Paolo Bonzini 7d41e24da2 KVM x86 misc changes for 6.10: ... - Advertise the max mappable GPA in the "guest MAXPHYADDR" CPUID field, which is unused by hardware, so that KVM can communicate its inability to map GPAs that set bits 51:48 due to lack of 5-level paging. Guest firmware is expected to use the information to safely remap BARs in the uppermost GPA space, i.e to avoid placing a BAR at a legal, but unmappable, GPA. - Use vfree() instead of kvfree() for allocations that always use vcalloc() or __vcalloc(). - Don't completely ignore same-value writes to immutable feature MSRs, as doing so results in KVM failing to reject accesses to MSR that aren't supposed to exist given the vCPU model and/or KVM configuration. - Don't mark APICv as being inhibited due to ABSENT if APICv is disabled KVM-wide to avoid confusing debuggers (KVM will never bother clearing the ABSENT inhibit, even if userspace enables in-kernel local APIC). -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEKTobbabEP7vbhhN9OlYIJqCjN/0FAmY+rlEACgkQOlYIJqCj N/3/xQ/7BvNl1aCJSIQy+yanCKK4wV0wWoY/hD+1wVge3zoaLZqLNHeR7fEa3vo+ OSS/pOz+PT6DbkokZYjjVaGs6+pFqaYg5YvRE7SPbj903phm81H7v5ZLtwgOBcXx dG9cSLTaRhos0PxqoiLfmiGK5IDKmWuZyJzhw+nPh2YmxoRDO/4exsLA9xWWhQSh BjPf32cq69fn39Mo/KeANdLR1FEjvKItEty7St5r/OZFxejP8VPe1xuFxHPJn4U+ FBbDe0DMXAPfoAQImBBhHUpm5Rp7Hwbh90tM8xY6rf3hvRZWmMCAX/Hx8C562M2b k6jB13gsoVesatT6lgKs2I0KGL7TSC0jLYG8aeREdBz6AEo5bkBegB5965MZYfGv T43i/zk+Ha5VIEURqE/CtocKF8AEjnUWLaIyL7VsDqaMslmaMdWzr8RouaO1snMT N/mfilzx9/rzltTV67TI8FSykPNxehwNoc9P8l+ulbW1KKIzpZCWxtIpQnT2TGdn 89zAJ7LUbEAOnO+jMsJjld0fcNEmUqiqu9tezHuu0rVYErYqtfVhrWIf52r0AHDK HRY5FNcZzCE+8FFAVDNl92Of+mPeF47RELXNMLAT+1lm91ug4k62GF4UDw7hsbFo 6+ductlj2DZlwxZVGKxKhBDxFg+AfsNCC1fZvYq+D/6ZE51eABo= =9RXP -----END PGP SIGNATURE----- Merge tag 'kvm-x86-misc-6.10' of https://github.com/kvm-x86/linux into HEAD KVM x86 misc changes for 6.10: - Advertise the max mappable GPA in the "guest MAXPHYADDR" CPUID field, which is unused by hardware, so that KVM can communicate its inability to map GPAs that set bits 51:48 due to lack of 5-level paging.
