If an io error occurs on an io issued while connecting, recovery
of the io falls flat as the state checking ends up nooping the error
handler.
Create an err_work work item that is scheduled upon an io error while
connecting. The work thread terminates all io on all queues and marks
the queues as not connected. The termination of the io will return
back to the callee, which will then back out of the connection attempt
and will reschedule, if possible, the connection attempt.
The changes:
- in case there are several commands hitting the error handler, a
state flag is kept so that the error work is only scheduled once,
on the first error. The subsequent errors can be ignored.
- The calling sequence to stop keep alive and terminate the queues
and their io is lifted from the reset routine. Made a small
service routine used by both reset and err_work.
- During debugging, found that the teardown path can reference
an uninitialized pointer, resulting in a NULL pointer oops.
The aen_ops weren't initialized yet. Add validation on their
initialization before calling the teardown routine.

Currently, efi_mem_reserve_persistent() may not be called from atomic

The kmalloc() call is easy enough to fix, but the memremap() call
needs to be moved into an init hook since we cannot control the
memory allocation behavior of memremap() at the call site.

The new memory EFI reservation feature we introduced to allow memory
reservations to persist across kexec may trigger an unbounded number
of calls to memblock_reserve(). The memblock subsystem can deal with
this fine, but not before memblock resizing is enabled, which we can
only do after paging_init(), when the memory we reallocate the array
into is actually mapped.
So break out the memreserve table processing into a separate routine
and call it after paging_init() on arm64. On ARM, because of limited
reviewing bandwidth of the maintainer, we cannot currently fix this,
so instead, disable the EFI persistent memreserve entirely on ARM so
we can fix it later.

Commit:
24d7c494ce ("efi/arm-stub: Round up FDT allocation to mapping size")
increased the allocation size for the FDT image created by the stub to a
fixed value of 2 MB, to simplify the former code that made several
attempts with increasing values for the size. This is reasonable
given that the allocation is of type EFI_LOADER_DATA, which is released
to the kernel unless it is explicitly memblock_reserve()d by the early
boot code.
However, this allocation size leaked into the 'size' field of the FDT
header metadata, and so the entire allocation remains occupied by the
device tree binary, even if most of it is not used to store device tree
information.
So call fdt_pack() to shrink the FDT data structure to its minimum size
after populating all the fields, so that the remaining memory is no
longer wasted.

Commit:
3ea86495ae ("efi/arm: preserve early mapping of UEFI memory map longer for BGRT")
deferred the unmap of the early mapping of the UEFI memory map to
accommodate the ACPI BGRT code, which looks up the memory type that
backs the BGRT table to validate it against the requirements of the UEFI spec.
Unfortunately, this causes problems on ARM, which does not permit
early mappings to persist after paging_init() is called, resulting
in a WARN() splat. Since we don't support the BGRT table on ARM anway,
let's revert ARM to the old behaviour, which is to take down the
early mapping at the end of efi_init().

While running a nested guest VCPU on L0 via H_ENTER_NESTED hcall, a
pending signal in the L0 QEMU process can generate the following
sequence:
ret0 = kvmppc_pseries_do_hcall()
ret1 = kvmhv_enter_nested_guest()
ret2 = kvmhv_run_single_vcpu()
if (ret2 == -EINTR)
return H_INTERRUPT
if (ret1 == H_INTERRUPT)
kvmppc_set_gpr(vcpu, 3, 0)
return -EINTR
/* skipped: */
kvmppc_set_gpr(vcpu, 3, ret)
vcpu->arch.hcall_needed = 0
return RESUME_GUEST
which causes an exit to L0 userspace with ret0 == -EINTR.
The intention seems to be to set the hcall return value to 0 (via
VCPU r3) so that L1 will see a successful return from H_ENTER_NESTED
once we resume executing the VCPU. However, because we don't set
vcpu->arch.hcall_needed = 0, we do the following once userspace
resumes execution via kvm_arch_vcpu_ioctl_run():
...
} else if (vcpu->arch.hcall_needed) {
int i
kvmppc_set_gpr(vcpu, 3, run->papr_hcall.ret);
for (i = 0; i < 9; ++i)
kvmppc_set_gpr(vcpu, 4 + i, run->papr_hcall.args[i]);
vcpu->arch.hcall_needed = 0;
since vcpu->arch.hcall_needed == 1 indicates that userspace should
have handled the hcall and stored the return value in
run->papr_hcall.ret. Since that's not the case here, we can get an
unexpected value in VCPU r3, which can result in
kvmhv_p9_guest_entry() reporting an unexpected trap value when it
returns from H_ENTER_NESTED, causing the following register dump to
console via subsequent call to kvmppc_handle_exit_hv() in L1:

