few missing commits for 5.10-stable

Hi Greg,

These were missing in 5.10-stable and 5.11-stable.

dc22c1c058b5 ("nvme-pci: mark Kingston SKC2000 as not supporting the deepest power state") - Not marked for stable but looks like it should be there.

778e45d7720d ("parisc: Enable -mlong-calls gcc option with CONFIG_COMPILE_TEST")

e9c6deee00e9 ("arm64: Make CPU_BIG_ENDIAN depend on ld.bfd or ld.lld 13.0.0+") - Not marked for stable, but 5.10-stable and 5.11-stable should have the same problem.

80e9baed722c ("btrfs: export and rename qgroup_reserve_meta") - only needed for the next patch.

4d14c5cde5c2 ("btrfs: don't flush from btrfs_delayed_inode_reserve_metadata")
