VFs call adf_dev_stop() from a PF to VF interrupt bottom half.
This causes an oops "scheduling while atomic", because it tries
to acquire a mutex to un-register crypto algorithms.
This patch fixes the issue by calling adf_dev_stop() asynchronously.

The exact purpose of the len extension isn't clear to me, but due to
its form, I suspect that it's a leftover somehow accounting for leading
zero bytes within the most significant output limb.
Note however that without that len adjustement, the total number of bytes
ever processed by the inner loop equals nbytes and thus, the last output
limb gets written at this point. Thus the net effect of the len adjustement
cited above is just to keep the inner loop running for some more
iterations, namely < BYTES_PER_MPI_LIMB ones, reading some extra bytes from
beyond the last SGE's buffer and discarding them afterwards.
Fix this issue by purging the extension of len beyond the last input SGE's
buffer length.

Within the byte reading loop in mpi_read_raw_sgl(), there are two
housekeeping indices used, z and x.
At all times, the index z represents the number of output bytes covered
by the input SGEs for which processing has completed so far. This includes
any leading zero bytes within the most significant limb.
The index x changes its meaning after the first outer loop's iteration
though: while processing the first input SGE, it represents
"number of leading zero bytes in most significant output limb" +
"current position within current SGE"
For the remaining SGEs OTOH, x corresponds just to
"current position within current SGE"
After all, it is only the sum of z and x that has any meaning for the
output buffer and thus, the
"number of leading zero bytes in most significant output limb"
part can be moved away from x into z from the beginning, opening up the
opportunity for cleaner code.
Before the outer loop iterating over the SGEs, don't initialize z with
zero, but with the number of leading zero bytes in the most significant
output limb. For the inner loop iterating over a single SGE's bytes,
get rid of the buf_shift offset to x' bounds and let x run from zero to
sg->length - 1.

The number of bits, nbits, is calculated in mpi_read_raw_from_sgl() as
follows:
nbits = nbytes * 8;
Afterwards, the number of leading zero bits of the first byte get
subtracted:
nbits -= count_leading_zeros(*(u8 *)(sg_virt(sgl) + lzeros));
However, count_leading_zeros() takes an unsigned long and thus,
the u8 gets promoted to an unsigned long.
Thus, the above doesn't subtract the number of leading zeros in the most
significant nonzero input byte from nbits, but the number of leading
zeros of the most significant nonzero input byte promoted to unsigned long,
i.e. BITS_PER_LONG - 8 too many.
Fix this by subtracting
count_leading_zeros(...) - (BITS_PER_LONG - 8)
from nbits only.

At the very beginning of mpi_read_raw_from_sgl(), the leading zeros of
the input scatterlist are counted:
lzeros = 0;
for_each_sg(sgl, sg, ents, i) {
...
if (/* sg contains nonzero bytes */)
break;
/* sg contains nothing but zeros here */
ents--;
lzeros = 0;
}
Later on, the total number of trailing nonzero bytes is calculated by
subtracting the number of leading zero bytes from the total number of input
bytes:
nbytes -= lzeros;
However, since lzeros gets reset to zero for each completely zero leading
sg in the loop above, it doesn't include those.
Besides wasting resources by allocating a too large output buffer,
this mistake propagates into the calculation of x, the number of
leading zeros within the most significant output limb:
x = BYTES_PER_MPI_LIMB - nbytes % BYTES_PER_MPI_LIMB;
What's more, the low order bytes of the output, equal in number to the
extra bytes in nbytes, are left uninitialized.
Fix this by adjusting nbytes for each completely zero leading scatterlist
entry.

and moves memory around to purge leading zero limbs afterwards.
However, with
commit 9cbe21d8f8 ("lib/mpi: only require buffers as big as needed for

the caller is only required to provide a buffer large enough to hold the
result without the leading zeros.
This might result in a buffer overflow for small MP numbers with leading
zeros.
Fix this by coping the result to its final destination within the output
buffer and not copying the leading zeros at all.

mpi_limb_t *limb2 = (void *)p - sizeof(alimb)

}
where p points past the end of alimb2 which lives on the stack and contains
the current limb in BE order.
The purpose of the above is to shift the non-zero bytes of alimb2 to its
beginning in memory, i.e. to skip its leading zero bytes.
However, limb2 points somewhere into the middle of alimb2 and thus, reading
*limb2 pulls in lzero bytes from somewhere.
