| | | | | | | | | | | | | | | | | This is a first version of an interactive mode for scripts/get_maintainer.pl. It allows the user to interact with the script. Each cc candidate can be selected and deselected and a shortlog of authored commits can be displayed for each candidate. The menu is displayed via STDERR, the end result is outputted to STDOUT.

* scripts/get_maintainer.pl: add default --git-fallback, remove default --gitJoe Perches2010-10-261-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adding commit signers when there is a listed MAINTAINER for a file can make the output list longer than necessary. Change the --git default from on to off. Add a new --git-fallback option (default on) used to add commit signers only when there is no MAINTAINER for a file. git history is used when --git-fallback is enabled and the pattern directory depth is not the same as the file directory depth. For instance: X86 ARCHITECTURE (32-BIT AND 64-BIT) M: Thomas Gleixner <tglx@linutronix.de> M: Ingo Molnar <mingo@redhat.com> M: "H.

The build process has a special file: scripts/mod/empty.o. This is built from empty.c which is literally an empty file (except for a single comment). This file is used to find information about the target elf format, like endianness and word size. The problem comes up when we need to build recordmcount. The build process requires that empty.o is built first. The build rules for empty.o will try to execute recordmcount on the empty.o file. We get an error that recordmcount does not exist. To avoid this recursion, the build file will skip running recordmcount if the file that it is building is script/mod/empty.o.

But because it references mcount(), the mcount() address is placed in the relocation table. The C version of recordmcount reads the relocation table of all object files, and it will add all references to mcount to the __mcount_loc table that is used to find the places that call mcount() and change the call to a nop. When recordmcount finds the mcount reference in kernel/trace/ftrace.o, it saves that location even though the code is not a call, but references mcount as data. On boot up, when all calls are converted to nops, the code has a safety check to determine what op code it is actually replacing before it replaces it. If that op code at the address does not match, then a warning is printed and the function tracer is disabled. The reference to mcount in ftrace.c, causes this warning to trigger, since the reference is not a call to mcount(). The ftrace.c file is not compiled with the -pg flag, so no calls to mcount() should be expected. This patch simply makes recordmcount.c skip the kernel/trace/ftrace.c file. This was the same solution used by the perl version of recordmcount.

This was due to the need of using the 32 and 64 bit elf structures. This patch consolidates the two by using macros to define the 32 and 64 bit names in a recordmcount.h file, and then by just defining a RECORD_MCOUNT_64 macro and including recordmcount.h twice we create the funtions for both the 32 bit version as well as the 64 bit version using one code source.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 861b4ea4 broke oldnoconfig when removed the oldnoconfig checks on if (input_mode == nonint_oldconfig || input_mode == oldnoconfig) { if (input_mode == nonint_oldconfig && sym->name && !sym_is_choice_value(sym)) { to avoid oldnoconfig chugging through the else stanza. Fix that to restore expected behaviour (which I've confirmed in the Fedora kernel build that the configs end up looking the same.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | After fixing a use-after-free bug in kconfig, a 'make defconfig' or 'make allmodconfig' fills the screen with warnings that were not detected before.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When you don't use !E or !I but only !F, then it's very easy to miss including some functions, structs etc. in documentation. To help finding which ones were missed, allow printing out the unused ones as warnings. For example, using this on mac80211 yields a lot of warnings like this: Warning: didn't use docs for DOC: mac80211 workqueue Warning: didn't use docs for ieee80211_max_queues Warning: didn't use docs for ieee80211_bss_change Warning: didn't use docs for ieee80211_bss_conf when generating the documentation for it.

One would think > setting LOCALVERSION_AUTO to false would do it, but no such luck... Fix this by checking if the kernel source tree is the root of the git or hg repository. No fix for svn: If the kernel source is not tracked in the svn repository, it works as expected, otherwise determining the 'repository root' is not really a defined task.

Consider following minimal configuration: $cat Kconfig choice prompt "choice" optional config A bool "a" config B bool "b" endchoice $cat .config | grep -v ^# CONFIG_A=y $conf --savedefconfig=defconfig Kconfig would before this fix result in an empty file, because kconfig would assume that CONFIG_A=y is a default value. But because the choice is optional the default is that both A and B are =n. Fix so we handle optional choices correct.

Consider following example: config M def_bool y option modules choice prompt "choice list" config A tristate "a" config B tristate "b" endchoice With a defconfig like this: CONFIG_M=y CONFIG_A=y The resulting configuration would have CONFIG_A=m which was unexpected. The problem was not not all choice values were set and thus kconfig calculated a wrong value. The fix is to set all choice values when we read a defconfig files. conf_set_all_new_symbols() is refactored such that random choice values are now handled by a dedicated function. And new choice values are set by set_all_choice_values(). This was not the minimal fix, but the fix that resulted in the most readable code.
