Function sunrise_kernel::cpu_locals::init_cpu_locals

pub fn init_cpu_locals(cpu_count: usize)

Initializes cpu locals during early boot stage.

• Maps the kernel's ELF to get our PT_TLS program header information, including the TLS initialization image.
• Allocates an array of cpu_count cpu local regions and stores them in CPU_LOCAL_REGIONS.
• Makes this core's KTls segment point to CPU_LOCAL_REGIONS[0]'s ThreadControlBlock.

Panics

• Failed to map kernel's ELF.
• Failed to get kernel ELF's TLS initialization image.
