All function declarations are "extern" by default, there is no need to
specify it explicitly.
For C99 states in 6.2.2.5:
"If the declaration of an identifier for a function has no
storage-class specifier, its linkage is determined exactly
as if it were declared with the storage-class specifier
extern."

The security offload function is performed by a cryptographic
engine core attached to the 128-bit PLB (processor local bus)
with builtin DMA and interrupt controllers. This, I think,
satisfies the requirement for the CRYPTO_ALG_KERN_DRIVER_ONLY
flag.

Using RBP as a temporary register breaks frame pointer convention and

Use R13 instead of RBP. Both are callee-saved registers, so the

Using RBP as a temporary register breaks frame pointer convention and
breaks stack traces when unwinding from an interrupt in the crypto code.
Mix things up a little bit to get rid of the RBP usage, without hurting
performance too much. Use RDI instead of RBP for the TBL pointer. That
will clobber CTX, so spill CTX onto the stack and use R12 to read it in
the outer loop. R12 is used as a non-persistent temporary variable
elsewhere, so it's safe to use.
Also remove the unused y4 variable.

Using RBP as a temporary register breaks frame pointer convention and
breaks stack traces when unwinding from an interrupt in the crypto code.
There's no need to use RBP as a temporary register for the TBL value,
because it always stores the same value: the address of the K256 table.
Instead just reference the address of K256 directly.

Use R15 instead of RBP. R15 can't be used as the RID1 register because
of x86 instruction encoding limitations. So use R15 for CTX and RDI for

Instead it needs to be explicitly copied from RDI.

During the change to use aligned buffers, the deallocation code path was
not updated correctly. The current code tries to free the aligned buffer
pointer and not the original buffer pointer as it is supposed to.
Thus, the code is updated to free the original buffer pointer and set
the aligned buffer pointer that is used throughout the code to NULL.
