The of_match_ptr(foo) macro evaluates to foo, only if
CONFIG_OF is set, otherwise to NULL. Same does ACPI_PTR with
CONFIG_ACPI. That's very helpful for drivers that can be used
with or without oftree / acpi.

With this change, calling iio_device_attach_buffer() will actually attach
more buffers.
Right now this doesn't do any validation of whether a buffer is attached
twice; maybe that can be added later (if needed). Attaching a buffer more
than once should yield noticeably bad results.

Hi,
This is an implementation of "secret" mappings backed by a file descriptor.
The file descriptor backing secret memory mappings is created using a
dedicated memfd_secret system call The desired protection mode for the
memory is configured using flags parameter of the syst

Fix non-zero phase_adj is lost after snap. Use ktime_sub

The underlying implementations of set_direct_map_invalid_noflush() and
set_direct_map_default_noflush() allow updating multiple contiguous pages
at once.
Add numpages parameter to set_direct_map_*_noflush() to expose this ability
with these APIs.

It is unsafe to allow saving of secretmem areas to the hibernation snapshot
as they would be visible after the resume and this essentially will defeat
the purpose of secret memory mappings.
Prevent hibernation whenever there are active secret memory users.

The test verifies that file descriptor created with memfd_secret does
not allow read/write operations, that secret memory mappings respect
RLIMIT_MEMLOCK and that remote accesses with process_vm_read() and
ptrace() to the secret memory fail.

I think this is a false positive due to the cycling through different
bd_mutex instances. I think my next big series aimed at 5.11 will
fix this as a side effect, so I plan to ignore this for now, but will
test the reproducer with the follow on work applied eventually.

timens_on_fork() always return 0, and maybe not

So make timens_on_fork() return nothing and do not

The definition of PMD_PAGE_ORDER denoting the number of base pages in the

Several architectures already have definition of PMD_ORDER as the size of

Removing a PAGE_SIZE page from the direct map every time such page is
allocated for a secret memory mapping will cause severe fragmentation of
the direct map. This fragmentation can be reduced by using PMD-size pages
as a pool for small pages for secret memory mappings.
