Fix typo in debug print. p1_base() should be p2_base(). No change other
than to the debug output.

Add CXL_KERNEL_API config option so drivers which depend on this new
functionality won't be enabled until this is visible.
This is useful for merging the cxlflash driver which comes in via the SCSI
tree. The cxlflash driver can depend on CXL_KERNEL_API, hence it won't be
enabled in the SCSI tree until this new config option is merged via the powerpc
tree. Hence all trees will be bisectable at all times.

When pnv_pci_ioda_fixup() is called during PHB fixup time, each PE in
the sorted list of PEs (phb::pe_dma_list) is iterated to setup the PE's
DMA32 space by pnv_ioda_setup_bus_dma() if the PE's DMA32 weight is bigger
than zero. The function also assigns all the subordinate PCI devices of
the PE's primary bus with the PE's DMA32 IOMMU table. It causes the PCI
devicess in the child PEs, which don't have DMA weight, receives wrong
IOMMU table and then IOMMU group.
The patch fixes above issue by more check on the PE's coverage and don't
assign IOMMU table to those PCI devices, which belong to the child PEs.
The problem was found on Firestone platform initially.

Current swap encoding in pte can't support large pfns
above 4TB. Change the swap encoding such that we put
the swap type in the PTE bits. Also add build checks
to make sure we don't overlap with HPTEFLAGS.

This patch changes the syscall handler to doom (tabort) active
transactions when a syscall is made and return very early without
performing the syscall and keeping side effects to a minimum (no CPU
accounting or system call tracing is performed). Also included is a
new HWCAP2 bit, PPC_FEATURE2_HTM_NOSC, to indicate this
behaviour to userspace.
Currently, the system call instruction automatically suspends an
active transaction which causes side effects to persist when an active
transaction fails.
This does change the kernel's behaviour, but in a way that was
documented as unsupported. It doesn't reduce functionality as
syscalls will still be performed after tsuspend; it just requires that
the transaction be explicitly suspended. It also provides a
consistent interface and makes the behaviour of user code
substantially the same across powerpc and platforms that do not
support suspended transactions (e.g. x86 and s390).
Performance measurements using
http://ozlabs.org/~anton/junkcode/null_syscall.c indicate the cost of
a normal (non-aborted) system call increases by about 0.25%.

Update the "IBM Power in-Nest Crypto Acceleration" and
"IBM Power 842 compression accelerator" sections to specify the correct
files.
The "IBM Power in-Nest Crypto Acceleration" was originally the only
NX driver, and so its section listed all drivers/crypto/nx/ files,
but now there is also the 842 driver which has its own section. This
lists explicitly what files are owned by the Crypto driver and which
files are owned by the 842 compression driver.

Add support to the nx-842-pseries.c driver for running in little endian
mode.

This adds cpu_to_be*() and be*_to_cpu() in the appropriate places to
work in LE mode also.

The struct aead_instance is meant to extend struct crypto_instance
by incorporating the extra members of struct aead_alg. However,
the current layout which is copied from shash/ahash does not specify
the struct fully. In particular only aead_alg is present.
For shash/ahash this works because users there add extra headroom
to sizeof(struct crypto_instance) when allocating the instance.
Unfortunately for aead, this bit was lost when the new aead_instance
was added.
Rather than fixing it like shash/ahash, this patch simply expands
struct aead_instance to contain what is supposed to be there, i.e.,
adding struct crypto_instance.
In order to not break existing AEAD users, this is done through an
anonymous union.

The struct crypto_alg is embedded into various type-specific structs
such as aead_alg. This is then used as part of instances such as
struct aead_instance. It is also embedded into the generic struct
crypto_instance. In order to ensure that struct aead_instance can
be converted to struct crypto_instance when necessary, we need to
ensure that crypto_alg is aligned properly.
This patch adds an alignment attribute to struct crypto_alg to
ensure this.
