This reverts commit 3751cbda8f223549d7ea28803cbec8ac87e43ed2.
Originally the patch was created to fix the reserved-memory DT-node
parsing failure on the early stages of the platform memory initialization.
That happened due to the two early memory allocators utilization that
time: bootmem and memblock. At first the platform-specific memory mapping
array was initialized. Then the early_init_fdt_scan_reserved_mem() was
called, which couldn't fully parse the "reserved-memory" DT-node since
neither memblock nor bootmem allocators hadn't been initialized at that
stage, so the fdt_init_reserved_mem() method failed on the memory
allocation calls. Only after that the platform-specific memory mapping
were used to create proper bootmem and memblock structures and let the
early memory allocations work. That's why we had to call the
fdt_init_reserved_mem() method one more time to retry the initialization
of the features like CMA.
The necessity to have that fix was disappeared after the full memblock
support had been added to the MIPS kernel and all plat_mem_setup() had
been fixed to add the memory regions right into the memblock memory pool.
Let's revert that patch then especially after having Paul reported that
the second fdt_init_reserved_mem() call causes the reserved memory pool
being created twice bigger than implied.

The to_usb_serial_port() macro is implemented using container_of() so
there's no need to check for NULL.
Note that neither bus match() or probe() is ever called with a NULL
struct device pointer so the checks weren't just misplaced.

All usb_serial drivers return 0 in their remove callbacks and driver
core ignores the value returned by usb_serial_device_remove(). So change
the remove callback to return void and return 0 unconditionally in
usb_serial_device_remove().

In a bus remove function the passed device is always valid, so there is
no need to check for it being NULL.
(Side note: The check for port being non-NULL is broken anyhow, because
to_usb_serial_port() is a wrapper around container_of() for a member that is
not the first one. So port can hardly become NULL.)

Use kvm_pfn_t, a.k.a. u64, for the local 'pfn' variable when retrieving
a so called "remapped" hva/pfn pair. In theory, the hva could resolve to
a pfn in high memory on a 32-bit kernel.
This bug was inadvertantly exposed by commit bd2fae8da794 ("KVM: do not
assume PTE is writable after follow_pfn"), which added an error PFN value
to the mix, causing gcc to comlain about overflowing the unsigned long.
arch/x86/kvm/../../../virt/kvm/kvm_main.c: In function ‘hva_to_pfn_remapped’:

Currently, the follow_pfn function is exported for modules but
follow_pte is not. However, follow_pfn is very easy to misuse,
because it does not provide protections (so most of its callers
assume the page is writable!) and because it returns after having
already unlocked the page table lock.
Provide instead a simplified version of follow_pte that does
not have the pmdpp and range arguments. The older version
survives as follow_invalidate_pte() for use by fs/dax.c.

The usage of in_interrupt() in drivers is phased out for various
reasons.
In both exported functions where BUG_ON(in_interrupt()) is invoked,
there is a mutex_lock() afterwards. mutex_lock() contains a
might_sleep() which will already trigger a stack trace if the target
functions is called from atomic context.
Remove the BUG_ON() and add a "Context: " in the kernel-doc instead.

Add support for CQM RSSI measurement reporting and advertise the
NL80211_EXT_FEATURE_CQM_RSSI_LIST feature. This enables a userspace
supplicant such as iwd to be notified of changes in the RSSI for roaming
and signal monitoring purposes.

FW reports Tx/Rx extended MCS 12.1 to driver as "26". Driver will
convert this into base MCS 7 + EXTENDED_SC_DMG flag so kernel can do
the correct phy rate conversion. Also add log prints to print "12.1"
instead of "26" for extended MCS.

Add new level ATH10K_DBG_STA debug_mask for printing
sta related logs. This will be useful to check the
debug logs of connection and changes related to
station.

Multiple structures in the carl9170 driver have alignment
impossible alignment constraints that gcc warns about when
building with 'make W=1':
drivers/net/wireless/ath/carl9170/fwcmd.h:243:2: warning: alignment 1 of 'union <anonymous>' is less than 4 [-Wpacked-not-aligned]
drivers/net/wireless/ath/carl9170/wlan.h:373:1: warning: alignment 1 of 'struct ar9170_rx_frame_single' is less than 2 [-Wpacked-not-aligned]
In the carl9170_cmd structure, multiple members that have an explicit
alignment requirement of four bytes are added into a union with explicit
byte alignment, but this in turn is part of a structure that also has
four-byte alignment.
In the wlan.h header, multiple structures contain a ieee80211_hdr member
that is required to be two-byte aligned to avoid alignmnet faults when
processing network headers, but all members are forced to be byte-aligned
using the __packed tag at the end of the struct definition.
In both cases, leaving out the packing does not change the internal
layout of the structure but changes the alignment constraint of the
structure itself.
Change all affected structures to only apply packing where it does
not violate the alignment requirement of the contained structure.

Tx descriptor search index field should be updated with hw peer id
and not by AST Hash as per the HW/FW recommendation. Incorrect search
index causes throughput degradation in all scenario for all the
platforms. so updated the search index field with hw peer id, which
is a common change applicable for all the platforms. Also no need of these
configuration for non station type. seen 10% throughput increase in WDS
traffic with this change.

Jiri Olsa says:
====================
hi,
resolve_btfids tool is used during the kernel build,
so we should clean it on kernel's make clean.
v2 changes:
- add Song's acks on patches 1 and 4 (others changed) [Song]
- add missing / [Andrii]
- change srctree variable initialization [Andrii]
- shifted ifdef for clean target [Andrii]
thanks,
jirka
