Subject: [PATCH] hvf: arm: Fix encodings for ID_AA64PFR1_EL1 and debug System
registers
We wrongly encoded ID_AA64PFR1_EL1 using {3,0,0,4,2} in hvf_sreg_match[] so
we fail to get the expected ARMCPRegInfo from cp_regs hash table with the
wrong key.
Fix it with the correct encoding {3,0,0,4,1}. With that fixed, the Linux
guest can properly detect FEAT_SSBS2 on my M1 HW.
All DBG{B,W}{V,C}R_EL1 registers are also wrongly encoded with op0 == 14.
It happens to work because HVF_SYSREG(CRn, CRm, 14, op1, op2) equals to
HVF_SYSREG(CRn, CRm, 2, op1, op2), by definition. But we shouldn't rely on
it.
