Fix pagemap_read() use of struct mm_walk

2008-07-05T20:13:44Z

Fix some issues in pagemap_read noted by Alexey: - initialize pagemap_walk.mm to "mm" , so the code starts working as advertised - initialize ->private to "&pm" so it wouldn't immediately oops in pagemap_pte_hole() - unstatic struct pagemap_walk, so two threads won't fsckup each other (including those started by root, including flipping ->mm when you don't have permissions) - pagemap_read() contains two calls to ptrace_may_attach(), second one looks unneeded. - avoid possible kmalloc(0) and integer wraparound.

Move _RET_IP_ and _THIS_IP_ to include/linux/kernel.h

2008-07-05T20:10:50Z

These two macros are useful beyond lock debugging. Moved definitions from include/linux/debug_locks.h to include/linux/kernel.h, so code that needs them does not have to include the former, which would have been a less intuitive choice of a header.

Fix clear_refs_write() use of struct mm_walk

ahci: give another shot at clearing all bits in irq_stat

2008-07-05T20:05:37Z

Commit ea0c62f7cf70f13a67830471b613337bd0c9a62e tried to clear all bits in irq_stat but it didn't actually achieve that as irq_stat was anded with port_map right after read. This patch makes ahci driver always use the unmasked value to clear irq_status. While at it, add explanation on the peculiarities of ahci IRQ clearing. This was spotted by Linus Torvalds.
