Joe Lawrence 51a0b7c4ed livepatch/klp-build: report patch validation fuzz
Capture the output of the patch command to detect when a patch applies
with fuzz or line offsets.

If such "fuzz" is detected during the validation phase, warn the user
and display the details.  This helps identify input patches that may
need refreshing against the target source tree.

Ensure that internal patch operations (such as those in refresh_patch or
during the final build phase) can still run quietly.

Josh Poimboeuf 6f93f7b068 livepatch/klp-build: Fix inconsistent kernel version
If .config hasn't been synced with auto.conf, any recent changes to
CONFIG_LOCALVERSION* may not get reflected in the kernel version name.

Use "make syncconfig" to force them to sync, and "make -s kernelrelease"
to get the version instead of having to construct it manually.

Update SHORT_CIRCUIT behavior to better handle patch validation and
argument processing in later klp-build steps.

Perform patch validation for both step 1 (building original kernel) and
step 2 (building patched kernel) to ensure patches are verified before
any compilation occurs.

Additionally, allow the user to omit input patches when skipping past
step 2.

Joe Lawrence d36a7343f4 livepatch/klp-build: switch to GNU patch and recountdiff
The klp-build script is currently very strict with input patches,
requiring them to apply cleanly via `git apply --recount`.  This
prevents the use of patches with minor contextual fuzz relative to the
target kernel sources.

To allow users to reuse a patch across similar kernel streams, switch to
using GNU patch and patchutils for intermediate patch manipulation.
Update the logic for applying, reverting, and regenerating patches:

- Use 'patch -p1' for better handling of context fuzz.
- Use 'recountdiff' to update line counts after FIX_PATCH_LINES.
- Drop git_refresh() and related git-specific logic.

Joe Lawrence 757bd10ff0 livepatch/klp-build: support patches that add/remove files
The klp-build script prepares a clean patch by populating two temporary
directories ('a' and 'b') with source files and diffing the result.
However, this process fails when a patch introduces a new source file,
as the script attempts to copy files that do not yet exist in the
original source tree.  Likewise, it fails when a patch removes a source
file and the script attempts to copy a file that no longer exists.

Refactor the file-gathering logic to distinguish between original input
files and patched output files:

- Split get_patch_files() into get_patch_input_files() and
  get_patch_output_files() to identify which files exist before and
  after patch application.
- Filter out "/dev/null" from both to handle file creation/deletion.
- Update refresh_patch() to only copy existing input files to the 'a'
  directory and the resulting output files to the 'b' directory.

Nathan Chancellor ec4c28276c kbuild: Consolidate C dialect options
Introduce CC_FLAGS_DIALECT to make it easier to update the various
places in the tree that rely on the GNU C standard and Microsoft
extensions flags atomically. All remaining uses of '-std=gnu11' and
'-fms-extensions' are in the tools directory (which has its own build
system) and other standalone Makefiles. This will allow the kernel to
use a narrower option to enable the Microsoft anonymous tagged structure
extension in a simpler manner. Place the CC_FLAGS_DIALECT block after
the configuration include (so that a future change can move the
selection of the flag to Kconfig) but before the
arch/$(SRCARCH)/Makefile include (so that CC_FLAGS_DIALECT is available
for use in those Makefiles).
