*	arm64: Use the Linux sigframe to restore registers	Andrew Turner	2023-10-27	1	-1/+0
\| \| \| \| \| \| \| \| \| \| \|	When returning from a Linux signal use the Linux sigframe to find the register values to restore. Remove the FreeBSD ucontext from the stack as it's now unneeded.

*	linux(4): Implement signal trampoline for arm64 in a FreeBSD-way	Dmitry Chagin	2022-05-15	1	-11/+51
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	The implemenation differs from others Linuxulators. For unwinders Linux ucontext_t is stored, however native machine context is used to store/restore process state to avoid code duplication. As DWARF Aarch64 does not define a register number for PC and provides no direct way to encode the PC of the previous frame, CFI cannot describe a signal trampoline frame. So, modified the vdso linker script to discard unused sections. Extensions are not implemented. MFC after: 2 weeks
*	linux(4): Move sigframe definitions to separate headers	Dmitry Chagin	2022-05-15	1	-0/+44
	The signal trampoine-related definitions are used only in the MD part of code, wherefore moved from everywhere used linux.h to separate MD headers. MFC after: 2 weeks
