+- mask event
+- handle event and clear event (the order does not matter)
+- unmask event
+
+It is not possible to implement this flow with handle_edge_irq, so
+switch back to handle_fasteoi_irq. Please note that Xen event irqs are
+ONESHOT. Also note that handle_fasteoi_irq was in-use before the
+following commit, that is partially reverted by this patch:
+
+7e186bdd0098 xen: do not clear and mask evtchns in __xen_evtchn_do_upcall
+
+PIRQ handling is left unchanged.
+
+This patch fixes a domU hang observed when using LinuxRT as dom0 kernel.

+Subject: [PATCH] xen/arm: Missing N1/A76/A75 FP registers in vCPU context
+ switch
+
+Xen has cpu_has_fp/cpu_has_simd to detect whether the CPU supports
+FP/SIMD or not. But currently, these two MACROs only consider value 0
+of ID_AA64PFR0_EL1.FP/SIMD as FP/SIMD features enabled. But for CPUs
+that support FP/SIMD and half-precision floating-point arithmetic, the
+ID_AA64PFR0_EL1.FP/SIMD are 1 (see Arm ARM DDI0487F.b, D13.2.64).
+For these CPUs, xen will treat them as no FP/SIMD support, the
+vfp_save/restore_state will not take effect.
+
+From the TRM documents of Cortex-A75/A76/N1, we know these CPUs support
+basic Advanced SIMD/FP and half-precision floating-point arithmetic. In
+this case, on N1/A76/A75 platforms, Xen will always miss the floating
+pointer registers save/restore. If different vCPUs are running on the
+same pCPU, the floating pointer registers will be corrupted randomly.
+
+This patch fixes Xen on these new cores.

-Subject: [PATCH] arm/arm64: xen: Fix to convert percpu address to gfn
- correctly
-
-Use per_cpu_ptr_to_phys() instead of virt_to_phys() for per-cpu
-address conversion.
-
-In xen_starting_cpu(), per-cpu xen_vcpu_info address is converted
-to gfn by virt_to_gfn() macro. However, since the virt_to_gfn(v)
-assumes the given virtual address is in linear mapped kernel memory
-area, it can not convert the per-cpu memory if it is allocated on
-vmalloc area.
-
-This depends on CONFIG_NEED_PER_CPU_EMBED_FIRST_CHUNK.
-If it is enabled, the first chunk of percpu memory is linear mapped.
-In the other case, that is allocated from vmalloc area. Moreover,
-if the first chunk of percpu has run out until allocating
-xen_vcpu_info, it will be allocated on the 2nd chunk, which is
-based on kernel memory or vmalloc memory (depends on
-CONFIG_NEED_PER_CPU_KM).
-
-Without this fix and kernel configured to use vmalloc area for
-the percpu memory, the Dom0 kernel will fail to boot with following
-errors.

-Subject: [PATCH] arm/xen: Don't probe xenbus as part of an early initcall
-
-commit c4295ab0b485b8bc50d2264bcae2acd06f25caaf upstream.
-
-After Commit 3499ba8198cad ("xen: Fix event channel callback via
-INTX/GSI"), xenbus_probe() will be called too early on Arm. This will
-recent to a guest hang during boot.
-
-If the hang wasn't there, we would have ended up to call
-xenbus_probe() twice (the second time is in xenbus_probe_initcall()).
-
-We don't need to initialize xenbus_probe() early for Arm guest.
-Therefore, the call in xen_guest_init() is now removed.
-
-After this change, there is no more external caller for xenbus_probe().
-So the function is turned to a static one. Interestingly there were two
-prototypes for it.
-

-### Run:
-To Run the Fixed Virtual Platform simulation tool you must download "Armv8-A
-Foundation Platform" from Arm developer (This might require the user to
-register) from this address:
-https://developer.arm.com/tools-and-software/simulation-models/fixed-virtual-platforms
-and install it on your host PC.

-
-Armv8‑A Foundation Platform User Guide:
-https://developer.arm.com/docs/100961/latest/
-
-
-Once done, do the following to build and run an image:
-```bash$ bitbake core-image-minimal```
-```bash$ export YOCTO_DEPLOY_IMGS_DIR="<yocto-build-dir/tmp/deploy/images/foundation-v8>"```
-```bash$ cd <path-to-Foundation_Platformpkg-dir/models/Linux64_GCC-X.X/>```

-bash$ ./Foundation_Platform --cores=4 --no-sve --gicv3 \

-         --block-device=${YOCTO_DEPLOY_IMGS_DIR}/core-image-minimal-foundation-armv8.disk.img

-
-If you have built a configuration without a ramdisk, you can use the following
-command in U-boot to start Linux:
-```VExpress64# booti 0x80080000 - 0x83000000```

+Subject: [PATCH 3/3] FF-A: Fix to fetch proper vCPU index for UP SP
+
+When switching the context between SPs, fetch the vCPU index using
+api_vm_get_vcpu() helper routine. This routine gets the vCPU at index 0
+for UP SP.
+
+Rename function api_ffa_msg_send_direct_get_receiver_vcpu() to
+api_vm_get_vcpu() as it is used both in direct message request
+and response.

-Subject: [PATCH 1/2] armv7: add mmio timer
+Subject: [PATCH] armv7: adding generic timer access through MMIO
 
-This timer can be used by u-boot when arch-timer is not available in
-core, for example, Cortex-A5.
+This driver enables the ARMv7 generic timer.
+
+The access to the timer registers is through memory mapping (MMIO).
+
+This driver can be used by u-boot to access to the timer through MMIO
+when arch_timer is not available in the core (access using system
+instructions not possible), for example, in case of Cortex-A5.
+
+This driver configures and enables the generic timer at
+the u-boot initcall level (timer_init) before u-boot relocation.
