When doing its recursive dependency check, scripts/kconfig/conf uses the flag
SYMBOL_CHECK_DONE to avoid rechecking a symbol it has already checked.
However, that flag is only set at the top level, so if a symbol is first
encountered as a dependency of another symbol it will be rechecked every time
it is encountered until it's encountered at the top level.
This patch adjusts the flag setting so that each symbol will only be checked
once, regardless of whether it is first encountered at the top level, or while
recursing down from another symbol. On complex configurations, this vastly
speeds up scripts/kconfig/conf. The config in the powerpc merge tree is
particularly bad: this patch reduces the time for 'scripts/kconfig/conf -o
arch/powerpc/Kconfig' by a factor of 40 on a G5. That's even including the
time to print the config, so the speedup in the actual checking is more likely
2 or 3 orders of magnitude.

I made a patch that detects if libintl.h (needed for nls) is present on the

dummies for the used nls functions.
This way if there is nls support on the host system the *config targets
will build according to Arnaldo Carvalho de Melo's i18n modifications, else
it just uses the original English messages.

This patch changes the way the compression algorithm works. The base
algorithm is similiar to the previous but we force the compressed token
size to 2.
Having a fixed size compressed token allows for a lot of optimizations, and
that in turn allows this code to run over *all* the symbols faster than it
did before over just a subset.
Having it work over all the symbols will make it behave better when symbols
change positions between passes, and the "inconsistent kallsyms" messages
should become less frequent.
In my tests the compression ratio was degraded by about 0.5%, but the
results will depend greatly on the number of symbols to compress.

If CONFIG_AUTO_LOCALVERSION is set, the user is using a git-based tree, and the

kbuild failed to locate Makefile for external modules.
This brought to my attention how the variables for directories
have different values in different usage scenarios.
Different kbuild usage scenarios:
make - plain make in same directory where kernel source lives
make O= - kbuild is told to store output files in another directory
make M= - building an external module
make O= M= - building an external module with kernel output seperate from src
Value assigned to the different variables:
|$(src) |$(obj) |$(srctree) |$(objtree)
make |reldir to k src |as src |abs path to k src |abs path to k src
make O= |reldir to k src |as src |abs path to k src |abs path to output dir
make M= |abs path to src |as src |abs path to k src |abs path to k src
make O= M= |abs path to src |as src |abs path to k src |abs path to k output
path to kbuild file:
make | $(srctree)/$(src), $(src)
make O= | $(srctree)/$(src)
make M= | $(src)
make O= M= | $(src)
From the table above it can be seen that the only good way to find the
home directory of the kbuild file is to locate the one of the two variants
that is an absolute path. If $(src) is an absolute path (starts with /)
then use it, otherwise prefix $(src) with $(srctree).

Recently a change in the glibc elf.h header has been introduced causing

on sparc:

*** Warning: "" [net/sunrpc/auth_gss/auth_rpcgss.ko] undefined!
*** Warning: "" [net/sunrpc/auth_gss/auth_rpcgss.ko] undefined!

Ben Collins discovered that the STT_REGISTERED definition in glibc did change

-#define STT_REGISTER 13 /* Global register reserved to app. */
+#define STT_SPARC_REGISTER 13 /* Global register reserved to app. */
