The function pointer declaration for the cpu_addr_fixup() callback uses
"cpu_addr" as parameter name.
Likewise, the argument that is supplied to the function pointer when the
function is actually called is "cpu_addr".
Rename the artpec6_pcie_cpu_addr_fixup() parameter name to match
reality.

pbus_size_mem() keeps the size of the optional resources in
children_add_size. When calculating the PCI bridge window size,
calculate_memsize() lower bounds size by old_size before adding
children_add_size and performing the window size alignment. This
results in double counting for the resources in children_add_size
because old_size may be based on the previous size of the bridge
window after it has already included children_add_size (that is,
size1 in pbus_size_mem() from an earlier invocation of that
function).
As a result, on repeated remove of the bus & rescan cycles the resource
size keeps increasing when children_add_size is non-zero as can be seen
from this extract:
iomem0: 23fffd00000-23fffdfffff : PCI Bus 0000:03 # 1MiB
iomem1: 20000000000-200001fffff : PCI Bus 0000:03 # 2MiB
iomem2: 20000000000-200002fffff : PCI Bus 0000:03 # 3MiB
iomem3: 20000000000-200003fffff : PCI Bus 0000:03 # 4MiB
iomem4: 20000000000-200004fffff : PCI Bus 0000:03 # 5MiB
Solve the double counting by moving old_size check later in
calculate_memsize() so that children_add_size is already accounted for.
After the patch, the bridge window retains its size as expected:
iomem0: 23fffd00000-23fffdfffff : PCI Bus 0000:03 # 1MiB
iomem1: 20000000000-200000fffff : PCI Bus 0000:03 # 1MiB

allocate_resource() accepts ->alignf() callback to perform custom alignment
beyond constraint->align. If alignf is NULL, simple_align_resource() is
used which only returns avail->start (no change).
Using avail->start directly is natural and can be done with a conditional
in __find_resource_space() instead which avoids unnecessarily using
callback. It makes the code inside __find_resource_space() more obvious and
removes the need for the caller to provide constraint->alignf
unnecessarily.
This is preparation for exporting find_resource_space().

TME (Total Memory Encryption) and MKTME (Multi-Key Total Memory
Encryption) BIOS detection were introduced together here [1] and
are loosely coupled in the Intel CPU init code.
TME is a hardware only feature and its BIOS status is all that needs
to be shared with the kernel user: enabled or disabled. The TME
algorithm the BIOS is using and whether or not the kernel recognizes
that algorithm is useless to the kernel user.
MKTME is a hardware feature that requires kernel support. MKTME
detection code was added in advance of broader kernel support for
MKTME that never followed. So, rather than continuing to spew
needless and confusing messages about BIOS MKTME status, remove
most of the MKTME pieces from detect_tme_early().
Keep one useful message: alert the user when BIOS enabled MKTME
reduces the available physical address bits. Recovery of the MKTME
consumed bits requires a reboot with MKTME disabled in BIOS.
There is no functional change for the user, only a change in boot
messages. Below is one example when both TME and MKTME are enabled
in BIOS with AES_XTS_256 which is unknown to the detect tme code.
Before:
[] x86/tme: enabled by BIOS
[] x86/tme: Unknown policy is active: 0x2
[] x86/mktme: No known encryption algorithm is supported: 0x4
[] x86/mktme: enabled by BIOS
[] x86/mktme: 127 KeyIDs available
After:
[] x86/tme: enabled by BIOS
[] x86/mktme: BIOS enable: x86_phys_bits reduced by 8

By default the BT WAKE signal inside the M.2 key E connector on Radxa
Rock 5B is driven low, which results in the Bluetooth function being
disabled even if the inserted M.2 card supports it. Expose this signal
as an RFKILL device so that it can be enabled by the userspace.
Tested with an Intel AX210 card, which connects a Bluetooth device over
the USB 2.0 bus.

During engine LRC initialization a number of registers need to be
programmed as general setup. This programming is not a "workaround" so
naming the RTP table as "lrc_was" is misleading; switch to the name
"lrc_setup" to more accurately describe what the table is actually for.

Function handle_callback() is used to request a glock demote. This
often happens in response to a conflicting remote locking request and
subsequent bast callback from DLM, but there are other reasons for
triggering a demote request as well, such as when trying to release a
glock in response to memory pressure. To clarify that, rename the
function to request_demote().

The GLF_FROZEN flag indicates that a reply to a DLM locking request has
been received, but should not be processed at this time. To clarify
that meaning, rename the flag to GLF_HAVE_FROZEN_REPLY.

The GLF_REPLY_PENDING flag indicates to glock_work_func() that in
response to a locking request, DLM has sent a reply that needs to be
processed. A flag with that name could as well indicate that we are
waiting on a reply from DLM, however. To disambiguate these two cases,
rename the flag to GLF_HAVE_REPLY.

Rename the GLF_FREEING flag to GLF_UNLOCKED, and the ->go_free glock
operation to ->go_unlocked. This mechanism is used to wait for the
underlying DLM lock to be unlocked; being able to free the glock is a
consequence of the DLM lock being unlocked.

Function __gfs2_glock_dq() gets defined before it is used, so there is
no need for a separate function declaration.

SA8775P SoC supports Hyper DMA (HDMA) DMA Engine present in the DWC IP. So,
enable it in the EPF driver so that the DMA Engine APIs can be used for data
transfer.
