Make conf_write_symbol() grammar agnostic to be able to use it from different
code path. These path pass a printer callback which will print a symbol's name
and its value in different format.conf_write_symbol()'s job become mostly only to prepare a string for the
printer. This avoid to have to pass specialized flag to generic

This is an attempt to simplify the expressing printed by kconfig when a
symbol is selected but still has direct unmet dependency.First, the symbol reverse dependency is split in sub-expression. Then,
each sub-expression is checked to ensure that it does not contains the
unmet dependency. This removes the false-positive symbols and fixed symbol
which already have the correct dependency. Finally, only the symbol
responsible of the "select" is printed, instead of its full dependency tree.CC: Catalin Marinas

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. Given that we are close to the release now, disable the

select PERF_EVENTS if HAVE_HW_BREAKPOINTconfig PERF_EVENTS

savedefconfig will save a minimal config to a file
named "defconfig".The config symbols are saved in the same order as
they appear in the menu structure so it should
be possible to map them to the relevant menus
if desired.The implementation was tested against several minimal
configs for arm which was created using brute-force.There was one regression related to default numbers
which had their valid range further limited by another symbol.Sample:
config FOO
int "foo"
default 4config BAR
int "bar"
range 0 FOOIf FOO is set to 3 then BAR cannot take a value higher than 3.
But the current implementation will set BAR equal to 4.This is seldomly used and the final configuration is OK,
and the fix was non-trivial.
So it was documented in the code and left as is.Signed-off-by: Sam Ravnborg

Consider following kconfig file:
config TEST1
bool "test 1"
depends on TEST2config TEST2
bool "test 2"
depends on TEST1Previously kconfig would report:
foo:6:error: found recursive dependency: TEST2 -> TEST1 -> TEST2
With the following patch kconfig reports:
foo:5:error: recursive dependency detected!
foo:5: symbol TEST2 depends on TEST1
foo:1: symbol TEST1 depends on TEST2Note that we now report where the offending symbols are defined.
This can be a great help for complex situations involving
several files.Patch is originally from Roman Zippel with a few adjustments by Sam.

The "select" statement in Kconfig files allows the enabling of options
even if they have unmet direct dependencies (i.e. "depends on" expands
to "no"). Currently, the "depends on" clauses are used in calculating
the visibility but they do not affect the reverse dependencies in any
way.The patch introduces additional tracking of the "depends on" statements
and prints a warning on selecting an option if its direct dependencies
are not met.Signed-off-by: Catalin Marinas

A symbol's value won't be recalc-ed until we save config file or
enter the menu where the symbol sits.So If I enable OPTIMIZE_FOR_SIZE, and search FUNCTION_GRAPH_TRACER:
Symbol: FUNCTION_GRAPH_TRACER [=y]
Prompt: Kernel Function Graph Tracer
Defined at kernel/trace/Kconfig:140
Depends on: ... [=y] && (!X86_32 [=y] || !CC_OPTIMIZE_FOR_SIZE [=y])
...From the dependency it should result in FUNCTION_GRAPH_TRACER=n,
but it still shows FUNCTION_GRAPH_TRACER=y.Signed-off-by: Li Zefan

While looking for something else I noticed that the symbol
hash function used by kconfig is quite poor. It doesn't
use any of the standard hash techniques but simply
adds up the string and then uses power of two masking,
which is both known to perform poorly.The current x86 kconfig has over 7000 symbols.
When I instrumented it showed that the minimum hash chain
length was 16 and a significant number of them was over
30.It didn't help that the hash table size was only 256 buckets.
This patch increases the hash table size to a larger prime
and switches to a FNV32 hash. I played around with a couple of hash
functions, but that one seemed to perform best with reasonable
hash table sizes.Increasing the hash table size even further didn't
seem like a good idea, because there are a couple of global
walks which walk the complete hash table.I also moved the unnamed bucket to 0. It's still the longest
of all the buckets (44 entries), but hopefully it's not
often hit except for the global walk which doesn't care.The result is a much nicer distribution:
(first column bucket length, second number of buckets with that length)1: 3505
2: 1236
3: 294
4: 52
5: 3
47: 1

As choice dependency are now fully checked, it's quite easy to add support
for named choices. This lifts the restriction that a choice value can only
appear once, although it still has to be within the same group,
but multiple choices can be joined by giving them a name.
While at it I cleaned up a little the choice type logic to simplify it a

that SERIO is selected to m, but SERIO_I8042 isn't selected so the default
of y is used instead.
We already had the problem in the past that select and default don't work
well together, so this patch cleans this up and makes the rule hopefully
more straightforward. Basically now the value is calculated like this:(value && dependency) || select
where the value is the user choice (if available and the symbol is
visible) or default.In this case it means SERIO and SERIO_I8042 are both set to y due to their
default and if SERIO didn't had the default, then the SERIO_I8042 value
would be limited to m due to the dependency.I tested this patch with more 10000 random configs and above case is the
only the difference that showed up, so I hope there is nothing that
depended on the old more complex and subtle rules.Signed-off-by: Roman Zippel

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.Signed-off-by: David Gibson

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.Let it rip!
