2007-10-19x86: fix global_flush_tlb() bugIngo Molnar
While we were reviewing pageattr_32/64.c for unification, Thomas Gleixner noticed the following serious SMP bug in global_flush_tlb(): down_read(&init_mm.mmap_sem); list_replace_init(&deferred_pages, &l); up_read(&init_mm.mmap_sem); this is SMP-unsafe because list_replace_init() done on two CPUs in parallel can corrupt the list. This bug has been introduced about a year ago in the 64-bit tree: commit ea7322decb974a4a3e804f96a0201e893ff88ce3 Author: Andi Kleen <ak@suse.de> Date: Thu Dec 7 02:14:05 2006 +0100 [PATCH] x86-64: Speed and clean up cache flushing in change_page_attr down_read(&init_mm.mmap_sem); - dpage = xchg(&deferred_pages, NULL); + list_replace_init(&deferred_pages, &l); up_read(&init_mm.mmap_sem); the xchg() based version was SMP-safe, but list_replace_init() is not. So this "cleanup" introduced a nasty bug. why this bug never become prominent is a mystery - it can probably be explained with the (still) relative obscurity of the x86_64 architecture. the safe fix for now is to write-lock init_mm.mmap_sem.

2007-10-19ide: set drive->autotune in ide_pci_setup_ports()Bartlomiej Zolnierkiewicz
Majority of host drivers using IDE PCI layer set drive->autotune, the only exceptions are: generic.c ns87415.c rz1000.c trm290.c * no ->set_pio_mode method it821x.c: * if memory allocation fails drive->autotune won't be set (but there also won't be ->set_pio_mode method in such case) piix.c: * MPIIX controller (no ->init_hwif method so also no ->set_pio_mode method) However if there is no ->set_pio_mode method there are no changes in behavior w.r.t.
