Some hardware platform can support RAS Extension, but not support IESB,
such as Huawei's platform, so software need to insert Synchronization Barrier
operations at exception handler entry.
This series patches are based on James's series patches "SError rework +
RAS&IESB for firmware first support". In Huawei's platform, we do not
support IESB, so software needs to insert that.
Dongjiu Geng (3):
arm64: add a macro for SError synchronization
arm64: add error synchronization barrier in kernel_entry/kernel_exit
KVM: arm64: add ESB in exception handler entry and exit.
James Morse (18):
arm64: explicitly mask all exceptions
arm64: introduce an order for exceptions
arm64: Move the async/fiq helpers to explicitly set process context
flags
arm64: Mask all exceptions during kernel_exit
arm64: entry.S: Remove disable_dbg
arm64: entry.S: convert el1_sync
arm64: entry.S convert el0_sync
arm64: entry.S: convert elX_irq
KVM: arm/arm64: mask/unmask daif around VHE guests
arm64: kernel: Survive corrected RAS errors notified by SError
arm64: cpufeature: Enable IESB on exception entry/return for
firmware-first
arm64: kernel: Prepare for a DISR user
KVM: arm64: Set an impdef ESR for Virtual-SError using VSESR_EL2.
KVM: arm64: Save/Restore guest DISR_EL1
KVM: arm64: Save ESR_EL2 on guest SError
KVM: arm64: Handle RAS SErrors from EL1 on guest exit
KVM: arm64: Handle RAS SErrors from EL2 on guest exit
KVM: arm64: Take any host SError before entering the guest
Xie XiuQi (2):
arm64: entry.S: move SError handling into a C function for future
expansion
arm64: cpufeature: Detect CPU RAS Extentions
