2006-02-19kbuild: make cc-version available in kbuild filesSam Ravnborg
Move $(CC) support functions to Kbuild.include so they are available in the kbuild files. In addition the following was done: o as-option documented in Documentation/kbuild/makefiles.txt o Moved documentation to new section to match new scope of functions o added cc-ifversion used to conditionally select a text string dependent on actual $(CC) version o documented cc-ifversion o change so Kbuild.include is read before the kbuild file Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2006-02-19kbuild: check for section mismatch during modpost stageSam Ravnborg
Section mismatch is identified as references to .init* sections from non .init sections. And likewise references to .exit.* sections outside .exit sections. .init.* sections are discarded after a module is initialized and references to .init.* sections are oops candidates. .exit.* sections are discarded when a module is built-in and thus references to .exit are also oops candidates. The checks were possible to do using 'make buildcheck' which called the two perl scripts: reference_discarded.pl and reference_init.pl. This patch just moves the same functionality inside modpost and the scripts are then obsoleted. They will though be kept for a while so users can do double checks - but note that some .o files are skipped by the perl scripts so result is not 1:1. All credit for the concept goes to Keith Owens who implemented the original perl scrips - this patch just moves it to modpost. Compared to the perl script the implmentation in modpost will be run for each kernel build - thus catching the error much sooner, but the downside is that the individual .o file are not always identified.

2006-02-19kbuild: improved modversioning support for external modulesSam Ravnborg
With following patch a second option is enabled to obtain symbol information from a second external module when a external module is build. The recommended approach is to use a common kbuild file but that may be impractical in certain cases. With this patch one can copy over a Module.symvers from one external module to make symbols (and symbol versions) available for another external module.

2006-02-19kbuild: support building individual files for external modulesSam Ravnborg
Support building individual files when dealing with separate modules. So say you have a module named "foo" which consist of two .o files bar.o and fun.o. You can then do: make -C $KERNELSRC M=`pwd` bar.o make -C $KERNELSRC M=`pwd` bar.lst make -C $KERNELSRC M=`pwd` bar.i make -C $KERNELSRC M=`pwd` / <= will build all .o files and link foo.o make -C $KERNELSRC M=`pwd` foo.ko <= will build the module and do the modpost step to create foo.ko The above will also work if the external module is placed in a subdirectory using a hirachy of kbuild files.

2006-02-17[PATCH] ACPI: fix vendor resource length computationBjorn Helgaas
acpi_rs_get_list_length() needs to account for all the vendor-defined data bytes. Failing to include these causes buffers to be sized too small, which causes slab corruption when we later convert AML to resources and run off the end of the buffer. This causes slab corruption on machines that use ACPI vendor-defined resources. All HP ia64 machines do, and I'm told that some NEC machines may as well.

2006-02-17[PATCH] s390: smp initialization speedHeiko Carstens
The last changes that introduced the additional_cpus command line parameter also introduced a regression regarding smp initialization speed. In smp_setup_cpu_possible_map() cpu_present_map is set to the same value as cpu_possible_map. Especially that means that bits in the present map will be set for cpus that are not present. This will cause a slow down in the initial cpu_up() loop in smp_init() since trying to take cpus online that aren't present takes a while. Fix this by setting only bits for present cpus in cpu_present_map and set cpu_present_map to cpu_possible_map in smp_cpus_done().

If it is desired that additional cpus can be attached to the system the maximum number of additional cpus needs to be specified with this option. This change is necessary in order to limit the waste of per_cpu data structures.

2006-02-17[PATCH] Introduce CONFIG_DEFAULT_MIGRATION_COSTIngo Molnar
Heiko Carstens <heiko.carstens@de.ibm.com> wrote: The boot sequence on s390 sometimes takes ages and we spend a very long time (up to one or two minutes) in calibrate_migration_costs. The time spent there differs from boot to boot. Also the calculated costs differ a lot. I've seen differences by up to a factor of 15 (yes, factor not percent). Also I doubt that making these measurements make much sense on a completely virtualized architecture where you cannot tell how much cpu time you will get anyway. So introduce the CONFIG_DEFAULT_MIGRATION_COST method for an architecture to set the scheduler migration costs. This turns off automatic detection of migration costs. Makes sense on virtual platforms, where migration costs are hard to measure accurately.

2006-02-17[PATCH] fix deadlock in ext2Peter Staubach
Fix a deadlock possible in the ext2 file system implementation. This deadlock occurs when a file is removed from an ext2 file system which was mounted with the "sync" mount option. The problem is that ext2_xattr_delete_inode() was invoking the routine, sync_dirty_buffer(), using a buffer head which was previously locked via lock_buffer(). The first thing that sync_dirty_buffer() does is to lock the buffer head that it was passed. It does this via lock_buffer(). Oops. The solution is to unlock the buffer head in ext2_xattr_delete_inode() before invoking sync_dirty_buffer(). This makes the code in ext2_xattr_delete_inode() obey the same locking rules as all other callers of sync_dirty_buffer() in the ext2 file system implementation.
