In various places in the kernel, we modify the fwnode "flags" member
by doing either:
fwnode->flags |= SOME_FLAG;
fwnode->flags &= ~SOME_FLAG;
This type of modification is not thread-safe. If two threads are both
mucking with the flags at the same time then one can clobber the
other.
While flags are often modified while under the "fwnode_link_lock",
this is not universally true.
Create some accessor functions for setting, clearing, and testing the
FWNODE flags and move all users to these accessor functions. New
accessor functions use set_bit() and clear_bit(), which are
thread-safe.

The current global search for nodes in reserved_mem_matches can find nodes outside "/reserved-memory". These nodes might not have actual memory reserved (via memblock), leading to drivers (e.g., ramoops) accessing unreserved memory and causing memory corruption. Restrict the scan to the "/reserved-memory" node to ensure created devices are correctly backed by reserved memory. This enforces specification compliance and avoids dangerous probing.

This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate
conversion.

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook <kees@kernel.org>

Calling of_platform_populate() without a match table will only populate
the immediate child nodes under /firmware. This is usually fine, but in
the case of something like a "simple-mfd" node such as
"raspberrypi,bcm2835-firmware", those child nodes will not be populated.
And subsequent calls won't work either because the /firmware node is
marked as processed already.
Switch the call to of_platform_default_populate() to solve this problem.
It should be a nop for existing cases.
