* kallsyms: remove usage of memmem and _GNU_SOURCE from scripts/kallsyms.cPaulo Marques2007-07-17
| | | | | | | | | | | | The only in-kernel user of "memmem" is scripts/kallsyms.c and it only uses it to find tokens that are 2 bytes in size. It is trivial to replace it with a simple function that finds 2-byte tokens. This should help users from systems that don't have the memmem GNU extension available.

* kbuild: use -fno-optimize-sibling-calls unconditionallyAdrian Bunk2007-07-17

* kconfig: reset generated values only if Kconfig and .config agree.Roman Zippel2007-07-17
| | | | | | | | | | | | | | | | | | | | Normally generated values (Kconfig entries without a prompt) are cleared as they are regenerated anyway and so they appear as new should they become visible and defaults work as expected (once a value is set defaults aren't used anymore). The detection whether a value is generated or not is only based on its visibility status, which can quickly change for a lot of symbols by just removing a single line from .config or adding a dependency to Kconfig as you noticed. The patch now suppresses this logic when .config and Kconfig aren't in sync and .config needs to be updated, so that you can remove now a random value from .config and oldconfig won't reask for many other values.

| | | | | | | | | | | | | Modify the ncurses configuration tool ('make menuconfig') in a way that the user can enter the search string (/) both with or without the leading 'CONFIG_'.

* kbuild: use POSIX BRE in headers install targetMike Frysinger2007-07-17
| | | | | | | | | | | | | | | The sed expression used at the moment in scripts/Makefile.headersinst relies on the (handy) GNU extension where you can escape ERE's in an otherwise BRE without using the GNU -r option. The following patch replaces this "\+" usage with a functionally equivalent POSIX BRE compliant "\{1,\}". Tested with `make headers_install` against blackfin/x86_64/i386 targets.

* Whitelist references from __dbe_table to .initRalf Baechle2007-07-17
| | | | | | | | | | | | | | | This is needed on MIPS where the same mechanism as get_user() is used to intercept bus error exceptions for some hardware probes. Without this patch modpost will throw spurious warnings: LD vmlinux SYSMAP System.map SYSMAP .tmp_System.map MODPOST vmlinux WARNING: arch/mips/sgi-ip22/built-in.o(__dbe_table+0x0): Section mismatch: reference to .init.text: Signed-off-by: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
* modpost white list pattern adjustmentJan Beulich2007-07-17
| | | | | | | | | | gcc puts data into .data.rel or .data.rel.* on some architectures (e.g. ia64) or under certain conditions, so whatever is legal relative to .data should also be legal for those other sections.

* kbuild: do section mismatch check on full vmlinuxSam Ravnborg2007-07-17
| | | | | | | | | | | | | | | Previously we did do the check on the .o files used to link vmlinux but that failed to find questionable references across the .o files. Create a dedicated vmlinux.o file used only for section mismatch checks that uses the defualt linker script so section does not get renamed. The vmlinux.o may later be used as part of the the final link of vmlinux but for now it is used fo section mismatch only. For a defconfig build this is instant but for an allyesconfig this add two minutes to a full build (that anyways takes ~2 hours). Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
* kbuild: whitelist references from variables named _timer to .init.textSam Ravnborg2007-07-16
| | | | | | | | | arm uses a lot of ops structures named *_timer that has legitimite references to .init.text. So let's add this variable to the list of variables that may reference .init.text without causing any warning. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
* kbuild: remove hardcoded _logo names from modpostSam Ravnborg2007-07-16

| | | | | | | | | | | | | | | | | | | | | | | Massimo Maiurana <maiurana@gmail.com> reported that update-po-config was broken: 1) spelling errors in Makefile so arch/um failed 2) UTF-8 was not supported The following patch address the above problems. kxgettext now append the output to the .pot file generated by xgettext - so we have a header. In all places UFT-8 is specifed so we now flawlessly support UTF-8. The Kconfig files had an empty string in a few cases - these are now supressed in kxgettext. With this the translators can now pick up where they left and get it all translated. There are ~11000 strings to be translated...

* kbuild: add support for squashing uid/gid in gen_initramfs_list.shMike Frysinger2007-07-16
| | | | | | | | | | | Sometimes it is useful to squash all uid's/gid's to 0:0 regardless of current owner. For example, in build systems that get run as arbitrary users (uClinux-dist). This adds a special "squash" keyword so you can do '-g squash -u squash' and have ownership squashed to root.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We re-use the RESVSP/UNRESVSP ioctls from xfs which allow the user to allocate and deallocate regions to a file without zeroing data or changing i_size. Though renamed, the structure passed in from user is identical to struct xfs_flock64. The three fields that are actually used right now are l_whence, l_start and l_len. This should get ocfs2 immediate compatibility with userspace software using the pre-existing xfs ioctls. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Provide an internal interface for the removal of arbitrary file regions. ocfs2_remove_inode_range() takes a byte range within a file and will remove existing extents within that range.

| * | ocfs2: update truncate handling of partial clustersMark Fasheh2007-07-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | The partial cluster zeroing code used during truncate usually assumes that the rightmost byte in the range to be zeroed lies on a cluster boundary. This makes sense for truncate, but punching holes might require zeroing on non-aligned rightmost boundaries. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | Add code to the btree paths to support the removal of arbitrary regions within an existing extent.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This can now be trivially supported with re-use of our existing extend code. ocfs2_allocate_unwritten_extents() takes a start offset and a byte length and iterates over the inode, adding extents (marked as unwritten) until len is reached.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Update the write code to detect when the user is asking to write to an unwritten extent.
