CONFIG_MODVERSIONS=y results in a .mod.c for every compiled file in the kernel.
Issuing a 'make cscope' on a compiled kernel tree results in the cscope files
containing *.mod.c files.
[prarit@prarit linux]# make cscope
[prarit@prarit linux]# cat cscope.files | grep mod.c | wc -l
4807
These files are not useful for cscope and should be ignored. For example,
# line filename / context / line
1 105 arch/x86/kvm/kvm-intel.mod.c <<GLOBAL>>
{ 0x618911fc, __VMLINUX_SYMBOL_STR(numa_node) },
2 508 drivers/block/mtip32xx/mtip32xx.h <<GLOBAL>>
int numa_node;
3 55 drivers/block/mtip32xx/mtip32xx.mod.c <<GLOBAL>>
{ 0x618911fc, __VMLINUX_SYMBOL_STR(numa_node) },
4 37 drivers/cpufreq/acpi-cpufreq.mod.c <<GLOBAL>>
{ 0x618911fc, __VMLINUX_SYMBOL_STR(numa_node) },
<snip>
Add an export to RCS_FIND_IGNORE so it can be used in scripts/tags.sh and
add explicitly ignore *.mod.c files.
