This patchset tries to fix some problem in current implementation for pointer mask, and add support for pointer mask of instruction fetch.

The port is available here:
https://github.com/plctlab/plct-qemu/tree/plct-pm-fix-v2

v2:
* drop some error patchs
* Add patch 2 and 3 to fix the new problems
* Add patch 4 and 5 to use PC-relative translation for pointer mask for instruction fetch

Weiwei Li (5):
  target/riscv: Fix pointer mask transformation for vector address
  target/riscv: Update cur_pmmask/base when xl changes
  target/riscv: Sync cpu_pc before update badaddr
  target/riscv: Add support for PC-relative translation
  target/riscv: Add pointer mask support for instruction fetch
