When we had code like this in a header unifdef failed to deduct that the expression was always false - and we had code exported that was not intended for userspace. #if defined(__KERNEL__) && !defined(__ASSEMBLY__) int a; #endif This commit implment support in unidef which allows it to work out if an #if expression always evaluates true or false for symbols which are being undefined/always defined. The patch is slightly more complicated than I'd hoped because unifdef needs to see lines fully evaluated - doing otherwise causes it to mark the line as "dirty" and copy it over no matter what.

The STRIP_ASM_SYMS kconfig symbol mucks up the embedded menu because STRIP_ASM_SYMS is in the middle of the embedded menu items but it does not depend on EMBEDDED. Move it to beyond the end of the embedded menu so that the menu is presented correctly. Or if STRIP_ASM_SYMS should depend on EMBEDDED, that can also be fixed. Signed-off-by:

Correct the regular expression in scripts/headers_check.pl to include '_' as a valid character in the class; otherwise, the check will report a "leaked" symbol of CONFIG_A_B_C as merely CONFIG_A. This patch will make no difference whatsoever in the current kernel tree as the call to the perl routine that does that check is currently commented out: &check_include(); &check_asm_types(); &check_sizetypes(); &check_prototypes(); # Dropped for now. Too much noise &check_config(); However, I noticed that problem when I was building the yum downloadable kernel source rpm for fedora 11 (beta), which *does* run that check, and that's where the problem became obvious.

Regardless of KCONFIG_AUTOCONFIG, the filename written as a Make target into "include/config/auto.conf.cmd" was always the default one. Of course this doesn't make it work for the Kernel kbuild system, since there the filename is hardcoded at several places in the Makefiles. Signed-off-by:

Rather than hardcoding ".config" use conf_get_configname(), which also respects the environment variable KCONFIG_CONFIG. This fixes "make silentoldconfig" when KCONFIG_CONFIG is used and also suggests the given filename for "Load" and "Save as" in qconf. Signed-off-by:

All the KCONFIG_ environment variables were previously located in a section "Environment variables in 'menuconfig'", but neither are they restricted to 'menuconfig' nor are they all used by 'menuconfig'. Introduce the following three sections for these variables: * Environment variables for '*config' * Environment variables for '{allyes/allmod/allno/rand}config' * Environment variables for 'silentoldconfig' Furthermore this puts MENUCONFIG_MODE next to MENUCONFIG_COLOR into a common section "User interface options for 'menuconfig'".

The GNU make's origin function know undefined variable well, so the outer ifdef/endif conditional checking is unneeded. From `info make` documentation, origin will return `undefined' if VARIABLE was never defined. `command line' if VARIABLE was defined on the command line. ... Therefore, $(origin V) will get a value anyway, killing ifdef/endif is viable and safe. Furthermore, I've checked the minimal requirements from Documentation/Changes is GNU make 3.79.1, and that version of GNU make has support of origin function well already, so now it's safe to kill the outer conditional checking, without upgrading the minimal requirements.

The Debian packaging scripts created by the deb-pkg target do not pass on the standard Debian maintainer script parameters to hook scripts, which means that those scripts cannot tell whether they are being called during e.g. install vs. upgrade, or removal vs. purge of the package. As there are several variantions in how hook scripts are called from kernel packages, we pass the parameters in the environment variable DEB_MAINT_PARAMS rather than as extra arguments.

Our async work synchronization was broken by "async: make sure independent async domains can't accidentally entangle" (commit d5a877e8), because it would report the wrong lowest active async ID when there was both running and pending async work. This caused things like no being able to read the root filesystem, resulting in missing console devices and inability to run 'init', causing a boot-time panic. This fixes it by properly returning the lowest pending async ID: if there is any running async work, that will have a lower ID than any pending work, and we should _not_ look at the pending work list. There were alternative patches from Jaswinder and James, but this one also cleans up the code by removing the pointless 'ret' variable and the unnecesary testing for an empty list around 'for_each_entry()' (if the list is empty, the for_each_entry() thing just won't execute).
