  "message": "highmem: Fix race in debug_kmap_atomic() which could cause warn_count to underflow\n\ndebug_kmap_atomic() tries to prevent ever printing more than 10\nwarnings, but it does so by testing whether an unsigned integer\nis equal to 0. However, if the warning is caused by a nested\nIRQ, then this counter may underflow and the stream of warnings\nwill never end.\n\nFix that by using a signed integer instead.\n\nSigned-off-by: Soeren Sandmann Pedersen \u003csandmann@redhat.com\u003e\nCc: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nCc: a.p.zijlstra@chello.nl\nCc: \u003cstable@kernel.org\u003e # .31.x\nLKML-Reference: \u003cye8zl7b8ktj.fsf@camel23.daimi.au.dk\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n",
