CI: pin to kas 3.2 as 3.2.1 fails

For some reason the kas 3.2.1 container fails:

No such file or directory: '/builds/engineering/yocto/meta-arm/ci/ci/base.yml'

Note the repeated /ci/, which is wrong.

Pin the kas container to 3.2 for now until this is resolved.

+# Docker Extern Containers
+#
+# This class allows docker image tarballs to be installed in the rootfs
+#
+# The images can be selected using the variable CONTAINER_IMAGE_FILES which
+# should contain a space seperated list of absolute paths or yocto urls for
+# docker images that have been exported using docker export:
+# - https://docs.docker.com/engine/reference/commandline/export/
+#
+# src_uri_parse_var.bbclass is used to parse CONTAINER_IMAGE_FILES
+#
+# There are 4 supported formats for CONTAINER_IMAGE_FILES entries:
+#
+# - http/https url
+#   - CONTAINER_IMAGE_FILES = "https://[url]:[port]/alpine.tar;md5sum=..."
+#
+# - file:// absolute local path from root
+#   - CONTAINER_IMAGE_FILES = "file:///containers/alpine2.tar"
+#
+# - file:// path relative to FILESEXTRAPATHS
+#   - CONTAINER_IMAGE_FILES = "file://foo/alpine3.tar"
+#     FILESEXTRAPATHS .= "/containers:"
+#
+# - plain absolute local path from root
+#   - CONTAINER_IMAGE_FILES = "/containers/foo/bar/alpine4.tar"
+#
+# It is not recommended to use other yocto URL types, as they may result in
+# undefined behaviour.
+#
+# A semicolon seperated list of install arguments can follow each image path:
+# - conname : the name that will be attached when the image is imported
+#             (default: [filename, without extension])
+# - contag  : the tag that will be attached when the image is imported
+#             (default: local)
+# - conkeep : Flag for whether the exported container image file should be
+#             kept once the import has been completed
+#             (default: 0)
+#
+# Any other arguments, for example an md5sum, will be assumed to be fetch
+# arguments, and will be kept when the path is added to the SRC_URI
+#
+# e.g.  CONTAINER_IMAGE_FILES = "\
+# https://[url]:[port]/alpine.tar;md5sum=[checksum];conkeep=1 \
+# file:///containers/alpine2.tar;contag=latest;conname=docker2 \

-Subject: [PATCH] xen: use handle_fasteoi_irq to handle xen dynamic events
-
-When handling Xen events, we need to make sure the following sequence is
-followed:
-
-- 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.
