Subject: [PATCH 1/6] librtas: expose low-level RTAS call APIs internally
|
|
|
|
Make these functions available outside of syscall_calls.c, marking
|
|
them hidden so that they aren't exposed in the library ABI.
|
|
|
|
The implementations of librtas APIs will move into separate C files as
|
|
they gain support for new interfaces offered by the kernel.
