2012-01-15kbuild: Fix compiler warning with assertion when calling 'fwrite'Arnaud Lacombe2-2/+5
Reinhard Tartler discovered a corner case of calling xfwrite() where the length of the string is zero. Arnaud Lacombe suggested to use assertion for the corner case, as fwrite(3) is currently used: 1) in comment printers. Empty comment are not allowed. 2) in a callback passed to expr_print(), where the string printed is either NULL OR non-empty. 3) in the lexer, auto-generated, and unused. I feel using assertion is a good solution: 1) It cleanly takes care of the above-mentioned corner case. 2) It can be easily disabled by defining NDEBUG. 3) It asserts xfwrite() is simply a wrapper for fwrite().

2012-01-15Kbuild: Use dtc's -d (dependency) optionStephen Warren1-1/+1
This hooks dtc into Kbuild's dependency system. Thus, for example, "make dtbs" will rebuild tegra-harmony.dtb if only tegra20.dtsi has changed yet tegra-harmony.dts has not. The previous lack of this feature recently caused me to have very confusing "git bisect" results. For ARM, it's obvious what to add to $(targets). I'm not familiar enough with other architectures to know what to add there. Powerpc appears to already add various .dtb files into $(targets), but the other archs may need something added to $(targets) to work.

Arnaud Lacombe pointed out the final checking that the requested configs were included in the final .config was broken. The example was that if you had a fragment that disabled CONFIG_DECOMPRESS_GZIP applied to a normal defconfig, there would be no final warning that CONFIG_DECOMPRESS_GZIP was acutally set in the final .config. This bug was introduced by me in v3 of the original patch, and the following patch reverts the invalid change.

2012-01-14kconfig: add merge_config.sh scriptjohn stultz1-0/+117
After noticing almost every distro has their own method of managing config fragments, I went looking at some best practices, and wanted to try to consolidate some of the different approaches so this fairly simple infrastructure can be shared (and new distros/build systems don't have to implement yet another config fragment merge script). This script is most influenced by the Windriver tools used in the Yocto Project, reusing some portions found there. This script merges multiple config fragments, warning on any overridden values. It then sets any unspecified values to their default, then finally checks to make sure no specified value was dropped due to unsatisfied dependencies. I'm sure this implementation won't work for everyone, and I expect it will need to evolve to adapt for various use cases. But I think its a reasonable starting point.

2012-01-13kconfig/streamline-config.pl: Fix parsing Makefile with variablesSteven Rostedt1-0/+29
Thomas Lange reported that when he did a 'make localmodconfig', his config was missing the brcmsmac driver, even though he had the module loaded. Looking into this, I found the file: drivers/net/wireless/brcm80211/brcmsmac/Makefile had the following in the Makefile: MODULEPFX := brcmsmac obj-$(CONFIG_BRCMSMAC) += $(MODULEPFX).o The way streamline-config.pl works, is parsing all the obj-$(CONFIG_FOO) += foo.o lines to find that CONFIG_FOO belongs to the module foo.ko. But in this case, the brcmsmac.o was not used, but a variable in its place. By changing streamline-config.pl to remember defined variables in Makefiles and substituting them when they are used in the obj-X lines, allows Thomas (and others) to have their brcmsmac module stay configured when it is loaded and running "make localmodconfig".

2012-01-06recordmcount: Fix handling of elf64 big-endian objects.David Daney1-1/+1
In ELF64, the sh_flags field is 64-bits wide. recordmcount was erroneously treating it as a 32-bit wide field. For little endian objects this works because the flags of interest (SHF_EXECINSTR) reside in the lower 32 bits of the word, and you get the same result with either a 32-bit or 64-bit read. Big endian objects on the other hand do not work at all with this error. The fix: Correctly treat sh_flags as 64-bits wide in elf64 objects. The symptom I observed was that my __start_mcount_loc..__stop_mcount_loc was empty even though ftrace function tracing was enabled.

2011-12-18kconfig: adapt update-po-config to new UML layoutPaul Bolle1-3/+2
Commit 5c48b108 ("um: take arch/um/sys-x86 to arch/x86/um") broke the make target update-po-config, as its symlink trick (again) fails. (Previous breakage was fixed with commit bdc69ca4 ("kconfig: change update-po-config to reflect new layout of arch/um").) The new UML layout allows to drop the symlick trick entirely. And if, one day, another architecture supports UML too, that should now work without again breaking this make target.

2011-11-22ARM: amba: Auto-generate AMBA driver module aliases during modpostDave Martin1-0/+72
This patch adds the necessary support in file2alias.c to define suitable aliases based on the amba_id table in AMBA driver modules. This should be sufficient to allow such modules to be auto-loaded via udev. The AMBA bus driver's uevent hotplug code is also modified to pass an approriate MODALIAS string in the event. For simplicity, the AMBA ID is treated an an opaque 32-bit numeber. Module alises use patterns as appropriate to describe the value- mask pairs described in the driver's amba_id list. The proposed alias format is (extended regex): ^amba:d(HEX){8}$ Where HEX is a single upper-case HEX digit or a pattern (? or [] expression) matching a single upper-case HEX digit, as expected by udev. "d" is short for "device", following existing alias naming conventions for other device types. This adds some flexibility for unambiguously extending the alias format in the future by adding additional leading and trailing fields, if this turns out to be necessary.

Add support for an "archheaders" target. This target can generate files that need to be installed for user space by "make headers_install" or "make headers_install_all". In order to support "make headers_install_all", it must be able to run without the tree having to be configured first.
