Save return address, Node ID, and the Instance ID number to start.
Currently, the UMC number is used as the Instance ID, but future DF

Also include a "tmp" field to use when reading registers. This is to

The DF Indirect Access method allows for "Broadcast" accesses in which
case no specific instance is targeted. Add support using a reserved

register appropriately.
Define helpers functions for instance and broadcast reads and use them

Dan reports that Anjaneya Chagam can no longer use the efi=nosoftreserve
kernel command line parameter to suppress "soft reservation" behavior.
This is due to the fact that the following call-chain happens at boot:
early_reserve_memory
|-> efi_memblock_x86_reserve_range
|-> efi_fake_memmap_early
which does
if (!efi_soft_reserve_enabled())
return;
and that would have set EFI_MEM_NO_SOFT_RESERVE after having parsed
"nosoftreserve".
However, parse_early_param() gets called *after* it, leading to the boot
cmdline not being taken into account.
Therefore, carve out the command line preparation into a separate
function which does the early param parsing too. So that it all goes
together.
And then call that function before early_reserve_memory() so that the
params would have been parsed by then.

Currently, creating a batman-adv interface in an unprivileged LXD
container and attaching secondary interfaces to it with "ip" or "batctl"
works fine. However all batctl debug and configuration commands
fail:
root@container:~# batctl originators
Error received: Operation not permitted
root@container:~# batctl orig_interval
1000
root@container:~# batctl orig_interval 2000
root@container:~# batctl orig_interval
1000
To fix this change the generic netlink permissions from GENL_ADMIN_PERM
to GENL_UNS_ADMIN_PERM. This way a batman-adv interface is fully
maintainable as root from within a user namespace, from an unprivileged
container.
All except one batman-adv netlink setting are per interface and do not
leak information or change settings from the host system and are
therefore save to retrieve or modify as root from within an unprivileged
container.
"batctl routing_algo" / BATADV_CMD_GET_ROUTING_ALGOS is the only
exception: It provides the batman-adv kernel module wide default routing
algorithm. However it is read-only from netlink and an unprivileged
container is still not allowed to modify
/sys/module/batman_adv/parameters/routing_algo. Instead it is advised to
use the newly introduced "batctl if create routing_algo RA_NAME" /
IFLA_BATADV_ALGO_NAME to set the routing algorithm on interface
creation, which already works fine in an unprivileged container.

Change all GEM SHMEM object functions that receive a GEM object
of type struct drm_gem_object to expect an object of type
struct drm_gem_shmem_object instead.
This change reduces the number of upcasts from struct drm_gem_object
by moving them into callers. The C compiler can now verify that the
GEM SHMEM functions are called with the correct type.
For consistency, the patch also renames drm_gem_shmem_free_object to
drm_gem_shmem_free. It further updates documentation for a number of

In commit 8c89f7b3d3 ("mac80211: Use flex-array for radiotap header
bitmap") we accidentally pointed the position to the wrong place, so
we overwrite a present bitmap, and thus cause all kinds of trouble.
To see the issue, note that the previous code read:
pos = (void *)(it_present + 1);
The requirement now is that we need to calculate pos via it_optional,
to not trigger the compiler hardening checks, as:
pos = (void *)&rthdr->it_optional[...];
Rewriting the original expression, we get (obviously, since that just
adds "+ x - x" terms):
pos = (void *)(it_present + 1 + rthdr->it_optional - rthdr->it_optional)
and moving the "+ rthdr->it_optional" outside to be used as an array:
pos = (void *)&rthdr->it_optional[it_present + 1 - rthdr->it_optional];
The original is off by one, fix it.
