SubjectRE: Unexpected lock during "Calibrating delay loop" and failure to compile without "HighRes"
Date

Compilation with high-res turned off:


add #define do_gettimeoffset() do_slow_gettimeoffset() at line 283 in
arch/i386/kernel/time.c

their was a
"static unsigned long (*do_gettimeoffset)(void) = do_slow_gettimeoffset;"
instead of the #define found for other configuration

at line 875

#ifndef do_gettimeoffset
do_gettimeoffset = do_fast_gettimeoffset;
#endif

would be compiled even when the CONFIG_X86_TSC is off.
