If a hardware error occurs and the connections are flushed without a
disconnection_complete event being signaled, the temporary linkkeys are
not flushed.
This change ensures that any outstanding flushable linkkeys are flushed
when the connection are flushed from the hash table.
Additionally, this also makes use of test_and_clear_bit to avoid
multiple attempts to delete the link key that's already been flushed.

Use the presence of a DT property, "brcm,requires-autobaud-mode", to enable
startup in autobaud mode. If the property is present, the device is started
in autobaud mode by asserting RTS (BT_UART_CTS_N) prior to powering on the
device.
Also prevent the use of unsupported commands for devices started in
autobaud mode. Only a limited subset of HCI commands are supported in
autobaud mode.
Some devices (e.g. CYW5557x) require autobaud mode to enable FW loading.
Autobaud mode can also be required on some boards where the controller
device is using a non-standard baud rate in normal mode when first powered
on.

When trying to load modules built for RISC-V which include assembly files
the kernel loader errors with "unexpected relocation type 'R_RISCV_ALIGN'"
due to R_RISCV_ALIGN relocations being generated by the assembler.
The R_RISCV_ALIGN relocations can be removed at the expense of code space
by adding -mno-relax to gcc and as. In commit 7a8e7da422
("RISC-V: Fixes to module loading") -mno-relax is added to the build
variable KBUILD_CFLAGS_MODULE. See [1] for more info.
The issue is that when kbuild builds a .S file, it invokes gcc with
the -mno-relax flag, but this is not being passed through to the
assembler. Adding -Wa,-mno-relax to KBUILD_AFLAGS_MODULE ensures that
the assembler is invoked correctly. This may have now been fixed in
gcc[2] and this addition should not stop newer gcc and as from working.

This patch slightly reworks the s390 arch_get_random_seed_{int,long}
implementation: Make sure the CPACF trng instruction is never
called in any interrupt context. This is done by adding an
additional condition in_task().
Justification:
There are some constrains to satisfy for the invocation of the
arch_get_random_seed_{int,long}() functions:
- They should provide good random data during kernel initialization.
- They should not be called in interrupt context as the TRNG
instruction is relatively heavy weight and may for example
make some network loads cause to timeout and buck.
However, it was not clear what kind of interrupt context is exactly
encountered during kernel init or network traffic eventually calling
arch_get_random_seed_long().
After some days of investigations it is clear that the s390
start_kernel function is not running in any interrupt context and
so the trng is called:

The condition in_task() is true and the CPACF trng provides random data
during kernel startup.
The network traffic however, is more difficult. A typical call stack
looks like this:

Jann reported a race between munmap() and unmap_mapping_range(), where
unmap_mapping_range() will no-op once unmap_vmas() has unlinked the
VMA; however munmap() will not yet have invalidated the TLBs.
Therefore unmap_mapping_range() will complete while there are still
(stale) TLB entries for the specified range.
Mitigate this by force flushing TLBs for VM_PFNMAP ranges.

The previous patch removed the tlb_flush_end() implementation which
used tlb_flush_range(). This means:
- csky did double invalidates, a range invalidate per vma and a full
invalidate at the end
- csky actually has range invalidates and as such the generic
tlb_flush implementation is more efficient for it.

Scattered across the archs are 3 basic forms of tlb_{start,end}_vma().
Provide two new MMU_GATHER_knobs to enumerate them and remove the per
arch tlb_{start,end}_vma() implementations.
- MMU_GATHER_NO_FLUSH_CACHE indicates the arch has flush_cache_range()
but does *NOT* want to call it for each VMA.
- MMU_GATHER_MERGE_VMAS indicates the arch wants to merge the
invalidate across multiple VMAs if possible.
With these it is possible to capture the three forms:
1) empty stubs;
select MMU_GATHER_NO_FLUSH_CACHE and MMU_GATHER_MERGE_VMAS
2) start: flush_cache_range(), end: empty;
select MMU_GATHER_MERGE_VMAS
3) start: flush_cache_range(), end: flush_tlb_range();
default
Obviously, if the architecture does not have flush_cache_range() then
it also doesn't need to select MMU_GATHER_NO_FLUSH_CACHE.

Several devices integrated into LS7A report 1 (which means they use
INTA) in their Interrupt Pin registers, but they actually use a different
interrupt.
Add a quirk to override the incorrect Interrupt Pin values.
This is only needed by ACPI-based systems. For DT-based systems,
pci_assign_irq() ignores the Interrupt Pin register except to learn that
the device uses INTx and the host bridge .map_irq() function
(loongson_map_irq()) learns the IRQ mapping via DT and of_irq_parse_pci().
[bhelgaas: drop PCIE_PORT_x, OHCI, GPU since they are function 0 and don't
need the quirk, squash in updates from

Currently the command 'lx-symbols' in gdb exits with the error`Function
"do_init_module" not defined in "kernel/module.c"`. This occurs because
the file kernel/module.c was moved to kernel/module/main.c.
Fix this breakage by changing the path to "kernel/module/main.c" in
LoadModuleBreakpoint.

Sedat Dilek noticed that I had an extraneous semicolon at the end of a
line in the previous patch.
It's harmless, but unintentional, and while compilers just treat it as
an extra empty statement, for all I know some other tooling might warn
about it. So clean it up before other people notice too ;)

Add si-en compatibles for all chip variants and add conditionals
depending on compatibles to document variants specs:
- possible reg addresses
- whether audio-gain-db is supported or not
- maximum number of leds

The multi-led node defined address/size cells, so it is intended to have
children with unit addresses.
The second multi-led's reg property defined three LED indexes within one
reg item, which is not correct - these are three separate items.

To undo the all initialization from blk_mq_init_allocated_queue in case
of a probe failure where add_disk is never called we have to call
blk_mq_exit_queue from put_disk.
This relies on the fact that drivers always call blk_mq_free_tag_set
after calling put_disk in the probe error path if they have a gendisk
at all.
We should be doing this in general, but can't do it for the normal
teardown case (yet) as the tagset can be gone by the time the disk is
released once it was added. I hope to sort this out properly eventually
but for now this isolated hack will do it.
