* coredump: default CONFIG_CORE_DUMP_DEFAULT_ELF_HEADERS=yRoland McGrath2010-10-271-2/+2
| | | | | | | | | | | | | | | The userland ELF tools have been coping with partial-segments core files for a few years now. Multiple distro builds are now setting this option. It behooves everyone who ever deals with core files to have more info dumped in there, especially as more and more people's compilers are producing build IDs. Make it the default. Anyone using older tools confused by these core files can configure this option off, or just change /proc/PID/coredump_filter after boot.

* add CONFIG_CORE_DUMP_DEFAULT_ELF_HEADERSRoland McGrath2008-10-201-0/+22
| | | | | | | | | | | | | | | | | | | | This adds a kconfig option to change the /proc/PID/coredump_filter default. Fedora has been carrying a trivial patch to change the hard-wired value for this default, since Fedora 8. The default default can't change safely because there are old GDB versions out there (all before 6.7) that are confused by the core dump files created by the MMF_DUMP_ELF_HEADERS setting.

* Introduce HAVE_AOUT symbol to remove hard-coded arch list for BINFMT_AOUTDavid Woodhouse2008-09-061-1/+4
| | | | | | | | | | | HAVE_AOUT doesn't quite do the same thing as the recently removed ARCH_SUPPORTS_AOUT config option. That was set even on platforms where binfmt_aout isn't supported, although it's not entirely clear why. So it's best just to introduce a new symbol, handled consistently with other similar HAVE_xxx symbols; with a simple 'select' in the arch Kconfig.

* make BINFMT_FLAT a boolAdrian Bunk2008-04-291-1/+1
| | | | | | | | | | | | | I have not yet seen anyone saying he has a reasonable use case for using BINFMT_FLAT modular on his embedded device. Considering that fs/binfmt_flat.c even lacks a MODULE_LICENSE() I really doubt there is any, and this patch therefore makes BINFMT_FLAT a bool.

* aout: suppress A.OUT library support if !CONFIG_ARCH_SUPPORTS_AOUTDavid Howells2008-02-081-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Suppress A.OUT library support if CONFIG_ARCH_SUPPORTS_AOUT is not set. Not all architectures support the A.OUT binfmt, so the ELF binfmt should not be permitted to go looking for A.OUT libraries to load in such a case. Not only that, but under such conditions A.OUT core dumps are not produced either. To make this work, this patch also does the following: (1) Makes the existence of the contents of linux/a.out.h contingent on CONFIG_ARCH_SUPPORTS_AOUT. (2) Renames dump_thread() to aout_dump_thread() as it's only called by A.OUT core dumping code. (3) Moves aout_dump_thread() into asm/a.out-core.h and makes it inline. This is then included only where needed. This means that this bit of arch code will be stored in the appropriate A.OUT binfmt module rather than the core kernel. (4) Drops A.OUT support for Blackfin (according to Mike Frysinger it's not needed) and FRV. This patch depends on the previous patch to move STACK_TOP[_MAX] out of asm/a.out.h and into asm/processor.h as they're required whether or not A.OUT format is available.

* blackfin architectureBryan Wu2007-05-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for the Analog Devices Blackfin processor architecture, and currently supports the BF533, BF532, BF531, BF537, BF536, BF534, and BF561 (Dual Core) devices, with a variety of development platforms including those avaliable from Analog Devices (BF533-EZKit, BF533-STAMP, BF537-STAMP, BF561-EZKIT), and Bluetechnix! Tinyboards. The Blackfin architecture was jointly developed by Intel and Analog Devices Inc. (ADI) as the Micro Signal Architecture (MSA) core and introduced it in December of 2000. Since then ADI has put this core into its Blackfin processor family of devices. The Blackfin core has the advantages of a clean, orthogonal,RISC-like microprocessor instruction set. It combines a dual-MAC (Multiply/Accumulate), state-of-the-art signal processing engine and single-instruction, multiple-data (SIMD) multimedia capabilities into a single instruction-set architecture. The Blackfin architecture, including the instruction set, is described by the ADSP-BF53x/BF56x Blackfin Processor Programming Reference http://blackfin.uclinux.org/gf/download/frsrelease/29/2549/Blackfin_PRM.pdf The Blackfin processor is already supported by major releases of gcc, and there are binary and source rpms/tarballs for many architectures at: http://blackfin.uclinux.org/gf/project/toolchain/frs There is complete documentation, including "getting started" guides available at: http://docs.blackfin.uclinux.org/ which provides links to the sources and patches you will need in order to set up a cross-compiling environment for bfin-linux-uclibc This patch, as well as the other patches (toolchain, distribution, uClibc) are actively supported by Analog Devices Inc, at: http://blackfin.uclinux.org/ We have tested this on LTP, and our test plan (including pass/fails) can be found at: http://docs.blackfin.uclinux.org/doku.php?id=testing_the_linux_kernel [m.kozlowski@tuxland.pl: balance parenthesis in blackfin header files] Signed-off-by: Bryan Wu <bryan.wu@analog.com> Signed-off-by: Mariusz Kozlowski <m.kozlowski@tuxland.pl> Signed-off-by: Aubrey Li <aubrey.li@analog.com> Signed-off-by: Jie Zhang <jie.zhang@analog.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* Linux-2.6.12-rc2Linus Torvalds2005-04-161-0/+134
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
