As the AEAD conversion is still ongoing, we do not yet wish to
export legacy AEAD implementations to user-space, as their calling
convention will change.
This patch actually disables all AEAD algorithms because some of
them (e.g., cryptd) will need to be modified to propagate this flag.
Subsequent patches will reenable them on an individual basis.

The bit CRYPTO_ALG_INTERNAL was added to stop af_alg from accessing
internal algorithms. However, af_alg itself was never modified to
actually stop that bit from being used by the user. Therefore the
user could always override it by specifying the relevant bit in the
type and/or mask.
This patch silently discards the bit in both type and mask.

The RNG may not be available during early boot, e.g., the relevant
modules may not be included in the initramfs. As the RNG Is only
needed for IPsec, we should not let this prevent use of ciphers
without IV generators, e.g., for disk encryption.
This patch postpones the RNG allocation to the init function so
that one failure during early boot does not make the RNG unavailable
for all subsequent users of the same cipher.
More importantly, it lets the cipher live even if RNG allocation
fails. Of course we no longer offer IV generation and which will
fail with an error if invoked. But all other cipher capabilities
will function as usual.

Currently we free the default RNG when its use count hits zero.
This was OK when the IV generators would latch onto the RNG at
instance creation time and keep it until the instance is torn
down.
Now that IV generators only keep the RNG reference during init
time this scheme causes the default RNG to come and go at a high
frequencey. This is highly undesirable as we want to keep a single
RNG in use unless the admin wants it to be removed.
This patch changes the scheme so that the system RNG once allocated
is never removed unless a specifically requested.

Currently for skcipher IV generators they must provide givencrypt
as that is the whole point. We are currently replacing skcipher
IV generators with explicit IV generators. In order to maintain
backwards compatibility, we need to allow the IV generators to
still function as a normal skcipher when the RNG Is not present
(e.g., in the initramfs during boot). IOW everything but givencrypt
and givdecrypt will still work but those two will fail.
Therefore this patch assigns a default givencrypt that simply
returns an error should it be NULL.

ext4 isn't willing to map clusters to a non-extent file. Don't signal
this with an out of space error, since the FS will retry the
allocation (which didn't fail) forever. Instead, return EUCLEAN so
that the operation will fail immediately all the way back to userspace.
(The fix is either to run e2fsck -E bmap2extent, or to chattr +e the file.)

We no longer calculate the minimum freelist size from the on-disk
AGF, so we don't need the macros used for this. That means the
nested macros can be cleaned up, and turn this into an actual
function so the logic is clear and concise. This will make it much
easier to add support for the rmap btree when the time comes.
This also gets rid of the XFS_AG_MAXLEVELS macro used by these
freelist macros as it is simply a wrapper around a single variable.

At the moment, xfs_alloc_fix_freelist() uses a mix of per-ag based
access and agf buffer based access to freelist and space usage
information. However, once the AGF buffer is locked inside this
function, it is guaranteed that both the in-memory and on-disk
values are identical. xfs_alloc_fix_freelist() doesn't modify the
values in the structures directly, so it is a read-only user of the
infomration, and hence can use the per-ag structure exclusively for
determining what it should do.
This opens up an avenue for cleaning up a lot of duplicated logic
whose only difference is the structure it gets the data from, and in
doing so removes a lot of needless byte swapping overhead when
fixing up the free list.

If we create a CRC filesystem, mount it, and create a symlink with
a path long enough that it can't live in the inode, we get a very
strange result upon remount:
# ls -l mnt
total 4
lrwxrwxrwx. 1 root root 929 Jun 15 16:58 link -> XSLM
XSLM is the V5 symlink block header magic (which happens to be
followed by a NUL, so the string looks terminated).
xfs_readlink_bmap() advanced cur_chunk by the size of the header
for CRC filesystems, but never actually used that pointer; it
kept reading from bp->b_addr, which is the start of the block,
rather than the start of the symlink data after the header.
Looks like this problem goes back to v3.10.
Fixing this gets us reading the proper link target, again.

As of commit 34b1252bd91851f77f89fbb6829a04efad900f41 ("MIPS:
Cobalt: Do not build MTD platform device registration code as module.")
this file became built-in instead of modular. So we should also
stop using module_init as an alias for __initcall as that can be
rather misleading.
Fix this up now, so that we can relocate module_init from
init.h into module.h in the future. If we don't do this, we'd
have to add module.h to obviously non-modular code, and that
would be a worse thing.
Direct use of __initcall is discouraged, vs prioritized ones.
Use of device_initcall is consistent with what __initcall
maps onto, and hence does not change the init order, making the
impact of this change zero.

After Broadcom switched from MIPS to ARM for their home routers we need
to have NVRAM driver in some common place (not arch/mips/). As explained
in Kconfig, this driver is responsible for parsing SoC configuration
data that is passed to the kernel in flash from the bootloader firmware
called "CFE".
We were thinking about putting it in bus directory, however there are
two possible buses for MIPS: drivers/ssb/ and drivers/bcma/. So this
won't fit there and this is why I would like to move this driver to the
drivers/firmware/.

This replaces the plain loop over the sglist array with for_each_sg()
macro which consists of sg_next() function calls. Since MIPS doesn't
select ARCH_HAS_SG_CHAIN, it is not necessary to use for_each_sg() in
order to loop over each sg element. But this can help find problems
with drivers that do not properly initialize their sg tables when
CONFIG_DEBUG_SG is enabled.

This simplifies code just a bit (also maybe makes it a bit more
intuitive?) and will allow us to stop storing header. Right now we copy
whole NVRAM including its header to the internal buffer. It is not
needed to store a header as we don't access all these details like CRC,
flags, etc. The next improvement that should follow is copying only the

allocate_irqno, free_irqno and alloc_legacy_irqno are a simple allocator
for interrupt numbers from the days when the numer of interrupts was still
fixed to NR_IRQS. This was necessary for the SGI IP27 architecture which
with its flexible architecture and possibly large number of interrupts
doesn't easily fit into the old pattern. These days there are better
alternatives.
Move the allocation code from the arch generic code to the only platform
using it, the SGI IP27 aka Origin 200/2000, Onyx 2.

Repleace smp_mb() in arch_write_unlock() and __clear_bit_unlock() to

It seems like it was missed in commit f252ffd50c97dae87b45f1dbad24f71358ccfbd6
during introduction of "acquire" and "release" semantics.
[ralf@linux-mips: The original patch submission was labelled a fix but
actually it replaces a barrier with another less restrictive type of
barrier so it doesn't fix any ill behaviour but rather squeezes out a
tad better performance. Further improvments will be possible once
smp_release() has been merged.]

This commit introduces BPF ASM helpers for MIPS and MIPS64 kernels.
The purpose of this patch is to twofold:
1) We are now able to handle negative offsets instead of either
falling back to the interpreter or to simply not do anything and
bail out.
2) Optimize reads from the packet header instead of calling the C
helpers
Because of this patch, we are now able to get rid of quite a bit of
code in the JIT generation process by using MIPS optimized assembly
code. The new assembly code makes the test_bpf testsuite happy with
all 60 test passing successfully compared to the previous
implementation where 2 tests were failing.
Doing some basic analysis in the results between the old
implementation and the new one we can obtain the following
summary running current mainline on an ER8 board (+/- 30us delta is
ignored to prevent noise from kernel scheduling or IRQ latencies):
Summary: 22 tests are faster, 7 are slower and 47 saw no improvement
with the most notable improvement being the tcpdump tests. The 7 tests
that seem to be a bit slower is because they all follow the slow path
(bpf_internal_load_pointer_neg_helper) which is meant to be slow so
that's not a problem.
