Adds caching of the OP-TEE argument structure used to pass request to secure world. This reduces quite a bit of unnecessary alloc/free and possibly switching back and forth to secure work in order to register the buffers in some configurations, most notably FF-A. -----BEGIN PGP SIGNATURE----- iQJOBAABCgA4FiEEFV+gSSXZJY9ZyuB5LinzTIcAHJcFAmJy2qcaHGplbnMud2lr bGFuZGVyQGxpbmFyby5vcmcACgkQLinzTIcAHJfGvRAAwWWyMSRRxFGlaiENphwg vLKP0faPgW4kBPLI7bd6ItpWlMNNx6ixtqZo8Icz0yke7yb/5m1wi3jC1rz2FuvU JZXdepakJ3TGDpXWX6wVSpZFGfq/l41OTmFh3BV3DvUCMTfjXzcUJqv9zHpWwgU/ qPY/hhWzrJcJ8fTi6tXtExAhUsGxAmSJ/s+ShvNYXbNa8hrgyU3Nq15HODGR1BXS +2mos1F4KlGRxhPu+hCRqyyD5l3Tkzk4HFoSt6AOfBQ9voSCcw8XVtL9/4Jx3592 +99Y+VqsnJJNEHiSD6ESRyKadRIZvH4zwKBh92J3z/NhhxmeC1isDFYkmlgoxCaq OgPdFUa0Nq3JlIY4W+0c3TS0N/CGXrRFkDChEbn4sdQOKeIUy70yX/Eml5d+xhAC JDnSzz/B6i8qYgXwK6srSiY2uKi75L4qhGQmemp1x4HToRjEjTfWaKX2rBjfspiQ 8/9HQBG7Xk1PYiAN0z4xIjpoYqMRLwrtGm7J0Ep8/PKFyr+yzIHkYLFtoWGv9PZa F23/muMZALUxCLwm03/WmlFqmEeY2cFh/dB6UBIVpBmTM3X7QPdrTwVpamLgmtyT hwONAOpmUGF6du0a84Gz2D3unUaGXGI8Ccyam2MsYYQF9vwxp0HU/Q08zR69vMJA BmVbSlUfIPcMLOP0xamfrx4= =vq/I -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEo6/YBQwIrVS28WGKmmx57+YAGNkFAmJz2LIACgkQmmx57+YA GNltcBAAws2PU8EbtUoyYsJlClc1lxj+pUfT9snyv8CJVSLV6a+c94EUrxApJiZv HWyNrGfjRCY0otXzI+uFz9VbRC7sOWZNygdK0oDu+P9kkRNqzqdzfD366ms/VOGJ cswKla5iqKWThkBM4jA2aZA6YdXg4yHjU5h529K5kd/MlW4FyPrN11Bj3ELMeqH5 XaPkbGMoUgOTkk2CA/9VxVJz2n3fIvXXPYox2fsaDeNJIv3Y0GLEZSC0qE79lve5 kALRxoHfawyTkHtmVu+3btaUDyjoopRXP0oxo2e3kssGoOUpCJ5OJ8FQhiCiTWXi dXE0U7HdM1NNfUSwo87BaE64oMaAULd1OJsOsPkTzzJwvHlcSewAip2y0dd5N7N9 ngcfBKWo+D17dVNKCVgA7rATMP5se2wtx2/u2TGsyOTmqhteR3hXznHVRm8ZrHCy yjtj/5SCqQL9/0/jRGLUR0BwhL0K8+zpW56uQ28cy1a9j7E5iROnrHRmqE6fYaaF /sD08lGaeqRKRuIJxFe0OVpQlgVN4ZL75dkujS7OUCrtI++No3QzCjlkSnLdNKdk +UB8r3NNPrZSWqdz87Otd+8T6nt7NBbGK/R2yZMtYy1l532VFLguJvRzuY75J8ks 8LgvZ0AumWRJbig+WdTulanXneAKgugpdwLGfDzNUt8P1nnjVE4= =XEqq -----END PGP SIGNATURE----- Merge tag 'optee-rpc-arg-for-v5.19' of https://git.linaro.org/people/jens.wiklander/linux-tee into arm/drivers OP-TEE RPC argument cache Adds caching of the OP-TEE argument structure used to pass request to secure world.

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 Restructured Text 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.
