Merge tag 'execve-v6.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux
Pull execve updates from Kees Cook:
- Support non-BSS ELF segments with zero filesz
Eric Biederman and I refactored ELF segment loading to handle the
case where a segment has a smaller filesz than memsz. Traditionally
linkers only did this for .bss and it was always the last segment. As
a result, the kernel only handled this case when it was the last
segment. We've had two recent cases where linkers were trying to use
these kinds of segments for other reasons, and the were in the middle
of the segment list. There was no good reason for the kernel not to
support this, and the refactor actually ends up making things more
readable too.
- Enable namespaced binfmt_misc
Christian Brauner has made it possible to use binfmt_misc with mount
namespaces. This means some traditionally root-only interfaces (for
adding/removing formats) are now more exposed (but believed to be
safe).
- Remove struct tag 'dynamic' from ELF UAPI
Alejandro Colomar noticed that the ELF UAPI has been polluting the
struct namespace with an unused and overly generic tag named
"dynamic" for no discernible reason for many many years. After
double-checking various distro source repositories, it has been
removed.

This commit adds the initial code needed to boot the GSP-RM firmware
provided by NVIDIA, bringing with it the beginnings of Ada support.
Until it's had more testing and time to bake, support is disabled by
default (except on Ada). GSP-RM usage can be enabled by passing the
"config=NvGspRm=1" module option.
