We are now in a position where no caller of pin_user_pages() requires the
vmas parameter at all, so eliminate this parameter from the function and
all callers.
This clears the way to removing the vmas parameter from GUP altogether.

No invocation of pin_user_pages_remote() uses the vmas parameter, so
remove it. This forms part of a larger patch set eliminating the use of
the vmas parameters altogether.

Patch series "remove the vmas parameter from GUP APIs", v6.
(pin_/get)_user_pages[_remote]() each provide an optional output parameter
for an array of VMA objects associated with each page in the input range.
These provide the means for VMAs to be returned, as long as mm->mmap_lock
is never released during the GUP operation (i.e. the internal flag
FOLL_UNLOCKABLE is not specified).
In addition, these VMAs can only be accessed with the mmap_lock held and
become invalidated the moment it is released.
The vast majority of invocations do not use this functionality and of
those that do, all but one case retrieve a single VMA to perform checks
upon.
It is not egregious in the single VMA cases to simply replace the
operation with a vma_lookup(). In these cases we duplicate the (fast)
lookup on a slow path already under the mmap_lock, abstracted to a new
get_user_page_vma_remote() inline helper function which also performs
error checking and reference count maintenance.
The special case is io_uring, where io_pin_pages() specifically needs to
assert that the VMAs underlying the range do not result in broken
long-term GUP file-backed mappings.
As GUP now internally asserts that FOLL_LONGTERM mappings are not
file-backed in a broken fashion (i.e. requiring dirty tracking) - as
implemented in "mm/gup: disallow FOLL_LONGTERM GUP-nonfast writing to
file-backed mappings" - this logic is no longer required and so we can
simply remove it altogether from io_uring.
Eliminating the vmas parameter eliminates an entire class of danging
pointer errors that might have occured should the lock have been
incorrectly released.
In addition, the API is simplified and now clearly expresses what it is
intended for - applying the specified GUP flags and (if pinning) returning
pinned pages.
This change additionally opens the door to further potential improvements
in GUP and the possible marrying of disparate code paths.
I have run this series against gup_test with no issues.
Thanks to Matthew Wilcox for suggesting this refactoring!
This patch (of 6):
No invocation of get_user_pages() use the vmas parameter, so remove it.
The GUP API is confusing and caveated. Recent changes have done much to
improve that, however there is more we can do. Exporting vmas is a prime
target as the caller has to be extremely careful to preclude their use
after the mmap_lock has expired or otherwise be left with dangling
pointers.
Removing the vmas parameter focuses the GUP functions upon their primary
purpose - pinning (and outputting) pages as well as performing the actions
implied by the input flags.
This is part of a patch series aiming to remove the vmas parameter
altogether.

When media is not ready do not assume that the capacity information from
the identify command is valid, i.e. ->total_bytes
->partition_align_bytes ->{volatile,persistent}_only_bytes. Explicitly
zero out the capacity resources and exit early.
Given zero-init of those fields this patch is functionally equivalent to
the prior state, but it improves readability and robustness going
forward.

Arm FF-A fixes for v6.4
Quite a few fixes to address set of assorted issues:
1. NULL pointer dereference if the ffa driver doesn't provide remove()
callback as it is currently executed unconditionally
2. FF-A core probe failure on systems with v1.0 firmware as the new

3. Failure to register more than one logical partition or service within
the same physical partition as the device name contains only VM ID
which will be same for all but each will have unique UUID.
4. Rejection of certain memory interface transmissions by the receivers
(secure partitions) as few MBZ fields are non-zero due to lack of
explicit re-initialization of those fields

Driver should update policy->cur after updating the frequency.
Currently amd_pstate doesn't update policy->cur when `adjust_perf`
is used. Which causes /proc/cpuinfo to show wrong cpu frequency.
Fix this by updating policy->cur with correct frequency value in
adjust_perf function callback.
- Before the fix: (setting min freq to 1.5 MHz)
[root@amd]# cat /proc/cpuinfo | grep "cpu MHz" | sort | uniq --count
1 cpu MHz : 1777.016
1 cpu MHz : 1797.160
1 cpu MHz : 1797.270
189 cpu MHz : 400.000
- After the fix: (setting min freq to 1.5 MHz)
[root@amd]# cat /proc/cpuinfo | grep "cpu MHz" | sort | uniq --count
1 cpu MHz : 1753.353
1 cpu MHz : 1756.838

[Why]
During gpu-reset, we toggle vblank irq by calling dc_interrupt_set()
instead of amdgpu_irq_get/put() because we don't want to change the irq
source's refcount. However, we see the warning when vblank irq is enabled
by dc_interrupt_set() during gpu-reset but disabled by amdgpu_irq_put()
after gpu-reset.
[How]
Only in dm_gpureset_toggle_interrupts() we toggle vblank interrupts by
calling dc_interrupt_set(). Apart from this we call dm_set_vblank()
which uses amdgpu_irq_get/put() to operate vblank irq.

