Fix spurious KCOV coverage from interrupts and add a test.
Ignore some additional files that lead to large amounts
of uninteresting coverage.
As a reference point, tracing a simple open system call
produces ~10K PCs with these changes instead of ~45K PCs.

Dmitry Vyukov (4):
  x86/entry: Remove unwanted instrumentation in common_interrupt()
  kcov: add interrupt handling self test
  module: Fix KCOV-ignored file name
  x86: Ignore stack unwinding in KCOV
