2024-07-02kernel: proc: Remove PROC_INEXEC flagIan Moffett

2024-07-02kernel/amd64: Handle the user GS segment registerIan Moffett
This commit introduces usage of swapgs to switch out the GS register with the user GS register. An md_td_kick() function is also introduced to start up user threads. The this_cpu() function uses the GS register to read the current CPU structure using a new "self" field. Signed-off-by: Ian Moffett <ian@osmora.org>
