"Paul Smith" reported that we would fail
to build with a new check that may be enabled in an
upcoming version of make.The error was:
Makefile:442: *** mixed implicit and normal rules. Stop.
The problem is that we did stuff like this:
config %config: ...
The solution was simple - the above was split into two with identical
prerequisites and commands.
With only three lines it was not worth to try to avoid the duplication.Cc: "Paul Smith"

kerneloops.org has been using an improved "decodecode" script,
specifically it has a special marker that shows which line in the assembly
the oops happened at, like this:20: 83 e0 03 and $0x3,%eax
23: 09 d8 or %ebx,%eax
25: 85 db test %ebx,%ebx
27: 89 02 mov %eax,(%edx)
29: 74 0f je 0x3a
2b:* 3b 73 04 cmp 0x4(%ebx),%esi

This adds an "override" keyword for use in *.symvers / *.symref files.
When a symbol is overridden, the symbol's old definition will be used for
computing checksums instead of the new one, preserving the previous
checksum. (Genksyms will still warn about the change.)This is meant to allow distributions to hide minor actual as well as fake
ABI changes. (For example, when extra type information becomes available
because additional headers are included, this may change checksums even
though none of the types used have actully changed.)This approach also allows to get rid of "#ifdef __GENKSYMS__" hacks in the
code, which are currently used in some vendor kernels to work around
checksum changes.Signed-off-by: Andreas Gruenbacher

Signed-off-by: Sam Ravnborg -
Sometimes it is preferable to avoid changes of exported symbol checksums
(to avoid breaking externally provided modules). When a checksum change
occurs, it can be hard to figure out what caused this change: underlying
types may have changed, or additional type information may simply have
become available at the point where a symbol is exported.Add a new --reference option to genksyms which allows it to report why
checksums change, based on the type information dumps it creates with the
--dump-types flag. Genksyms will read in such a dump from a previous run,
and report which symbols have changed (and why).The behavior can be controlled for an entire build as follows: If
KBUILD_SYMTYPES is set, genksyms uses --dump-types to produce *.symtypes
dump files. If any *.symref files exist, those will be used as the
reference to check against. If KBUILD_PRESERVE is set, checksum changes
will fail the build.Signed-off-by: Andreas Gruenbacher

as they do not benefit from the make functionality.
Moving the support to a shell script has several benefits:
- The readability of the code has increased a lot
- More people is able to extend the tags support
- We see less changes to the top-level MakefileThe shell script version includes improvements from:
Alexey Dobriyan (jump to kconfig symbols)
Alexey Dobriyan (drop ./ in paths)
Ian Campbell (simplified find algorithms)This version has a few caveats:
=> It does not support ALLSOURCE_ARCHS
- it is easy to add if it is really used
=> It assumes all archs have moved to arch/$ARCH/include
- until that happens we have a few additional hits in the archsSigned-off-by: Sam Ravnborg

Modify gen_init_cpio so that lines that specify files can contain
what looks like a shell variable that's expanded during processing.For example:
file /sbin/kinit ${RFS_BASE}/usr/src/klibc/kinit/kinit 0755 0 0
given RFS_BASE is "/some/directory" in the environment
would be expanded to
file /sbin/kinit /some/directory/usr/src/klibc/kinit/kinit 0755 0 0
If several environment variables appear in a line, they are all expanded
with processing happening from left to right.
Undefined variables expand to a null string.
Syntax errors stop processing, letting the existing error handling
show the user offending line.This patch helps embedded folks who frequently create several
RFS directories and then switch between them as they're tuning
an initramfs.Signed-off-by: gene.sally@timesys.com

There is a bunch of places in the build system where we do 'echo' to show

kbuild failed to expand include flags in KBUILD_CPPFLAGS
resulting in code like this in arch Makefiles:ifeq ($(KBUILD_SRC),)
KBUILD_CPPFLAGS += -Iinclude/foo

When adding extra -I options with O=... we could
end up in a situation where there were no parameters to -I.
So we had a commandline that looked like this:... -I -Wall ...
This had the undesired side effect that gcc assumed "-Wall"
was a path to look for include files so this options was
effectively ignored.This happens only when we build the generated module.mod.c files
as part of the final modules builds and is as such harmless
with current kbuild.
This bug was exposed when we rearranged the options to gcc.Signed-off-by: Sam Ravnborg

Count the insertion of new pages in the statistics used to drive the
pageout scanning code. This should help the kernel quickly evict
streaming file IO.We count on the fact that new file pages start on the inactive file LRU
and new anonymous pages start on the active anon list. This means
streaming file IO will increment the recent scanned file statistic, while
leaving the recent rotated file statistic alone, driving pageout scanning
to the file LRUs.Pageout activity does its own list manipulation.

Devices which share the same queue, like floppies and mtd devices, get
registered multiple times in the bdi interface, but bdi accounts only the
last registered device of the devices sharing one queue.On remove, all earlier registered devices leak, stay around in sysfs, and
cause "duplicate filename" errors if the devices are re-created.This prevents the creation of multiple bdi interfaces per queue, and the
bdi device will carry the dev_t name of the block device which is the
first one registered, of the pool of devices using the same queue.[akpm@linux-foundation.org: add a WARN_ON so we know which drivers are misbehaving]
