If a CPU doesn't support the page size for which the kernel is
configured, then we will complain and refuse to bring it online. For
secondary CPUs (and the boot CPU on a system booting with EFI), we will
also print an error identifying the mismatch.
Consequently, the only time that the cpufeature code can detect a
granule size mismatch is for a granule other than the one that is
currently being used. Although we would rather such systems didn't
exist, we've unfortunately lost that battle and Kevin reports that
on his amlogic S922X (odroid-n2 board) we end up warning and taining
with defconfig because 16k pages are not supported by all of the CPUs.
In such a situation, we don't actually care about the feature mismatch,
particularly now that KVM only exposes the sanitised view of the CPU
registers (commit 93390c0a1b - "arm64: KVM: Hide unsupported AArch64
CPU features from guests"). Treat the granule fields as non-strict and
let Kevin run without a tainted kernel.

One of the modifications made by commit d916b1be94 ("nvme-pci: use
host managed power state for suspend") was adding a pci_save_state()
call to nvme_suspend() so as to instruct the PCI bus type to leave
devices handled by the nvme driver in D0 during suspend-to-idle.
That was done with the assumption that ASPM would transition the
device's PCIe link into a low-power state when the device became
inactive. However, if ASPM is disabled for the device, its PCIe
link will stay in L0 and in that case commit d916b1be94 is likely
to cause the energy used by the system while suspended to increase.
Namely, if the device in question works in accordance with the PCIe
specification, putting it into D3hot causes its PCIe link to go to
L1 or L2/L3 Ready, which is lower-power than L0. Since the energy
used by the system while suspended depends on the state of its PCIe
link (as a general rule, the lower-power the state of the link, the
less energy the system will use), putting the device into D3hot
during suspend-to-idle should be more energy-efficient that leaving
it in D0 with disabled ASPM.
For this reason, avoid leaving NVMe devices with disabled ASPM in D0
during suspend-to-idle. Instead, shut them down entirely and let
the PCI bus type put them into D3.

"Here is a single tty kgdb fix for 5.3-rc4.
It fixes an annoying log message that has caused kdb to become
useless. It's another fallout from commit ddde3c18b7 ("vt: More
locking checks") which tries to enforce locking checks more strictly
in the tty layer, unfortunatly when kdb is stopped, there's no need
for locks :)
This patch has been linux-next for a while with no reported issues"

Here are some small USB fixes for 5.3-rc4.
The "biggest" one here is moving code from one file to another in order
to fix a long-standing race condition with the creation of sysfs files
for USB devices. Turns out that there are now userspace tools out there
that are hitting this long-known bug, so it's time to fix them.
Thankfully the tool-maker in this case fixed the issue :)
The other patches in here are all fixes for reported issues. Now that
syzbot knows how to fuzz USB drivers better, and is starting to now fuzz
the userspace facing side of them at the same time, there will be more

All the way back to introducing dma_common_mmap we've defaulted to mark
the pages as uncached. But this is wrong for DMA coherent devices.
Later on DMA_ATTR_WRITE_COMBINE also got incorrect treatment as that
flag is only treated special on the alloc side for non-coherent devices.
Introduce a new dma_pgprot helper that deals with the check for coherent
devices so that only the remapping cases ever reach arch_dma_mmap_pgprot
and we thus ensure no aliasing of page attributes happens, which makes
the powerpc version of arch_dma_mmap_pgprot obsolete and simplifies the
remaining ones.
Note that this means arch_dma_mmap_pgprot is a bit misnamed now, but
we'll phase it out soon.

To avoid reducing the frequency of a CPU prematurely, we skip reducing
the frequency if the CPU had been busy recently.
This should not be done when the limits of the policy are changed, for
example due to thermal throttling. We should always get the frequency
within the new limits as soon as possible.
Trying to fix this by using only one flag, i.e. need_freq_update, can
lead to a race condition where the flag gets cleared without forcing us
to change the frequency at least once. And so this patch introduces
another flag to avoid that race condition.
