_EVENT when the list os modified. The new dcb_getrewr does a
lookup based on selector and priority and returns the protocol, so that
mappings from priority to protocol, for a given selector and ifindex is
obtained.
Also, a new nested attribute has been added, that encapsulates one or
more app structs. This attribute is used to distinguish the two tables.
The dcb_lock used for the APP table is reused for the rewrite table.

Currently we traverse all symbols of all modules to find the specified
function for the specified module. But in reality, we just need to find
the given module and then traverse all the symbols in it.
Let's add a new parameter 'const char *modname' to function
module_kallsyms_on_each_symbol(), then we can compare the module names
directly in this function and call hook 'fn' after matching. If 'modname'
is NULL, the symbols of all modules are still traversed for compatibility
with other usage cases.
Phase1: mod1-->mod2..(subsequent modules do not need to be compared)
|
Phase2: -->f1-->f2-->f3
Assuming that there are m modules, each module has n symbols on average,
then the time complexity is reduced from O(m * n) to O(m) + O(n).

KVM already has a 'GPA_INVALID' defined as (~(gpa_t)0) in kvm_types.h,
and it is used by ARM code. We do not need another definition of
'INVALID_GPA' for X86 specifically.
Instead of using the common 'GPA_INVALID' for X86, replace it with
'INVALID_GPA', and change the users of 'GPA_INVALID' so that the diff
can be smaller. Also because the name 'INVALID_GPA' tells the user we
are using an invalid GPA, while the name 'GPA_INVALID' is emphasizing
the GPA is an invalid one.

Drivers such as fbcon however do not have such limitation, so this

to use to avoid this limitation, thus opening the patch to >32 pixels

The current con_font_get/set API currently hardcodes a 32-pixel-tall
limitation, which only dates from the old VGA hardware which could not
handle taller fonts than that.
This change just adds a vpitch parameter to release this
constraint. Drivers which do not support vpitch != 32 can just return
EINVAL when it is not 32, font loading tools will revert to trying 32
and succeed.
This change makes the fbcon driver consider vpitch appropriately, thus
making it able to load large fonts.

Neither FIELD_PREP() nor *_encode_bits() can be used
in constant contexts (such as initializers), but we
don't want to define shift constants for all masks
just for use in initializers, and having checks that
the values fit is also useful.
Therefore, add FIELD_PREP_CONST() which is a smaller
version of FIELD_PREP() that can only take constant
arguments and has less friendly (but not less strict)
error checks, and expands to a constant value.

Make fwnode_graph_for_each_endpoint() consistent with the rest of
for_each_*() definitions in the file, i.e. use the form of
for (iter = func(NULL); iter; \
iter = func(iter))
as it's done in all the rest of the similar macro definitions.

Currently there is no easy way for a drm driver to safely check and allow
drm_vma_offset_node for a drm file just once. Allow drm drivers to call
non-refcounted version of drm_vma_node_allow() so that a driver doesn't
need to keep track of each drm_vma_node_allow() to call subsequent
drm_vma_node_revoke() to prevent memory leak.

There is a custom (non-USB IF) extension to the USB standard:
https://wicg.github.io/webusb/
This specification is published under the W3C Community Contributor
Agreement, which in particular allows to implement the specification
without any royalties.
The specification allows USB gadgets to announce an URL to landing
page and describes a Javascript interface for websites to interact
with the USB gadget, if the user allows it. It is currently
supported by Chromium-based browsers, such as Chrome, Edge and
Opera on all major operating systems including Linux.
This patch adds optional support for Linux-based USB gadgets
wishing to expose such a landing page.
During device enumeration, a host recognizes that the announced
USB version is at least 2.01, which means, that there are BOS
descriptors available. The device than announces WebUSB support
using a platform device capability. This includes a vendor code
under which the landing page URL can be retrieved using a
vendor-specific request.
Previously, the BOS descriptors would unconditionally include an
LPM related descriptor, as BOS descriptors were only ever sent
when the device was LPM capable. As this is no longer the case,
this patch puts this descriptor behind a lpm_capable condition.
Usage is modeled after os_desc descriptors:
echo 1 > webusb/use
echo "https://www.kernel.org" > webusb/landingPage
lsusb will report the device with the following lines:
Platform Device Capability:
bLength 24
bDescriptorType 16
bDevCapabilityType 5
bReserved 0
PlatformCapabilityUUID {3408b638-09a9-47a0-8bfd-a0768815b665}
WebUSB:
bcdVersion 1.00
bVendorCode 0

Although the quirks are internal to EDID parsing, it'll be helpful to
store them in display info to avoid having to pass them around.
This will also help separate adding probed modes (which needs the
quirks) from updating display info.

CoreSight sources provide a callback (.trace_id) in the standard source
ops which returns the ID to the core code. This was used to check that
sources all had a unique Trace ID.
Uniqueness is now gauranteed by the Trace ID allocation system, and the
check code has been removed from the core.
This patch removes the unneeded and unused .trace_id source ops
from the ops structure and implementations in etm3x, etm4x and stm.

The existing mechanism to assign Trace ID values to sources is limited
and does not scale for larger multicore / multi trace source systems.
The API introduces functions that reserve IDs based on availabilty
represented by a coresight_trace_id_map structure. This records the
used and free IDs in a bitmap.
CPU bound sources such as ETMs use the coresight_trace_id_get_cpu_id
coresight_trace_id_put_cpu_id pair of functions. The API will record
the ID associated with the CPU. This ensures that the same ID will be
re-used while perf events are active on the CPU. The put_cpu_id function
will pend release of the ID until all perf cs_etm sessions are complete.
For backward compatibility the functions will attempt to use the same
CPU IDs as the legacy system would have used if these are still available.
Non-cpu sources, such as the STM can use coresight_trace_id_get_system_id /
coresight_trace_id_put_system_id.