Pull RISC-V fixes from Palmer Dabbelt:
"This contains a few patches that fix various issues in the RISC-V
port:
- enable printk timestamps in the RISC-V defconfig.
- a whitespace fix to "struct pt_regs".
- add a "vdso_install" target for RISC-V.
- a pair of build fixes: one to fix a typo in our makefile, and one
to clean up some warnings.
There will probably be more patches from us for 4.20, but I don't have
anything that's ready to go right now so I'm going to hold off a bit.
Right now the only concrete thing I know I want to make sure gets
sorted out is our 32-bit stat interface, which I don't want sitting in
limbo for another cycle as we have to get RV32I glibc sone"

This will clear the USB_PORT_FEAT_C_CONNECTION bit in case of a hub port reset
only if a device is was attached to the hub port before resetting the hub port.
Using a Lenovo T480s attached to the ultra dock it was not possible to detect
some usb-c devices at the dock usb-c ports because the hub_port_reset code
will clear the USB_PORT_FEAT_C_CONNECTION bit after the actual hub port reset.
Using this device combo the USB_PORT_FEAT_C_CONNECTION bit was set between the
actual hub port reset and the clear of the USB_PORT_FEAT_C_CONNECTION bit.
This ends up with clearing the USB_PORT_FEAT_C_CONNECTION bit after the
new device was attached such that it was not detected.
This patch will not clear the USB_PORT_FEAT_C_CONNECTION bit if there is
currently no device attached to the port before the hub port reset.
This will avoid clearing the connection bit for new attached devices.

Audio map are possible in wrong state before card->instantiated has
been set to true. Imaging the following examples:
time 1: at the beginning
in:-1 in:-1 in:-1 in:-1
out:-1 out:-1 out:-1 out:-1
SIGGEN A B Spk
time 2: after someone called snd_soc_dapm_new_widgets()
(e.g. create_fill_widget_route_map() in sound/soc/codecs/hdac_hdmi.c)
in:1 in:0 in:0 in:0
out:0 out:0 out:0 out:1
SIGGEN A B Spk
time 3: routes added
in:1 in:0 in:0 in:0
out:0 out:0 out:0 out:1
SIGGEN -----> A -----> B ---> Spk
In the end, the path should be powered on but it did not. At time 3,
"in" of SIGGEN and "out" of Spk did not propagate to their neighbors
because snd_soc_dapm_add_path() will not invalidate the paths if
the card has not instantiated (i.e. card->instantiated is false).
To correct the state of audio map, recalculate the whole map forcely.

SMC-D stress workload showed connection stalls. Since the firmware
decides to skip raising an interrupt if the SBA DMBE mask bit is
still set, this SBA DMBE mask bit should be cleared before the
IRQ handling in the SMC code runs. Otherwise there are small windows
possible with missing interrupts for incoming data.
SMC-D currently does not care about the old value of the SBA DMBE
mask.

first bad commit: [0f688ab20a540aafa984c5dbd68a71debebf4d7f] Merge remote-tracking branch 'net-next/master'
and a diff between a working kernel does not reveal anything which would
explain the change in behavior.
Further investigation showed that on the second try of loading fails
because the dai_link->platform is no longer NULL and it might be pointing
to uninitialized memory.
The fix is to move the snd_soc_dai_link and snd_soc_card inside of the
abe_twl6040 struct, which is dynamically allocated every time the driver
probes.
