Mitchell Horne 6ae48dd870 Fix global pointer relaxations in the RISC-V kernel ... The gp register is intended to used by the linker as another means of performing relaxations, and should point to the small data section (.sdata). Currently gp is being used as the pcpu pointer within the kernel, but the more appropriate choice for this is the tp register, which is unused. Swap existing usage of gp with tp within the kernel, and set up gp properly at boot with the value of __global_pointer$ for all harts. Additionally, remove some cases of accessing tp from the PCB, as it is not part of the per-thread state. The user's tp and gp should be tracked only through the trapframe.
