Subject: include/linux/kexec.h: silence compile warnings
Patch series "kexec_file: Clean up purgatory load", v2.
Following the discussion with Dave and AKASHI, here are the common code
patches extracted from my recent patch set (Add kexec_file_load support to
s390) [1]. The patches were extracted to allow upstream integration
together with AKASHI's common code patches before the arch code gets
adjusted to the new base.
The reason for this series is to prepare common code for adding
kexec_file_load to s390 as well as cleaning up the mis-use of the
sh_offset field during purgatory load. In detail this series contains:
Patch #1&2: Minor cleanups/fixes.
Patch #3-9: Clean up the purgatory load/relocation code. Especially
remove the mis-use of the purgatory_info->sechdrs->sh_offset field,
currently holding a pointer into either kexec_purgatory (ro) or
purgatory_buf (rw) depending on the section. With these patches the
section address will be calculated verbosely and sh_offset will contain
the offset of the section in the stripped purgatory binary
(purgatory_buf).
Patch #10: Allows architectures to set the purgatory load address. This
patch is important for s390 as the kernel and purgatory have to be loaded
to fixed addresses. In current code this is impossible as the purgatory
load is opaque to the architecture.
Patch #11: Moves x86 purgatories sha implementation to common lib/
directory to allow reuse in other architectures.
This patch (of 11)
When building the kernel with CONFIG_KEXEC_FILE enabled gcc prints a
compile warning multiple times.
In file included from <path>/linux/init/initramfs.c:526:0:
<path>/include/linux/kexec.h:120:9: warning: `struct kimage' declared inside parameter list [enabled by default]
unsigned long cmdline_len);
^
This is because the typedefs for kexec_file_load uses struct kimage before
it is declared. Fix this by simply forward declaring struct kimage.
