When typeahead find is enabled, using 'y', 'n' and 'm' to change the status
of the configuration items will also start up the search system, making you
jump around the configuration.Disabling the enable_search property does not mean that search is not
possible, it only disables the typeahead; to execute a search in the
treeview, you can just call it up explicitly (i.e.: on most systems that
will be Ctrl-f).Signed-off-by: Diego Elio 'Flameeyes' Pettenò

The arch/*/boot/Makefile use cc-options to check for GCC command options
and cc-options use the hardened specs when checking for GCC command
options. When -fPIE is pass to cc1 it can't use -ffreestanding or
-fno-toplevel-reorder. Then it fail to build stuff with -ffreestanding
and -fno-toplevel-reorder.Thanks to Fredric Johansson for finding the main problem behind a failed
build using a hardened toolchain.Signed-off-by: Magnus Granberg

The tag file generated by the tags.sh script has some issue.
First:
The identifier-list miss the
DEFINE_TRACE,EXPORT_TRACEPOINT_SYMBOL,EXPORT_TRACEPOINT_SYMBOL_GPL
special handling, which can result in a wrong tag, not to jump to the
right variable definition or function implementation.Second:
It makes no real sense to include function prototypes and external and
forward variable declarations, because jumping to a tag will sometimes
go to this and not to the real definition and implementation. The information
about the declaration is still there at the definition and implementation
place.So this patch make it lot easier to navigate through the kernel source
tree using vi.Signed-off-by: Stefani Seibold

Sometimes when configuring need to disable some unused item, but the item is
selected by many other items, it's hard to find the real dependency which
selected it, This patch add every symbol's value accompanied to make it
possible to find the real dependency easily.An example is CONFIG_RFKILL,
---------------------- RF switch subsystem support ----------------------
| CONFIG_RFKILL: |
| |
| Say Y here if you want to have control over RF switches |
| found on many WiFi and Bluetooth cards. |
| |
| To compile this driver as a module, choose M here: the |
| module will be called rfkill. |
| |
| Symbol: RFKILL [=m] |
| Prompt: RF switch subsystem support |
| Defined at net/rfkill/Kconfig:4 |
| Depends on: NET [=y] |
| Location: |
| -> Networking support (NET [=y]) |
| Selected by: IWLCORE [=n] && NETDEVICES [=y] && !S390 [=S390] && PC |

When building a kernel for a different architecture
kbuild requires the user always to specify ARCH and
CROSS_COMPILE on the command-line.We use the asm symlink to detect if user forgets to
specify the correct ARCH value - but that symlink
is about to die. And we do now want to loose this check.This patch save the settings of ARCH and CROSS_COMPILE
in two files named:include/generated/kernel.arch
include/generated/kernel.crossThe settings are saved during "make *config" time
and always read.If user try to change the settings we error out.
This works both for plain builds and for O=...
builds.So now you can do:
$ mkdir sparc64
$ make O=sparc64 ARCH=sparc64 CROSS_COMPILE=sparc64-linux- defconfig
$ cd sparc64
$ makeNotice that you no longer need to tell kbuild
the settings of ARCH and CROSS_COMPILE when you type make
in the output directory.Likewise for plain builds where you do not use O=...
Signed-off-by: Sam Ravnborg
Cc: Roland McGrath -
Replace the use of CROSS_COMPILE to select a customized
installkernel script with the possibility to set INSTALLKERNEL
to select a custom installkernel script when running make:make INSTALLKERNEL=arm-installkernel install
With this patch we are now more consistent across
different architectures - they did not all support use
of CROSS_COMPILE.The use of CROSS_COMPILE was a hack as this really belongs
to gcc/binutils and the installkernel script does not change
just because we change toolchain.The use of CROSS_COMPILE caused troubles with an upcoming patch
that saves CROSS_COMPILE when a kernel is built - it would no
longer be installable.
[Thanks to Peter Z. for this hint]This patch undos what Ian did in commit:

This is largely a straightforward conversion. The patch results in
fewer output sections, and some data being reordered, but should have
no functional impact.Also, note that this patch moves some data (namely, init_task and
cacheline-aligned) inside [_sdata,_edata].Because frv already builds using -ffunction-sections -fdata-sections,
we can't use BSS_SECTION or RW_DATA_SECTION yet, since they do not
currently include the required .bss.* and .data.* sections.Signed-off-by: Nelson Elhage