The existing code silently converts read operations with the
REQ_FUA bit set into write-barrier operations. This results in data
loss as the backend scribbles zeroes over the data instead of returning
it.
While the REQ_FUA bit doesn't make sense on a read operation, at least
one well-known out-of-tree kernel module does set it and since it
results in data loss, let's be safe here and only look at REQ_FUA for
writes.

The commit c6d96df9fa2c ("net: ethernet: mtk_eth_soc: drop generic vlan rx
offload, only use DSA untagging") makes VLAN RX offloading to be only used
on the SoCs without the MTK_NETSYS_V2 ability (which are not just MT7621
and MT7622). The commit disables the proper handling of special tagged
(DSA) frames, added with commit 87e3df4961f4 ("net-next: ethernet:
mediatek: add CDM able to recognize the tag for DSA"), for non
MTK_NETSYS_V2 SoCs when it finds a MAC that does not use DSA. So if the
other MAC uses DSA, the CDMQ component transmits DSA tagged frames to the
CPU improperly. This issue can be observed on frames with TCP, for example,
a TCP speed test using iperf3 won't work.
The commit disables the proper handling of special tagged (DSA) frames
because it assumes that these SoCs don't use more than one MAC, which is
wrong. Although I made Frank address this false assumption on the patch log
when they sent the patch on behalf of Felix, the code still made changes
with this assumption.
Therefore, the proper handling of special tagged (DSA) frames must be kept
enabled in all circumstances as it doesn't affect non DSA tagged frames.
Hardware DSA untagging, introduced with the commit 2d7605a72906 ("net:
ethernet: mtk_eth_soc: enable hardware DSA untagging"), and VLAN RX
offloading are operations on the two CDM components of the frame engine,
CDMP and CDMQ, which connect to Packet DMA (PDMA) and QoS DMA (QDMA) and
are between the MACs and the CPU. These operations apply to all MACs of the
SoC so if one MAC uses DSA and the other doesn't, the hardware DSA
untagging operation will cause the CDMP component to transmit non DSA
tagged frames to the CPU improperly.
Since the VLAN RX offloading feature configuration was dropped, VLAN RX
offloading can only be used along with hardware DSA untagging. So, for the
case above, we need to disable both features and leave it to the CPU,
therefore software, to untag the DSA and VLAN tags.
So the correct way to handle this is:
For all SoCs:
Enable the proper handling of special tagged (DSA) frames
(MTK_CDMQ_IG_CTRL).
For non MTK_NETSYS_V2 SoCs:
Enable hardware DSA untagging (MTK_CDMP_IG_CTRL).
Enable VLAN RX offloading (MTK_CDMP_EG_CTRL).
When a non MTK_NETSYS_V2 SoC MAC does not use DSA:
Disable hardware DSA untagging (MTK_CDMP_IG_CTRL).
Disable VLAN RX offloading (MTK_CDMP_EG_CTRL).

The driver's interrupt service routine is requested with the
IRQF_NO_THREAD if MSI is available. This means that the routine is
invoked in hardirq context even on PREEMPT_RT. The routine itself is
relatively short and schedules a worker, performs register access and
schedules NAPI. On PREEMPT_RT, scheduling NAPI from hardirq results in
waking ksoftirqd for further processing so using NAPI threads with this
driver is highly recommended since it NULL routes the threaded-IRQ
efforts.
Adding rtl_hw_aspm_clkreq_enable() to the ISR is problematic on
PREEMPT_RT because the function uses spinlock_t locks which become
sleeping locks on PREEMPT_RT. The locks are only used to protect
register access and don't nest into other functions or locks. They are
also not used for unbounded period of time. Therefore it looks okay to
convert them to raw_spinlock_t.
Convert the three locks which are used from the interrupt service
routine to raw_spinlock_t.
