The hook android_vh_ra_tuning_max_page is not used by any vendor, so
remove it to help with merge issues with future LTS releases.
If this is needed by any real user, it can easily be reverted to add it
back and then the symbol should be added to the abi list at the same

This 'commit 86588296acbf ("fdt: Properly handle "no-map" field in the
memory region")' is keeping the no-map regions in memblock.memory with
MEMBLOCK_NOMAP flag set to use no-map memory for EFI using memblock
api's, but during the initialization sparse_init mark all memblock.memory
as present using for_each_mem_pfn_range, which is creating the memmap for
no-map memblock regions.
Upstream has suggested to make use of bootloader to pass this as not a
memory,but because of possibility that some bootloaders might not support
this and also due to time constraints in evaluating this approach on 5.10,
Use command line parameter as a temporary solution. Get in the appropriate
solution later after further discussion with upstream.
Add kernel param "android12_only.will_be_removed_soon.memblock_nomap_remove"
which when enabled will remove page structs for these regions using memblock_remove.
With this change we will be able to save ~11MB memory for ~612MB carve out.

cgroup_update_dfl_csses() write-lock the threadgroup_rwsem as updating the
csses can trigger process migrations. However, if the subtree doesn't
contain any tasks, there aren't gonna be any cgroup migrations. This
condition can be trivially detected by testing whether
mgctx.preloaded_src_csets is empty. Elide write-locking threadgroup_rwsem if
the subtree is empty.
After this optimization, the usage pattern of creating a cgroup, enabling
the necessary controllers, and then seeding it with CLONE_INTO_CGROUP and
then removing the cgroup after it becomes empty doesn't need to write-lock
threadgroup_rwsem at all.
