Subject: [PATCH V3 0/5] Support for 64bit hartid on RV64 platforms

The hartid can be a 64bit value on RV64 platforms. This series updates
the code so that 64bit hartid can be supported on RV64 platforms.

The series has been tested on both RV32 and RV64 qemu platforms.

Changes since V2:
	1) Modified commit messages to mention RV64 and add RB tags.

Changes since V1:
	1) Updated RB tag for PATCH 1 and PATCH3
	2) Type Casting NR_CPUS before comparing with hartid in PATCH 2
	3) Changed commit message of PATCH 2 to provide details about
	   the bug it is fixing.
	4) Updated PATCH 5 for unaligned 64bit read


Sunil V L (5):
  riscv: cpu_ops_sbi: Add 64bit hartid support on RV64
  riscv: spinwait: Fix hartid variable type
  riscv: smp: Add 64bit hartid support on RV64
  riscv: cpu: Add 64bit hartid support on RV64
  riscv/efi_stub: Add 64bit boot-hartid support on RV64
