A number of functions in this file have large structures on the stack, ccp_run_aes_gcm_cmd() being the worst, in particular when KASAN is enabled on gcc: drivers/crypto/ccp/ccp-ops.c: In function 'ccp_run_sha_cmd': drivers/crypto/ccp/ccp-ops.c:1833:1: error: the frame size of 1136 bytes is larger than 1024 bytes [-Werror=frame-larger-than=] drivers/crypto/ccp/ccp-ops.c: In function 'ccp_run_aes_gcm_cmd': drivers/crypto/ccp/ccp-ops.c:914:1: error: the frame size of 1632 bytes is larger than 1024 bytes [-Werror=frame-larger-than=] Avoid the issue by using dynamic memory allocation in the worst one of these.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
