media: rcar-vin: sync which hardware buffer to start capture from
When starting the VIN capture procedure we are not guaranteed that the
first buffer written to is VnMB1 to which we assigned the first buffer
queued. This is problematic for two reasons. Buffers might not be
dequeued in the same order they where queued for capture. Future
features planed for the VIN driver is support for outputting frames in
SEQ_TB/BT format and to do that it's important that capture starts from
the first buffer slot, VnMB1.
We are guaranteed that capturing always happens in sequence (VnMB1 ->
VnMB2 -> VnMB3 -> VnMB1). So drop up to two frames when starting
capturing so that the driver always returns buffers in the same order
they are queued and prepare for SEQ_TB/BT output.

efi/x86: Fix incorrect invocation of PciIo->Attributes()
The following commit:
2c3625cb9fa2 ("efi/x86: Fold __setup_efi_pci32() and __setup_efi_pci64() into one function")
... merged the two versions of __setup_efi_pciXX(), without taking into
account that the 32-bit version used a rather dodgy trick to pass an
immediate 0 constant as argument for a uint64_t parameter.
The issue is caused by the fact that on x86, UEFI protocol method calls
are redirected via struct efi_config::call(), which is a variadic function,
and so the compiler has to infer the types of the parameters from the
arguments rather than from the prototype.
As the 32-bit x86 calling convention passes arguments via the stack,
passing the unqualified constant 0 twice is the same as passing 0ULL,
which is why the 32-bit code in __setup_efi_pci32() contained the
following call:
status = efi_early->call(pci->attributes, pci,
EfiPciIoAttributeOperationGet, 0, 0,
&attributes);
to invoke this UEFI protocol method:
typedef
EFI_STATUS
(EFIAPI *EFI_PCI_IO_PROTOCOL_ATTRIBUTES) (
IN EFI_PCI_IO_PROTOCOL *This,
IN EFI_PCI_IO_PROTOCOL_ATTRIBUTE_OPERATION Operation,
IN UINT64 Attributes,
OUT UINT64 *Result OPTIONAL
);
After the merge, we inadvertently ended up with this version for both
32-bit and 64-bit builds, breaking the latter.
So replace the two zeroes with the explicitly typed constant 0ULL,
which works as expected on both 32-bit and 64-bit builds.
Wilfried tested the 64-bit build, and I checked the generated assembly
of a 32-bit build with and without this patch, and they are identical.

Pull powerpc fixes from Michael Ellerman:
- a fix for hugetlb with 4K pages, broken by our recent changes for
split PMD PTL.
- set the correct assembler machine type on e500mc, needed since
binutils 2.26 introduced two forms for the "wait" instruction.
- a fix for potential missed TLB flushes with MADV_[FREE|DONTNEED] etc.
and THP on Power9 Radix.
- three fixes to try and make our panic handling more robust by hard
disabling interrupts, and not marking stopped CPUs as offline because
they haven't been properly offlined.
- three other minor fixes.
Thanks to: Aneesh Kumar K.V, Michael Jeanson, Nicholas Piggin.

- clear buffers allocated with FORCE_CONTIGUOUS explicitly until the
CMA code honours __GFP_ZERO
- notrace annotation for secondary_start_kernel()
- use early_param() instead of __setup() for "kpti=" as it is needed
for the cpufeature callback remapping swapper to non-global mappings
- ensure writes to swapper are ordered wrt subsequent cache maintenance
