Allow macros that are annotated with kernel-doc to contain whitespace
between the '#' and "define". It's valid and being used, so allow it.Signed-off-by: Randy Dunlap
Signed-off-by: Linus Torvalds -
If you use KCONFIG_ALLCONFIG (even with empty file) you get broken
allmodconfig/allyesconfig; CONFIG_MODULES gets turned off, with obvious
massive fallout.Breakage had been introduced when conf_set_all_new_symbols() got used
for allmodconfig et.al.What happens is that sym_calc_value(modules_sym) done in
conf_read_simple() sets SYMBOL_VALID on both modules_sym and MODULES.
When we get to conf_set_all_new_symbols(), we set sym->def[S_DEF_USER]
on everything, but it has no effect on sym->curr for the symbols that
already have SYMBOL_VALID - these are stuck.Solution: use sym_clear_all_valid() in there. Note that it makes
reevaluation of modules_sym redundant - sym_clear_all_valid() will do
that itself.[ Fixes http://bugzilla.kernel.org/show_bug.cgi?id=11512, says Alexey ]

The text section stays in memory without ever leaving. With the exception
of modules, but modules know how to handle that case. With the dynamic
ftrace tracer, we need to make sure that it does not try to modify code
that no longer exists. The only safe section is .text.This patch changes the recordmcount script to only record the mcount calls
in the .text sections.Signed-off-by: Steven Rostedt
Signed-off-by: Ingo Molnar -
The recordmcount script requires that the actual arch is passed in.
This works well when ARCH=i386 or ARCH=x86_64 but does not handle the
case of ARCH=x86.This patch adds a parameter to the function to pass in the number of
bits of the architecture. So that it can determine if x86 should be
run for x86_64 or i386 archs.Signed-off-by: Steven Rostedt

Teach scripts/kconfig/Makefile and top-level Makefile that arch/*/Makefile

When bootgraph.pl parses a file, it gives one row for each initcall's
pid. But they are displayed in random (perl hash) order. Let's
sort the pids by the start time of their first initcall instead.This helps trace module initcalls, where each has a separate pid.
bootgraph.pl will show module initcalls during the initramfs; it may
also be adapted to show subsequent module initcalls.Signed-off-by: Alan Jenkins
