Documentation: update /proc/stat "intr" count summary
The sum at the beginning of line "intr" includes also unnumbered interrupts. It implies that the sum at the beginning isn't the sum of the remainder of the line, not even an estimation. Fixed the documentation to mention that. This behaviour was added to /proc/stat in commit a2eddfa95919 ("x86: make /proc/stat account for all interrupts") Signed-off-by: Jan Moskyto Matejka <mq@suse.cz> Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
