+Subject: [PATCH 2/2] Fix building on x86_64 with binutils 2.41
+
+Newer versions of the GNU assembler (observed with binutils 2.41) will
+complain about the ".arch i386" in files assembled with "as --64",
+with the message "Error: 64bit mode not supported on 'i386'".
+
+Fix by moving ".arch i386" below the relevant ".code32" directive, so
+that the assembler is no longer expecting 64-bit instructions to be used
+by the time that the ".arch i386" directive is encountered.
+
+Based on similar iPXE fix:

+Subject: [PATCH 1/2] kexec: don't use kexec_file_load on XEN
+
+Since commit 29fe5067ed07 ("kexec: make -a the default")
+kexec tries the kexec_file_load syscall first and only falls back to kexec_load on
+selected error codes.
+
+This effectively breaks kexec on XEN, unless -c is pecified to force the kexec_load
+syscall.
+
+The XEN-specific functions (xen_kexec_load / xen_kexec_unload) are only called
+from my_load / k_unload, i.e. the kexec_load code path.
+
+With -p (panic kernel) kexec_file_load on XEN fails with -EADDRNOTAVAIL (crash
+kernel reservation is ignored by the kernel on XEN), which is not in the list
+of return codes that cause the fallback to kexec_file.
+
+Without -p kexec_file_load actualy leads to a kernel oops on v6.4.0
+(needs to be dubugged separately).
