Hi all,
This is a not-yet complete series to harden Xen for later revision of
Armv8. The main goals are:
- Reducing the number of BUG_ON() to check guest state
- Fix system registers size as they are always 64-bit on AArch64
(not 32-bit!).
There are more work to do. I will send them in smaller batch as I find
spare time to rework bits of Xen.
Note that patch #1 was already sent separately but added here for convenience.
Cheers,
Julien Grall (7):
xen/public: arch-arm: Restrict the visibility of struct
vcpu_guest_core_regs
xen/arm: SCTLR_EL1 is a 64-bit register on Arm64
xen/arm: Rework psr_mode_is_32bit()
xen/arm: traps: Avoid using BUG_ON() in _show_registers()
xen/arm: traps: Avoid BUG_ON() in do_trap_brk()
xen/arm: vsmc: The function identifier is always 32-bit
xen/arm: types: Specify the zero padding in the definition of
PRIregister
