lru_add_drain_all() is not required by mlock() and it will drain
everything that has been cached at the time mlock is called. And
that is not really related to the memory which will be faulted in
(and cached) and mlocked by the syscall itself.
Without lru_add_drain_all() the mlocked pages can rema

Convert slram to use memremap() to map the memory it uses to back an MTD
device, as this is the proper interface for mapping memory. This change
enables normal memory to be used to back an MTD device on arm64, as arm64

The routine hugetlbfs_error_remove_page() incorrectly calls
hugetlb_fix_reserve_counts which will result in bad (negative)
reserved huge page counts. The following patch addresses this
issue.

Calling madvise(MADV_HWPOISON) on a hugetlbfs page will result in
bad (negative) reserved huge page counts. This may not happen
immediately, but may happen later when the underlying file is

Individual CPUs may have special requirements to not enter

Checking whether IRQs are enabled or disabled is a very common sanity
check, however not free of overhead especially on fastpath where such
assertion is very common.
Lockdep is a good host for such concurrency correctness check and it
even already tracks down IRQs disablement state. Just reuse its

Checking whether IRQs are disabled or enabled is often an important
sanity check. Now we can be sometimes reluctant to have it on fastpath
because reading the flags can be somewhat costly.
As suggested by Peter Zijlstra some time ago, this would be a nice
lockdep extension: it's the natural concur

Lockdep now has an integrated IRQs disabled/enabled sanity check. Just
use it instead of the ad-hoc RCU version.

The current ordering of code in device_del() triggers a WARN_ON()
in device_links_purge(), because of an unexpected link status.
The device_links_unbind_consumers() call in device_release_driver()
has to take place before device_links_purge() for the status of all
links to be correct, so move the
