Subject: [PATCH v2 0/8] crypto: kernel-doc for assembly language
Clean up the existing kernel-doc headers in the crypto subsystem,
then add support for kernel-doc headers in assembly language files
for functions called from C code.
This provides a place to document the assumptions made by the
assembly language functions about their arguments (e.g., how
they handle length values of 0, less than some value, not
multiples of some value, etc.).
Not all the assembly language files are tackled yet - just some
of the x86 files pending changes related to kernel_fpu_begin/end.
Changes in patch series v2:
* rebased to upstream after Herbert's v6.2-p1 tag was merged
* made not dependent on any of the proposed FPU patches
(instead, those will assume this is in place)
* adds Documentation for the new kernel-doc Prototype line
Example man page formatted output for one of them:

NAME
sha1_transform_avx2 - Calculate SHA1 hash using the x86 AVX2 feature
set
SYNOPSIS
void sha1_transform_avx2 (u32 *digest , const u8 *data , int blocks );
ARGUMENTS

tiple of 64 bytes
blocks number of 64-byte blocks (rdx, CNT macro)
DESCRIPTION
This function supports 64-bit CPUs.
RETURN
none
