Hi Kumar.

No worries, welcome.

You should definitely not send a single patch.

$ git grep -w --name-only IRQF_DISABLED | wc -l
245

I think that's way too many modified files for a
single patch.

If you do it, please remember to change bits like
"(IRQF_<foo> | IRQF_DISABLED)" so that instead of
"(IRQF_<foo> | 0)", you use just "IRQF_<foo>".

And, maybe it'd be better to use IRQF_TRIGGER_NONE
instead of 0.

Perhaps you could send patches bundled together
in sensible chunks, say, second level directories.

Something like:

$ git grep -w --name-only IRQF_DISABLED | cut -f1,2 -d"/" | uniq -c
