pci_bus_alloc_from_region() allocates MMIO space by iterating through all
the resources available on the bus. The available resource might be
reduced if the caller requires 32-bit space or we're avoiding BIOS or E820
areas.
Don't bother calling allocate_resource() if we need more space than is
available in this resource. This prevents some pointless and annoying
messages about avoided areas.

Firmware can use EfiMemoryMappedIO to request that MMIO regions be mapped
by the OS so they can be accessed by EFI runtime services, but should have
no other significance to the OS (UEFI r2.10, sec 7.2). However, most
bootloaders and EFI stubs convert EfiMemoryMappedIO regions to
E820_TYPE_RESERVED entries, which prevent Linux from allocating space from
them (see remove_e820_regions()).
Some platforms use EfiMemoryMappedIO entries for PCI MMCONFIG space and PCI
host bridge windows, which means Linux can't allocate BAR space for
hot-added devices.
Remove large EfiMemoryMappedIO regions from the E820 map to avoid this
problem.
Leave small (< 256KB) EfiMemoryMappedIO regions alone because on some
platforms, these describe non-window space that's included in host bridge
_CRS. If we assign that space to PCI devices, they don't work. On the
Lenovo X1 Carbon, this leads to suspend/resume failures.
The previous solution to the problem of allocating BARs in these regions
was to add pci_crs_quirks[] entries to disable E820 checking for these
machines (see d341838d776a ("x86/PCI: Disable E820 reserved region clipping
via quirks")):
Acer DMI_PRODUCT_NAME Spin SP513-54N
Clevo DMI_BOARD_NAME X170KM-G
Lenovo DMI_PRODUCT_VERSION *IIL*
Florent reported the BAR allocation issue on the Clevo NL4XLU. We could
add another quirk for the NL4XLU, but I hope this generic change can solve
it for many machines without having to add quirks.
This change has been tested on Clevo X170KM-G (Konrad) and Lenovo Ideapad
Slim 3 (Matt) and solves the problem even when overriding the existing
quirks by booting with "pci=use_e820".

Previously portdrv allowed the AER service for any device with an AER
capability (assuming Linux had control of AER) even though the AER service
driver only attaches to Root Port and RCECs.
Because get_port_device_capability() included AER for non-RP, non-RCEC
devices, we tried to initialize the AER IRQ even though these devices
don't generate AER interrupts.
Intel DG1 and DG2 discrete graphics cards contain a switch leading to a
GPU. The switch supports AER but not MSI, so initializing an AER IRQ
failed, and portdrv failed to claim the switch port at all. The GPU itself
could be suspended, but the switch could not be put in a low-power state
because it had no driver.
Don't allow the AER service on non-Root Port, non-Root Complex Event
Collector devices. This means we won't enable Bus Mastering if the device
doesn't require MSI, the AER service will not appear in sysfs, and the AER
service driver will not bind to the device.

When built with Control Flow Integrity, function prototypes between
caller and function declaration must match. These mismatches are visible
at compile time with the new -Wcast-function-type-strict in Clang[1].
There were 97 warnings produced by NFS. For example:
fs/nfsd/nfs4xdr.c:2228:17: warning: cast from '__be32 (*)(struct nfsd4_compoundargs *, struct nfsd4_access *)' (aka 'unsigned int (*)(struct nfsd4_compoundargs *, struct nfsd4_access *)') to 'nfsd4_dec' (aka 'unsigned int (*)(struct nfsd4_compoundargs *, void *)') converts to incompatible function type [-Wcast-function-type-strict]
[OP_ACCESS] = (nfsd4_dec)nfsd4_decode_access,
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The enc/dec callbacks were defined as passing "void *" as the second
argument, but were being implicitly cast to a new type. Replace the
argument with union nfsd4_op_u, and perform explicit member selection
in the function body. There are no resulting binary differences.

Add a tracepoint to capture the number of filecache-triggered fsync
calls and which files needed it. Also, record when an fsync triggers
a write verifier reset.
Examples:
<...>-97 [007] 262.505611: nfsd_file_free: inode=0xffff888171e08140 ref=0 flags=GC may=WRITE nf_file=0xffff8881373d2400
<...>-97 [007] 262.505612: nfsd_file_fsync: inode=0xffff888171e08140 ref=0 flags=GC may=WRITE nf_file=0xffff8881373d2400 ret=0
<...>-97 [007] 262.505623: nfsd_file_free: inode=0xffff888171e08dc0 ref=0 flags=GC may=WRITE nf_file=0xffff8881373d1e00
<...>-97 [007] 262.505624: nfsd_file_fsync: inode=0xffff888171e08dc0 ref=0 flags=GC may=WRITE nf_file=0xffff8881373d1e00 ret=0

The svc_ungetu32 function is not used, you could remove it.

We don't really care whether there are hashed entries when it comes to
scheduling the laundrette. They might all be non-gc entries, after all.
We only want to schedule it if there are entries on the LRU.
Switch to using list_lru_count, and move the check into
nfsd_file_gc_worker. The other callsite in nfsd_file_put doesn't need to
count entries, since it only schedules the laundrette after adding an
entry to the LRU.

RZ/G2L has separate IRQ lines for tx and error interrupt for each
channel whereas R-Car has a combined IRQ line for all the channel
specific tx and error interrupts.
Add multi_channel_irqs to struct rcar_canfd_hw_info to select the
driver to choose between combined and separate irq registration for
channel interrupts. This patch also removes enum rcanfd_chip_id and
chip_id from both struct rcar_canfd_hw_info, as it is unused.

R-Car has a clock divider for CAN FD clock within the IP, whereas
it is not available on RZ/G2L.
Add postdiv variable to struct rcar_canfd_hw_info to take care of this
difference.

RZ/G2L has separate IRQ lines for receive FIFO and global error interrupt
whereas R-Car has shared IRQ line.
Add shared_global_irqs to struct rcar_canfd_hw_info to select the driver to
choose between shared and separate irq registration for global
interrupts.
