Subject: Fix building on x86_64 with binutils 2.41
Git-commit: 328de8e00e298f00d7ba6b25dc3950147e9642e6
Patch-mainline:
References:
Acked-by: Jiri Bohac <jbohac@suse.cz>
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:

From: Jiri Bohac <jbohac@suse.cz>
Subject: [PATCH] kexec: dont use kexec_file_load on XEN
Patch-mainline: 94fbe64fb22d61726ca0c0996987574b6c783c19
References: bsc#1218590
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).

From: Petr Tesarik <ptesarik@suse.com>
Subject: riscv: fix build with hotplug support
Upstream: not yet, blocked by base RISC-V patches
Commit 3c47f384f1c4 ("kexec_load: Use new kexec flag for hotplug support")
adds a new architecture-specific function named arch_do_exclude_segment.
Since RISC-V does not yet implement hotplug updates in the kernel, add a
trivial definition of this function to kexec-tools.
