Commit 721449bf added support for using the ADMA notifier bits to determine which commands to check for completion. However there have been reports that this causes command timeouts in certain cases. This is still being investigated. In addition, apparently the notifiers won't work if ADMA is disabled on the other port as a result of an ATAPI device being connected, and we don't handle this case properly. For now, just restore the previous behavior of checking all active commands to see if they are complete, without relying on the notifiers. Signed-off-by:

Recently I got my hands on nVidia's MCP61 PM-AM board, and it contains IDE chip configured by BIOS with only primary channel enabled. This confuses code which probes for device DMA capabilities - it gets 0x60 (happy duplex device) from primary channel BMDMA, but 0xFF (nobody here) from secondary channel BMDMA. Due to this code then believes that chip is simplex. I do not address this problem in my patch, as I'm not sure how to handle this. Probably ata_pci_init_one should have bitmap of enabled/possible interfaces instead of their count, but it looks like quite intrusive change, and maybe we do not care - for device with only one channel simplex and regular DMA engines are same. But making device simplex pointed out that support for DMA on simplex devices is currently broken - ata_dev_xfermask tests whether device is simplex and if it is whether DMA engine was assigned to this port. If not then it strips out DMA bits from device. Problem is that code which assigns DMA engine to port in ata_set_mode first detect device mode and assigns DMA engine to channel only if some DMA capable device was found. And as xfermask stripped out DMA bits, host->simplex_claimed is always NULL with current implementation. By allowing DMA either if simplex_claimed is NULL or if it points to current port DMA can be finally used - it gets assigned to first port which contains any DMA capable device.

x86_64 nvidia_bugs() broke when we bailed out on not finding the HPET. However, the quirk works by checking for _not_ finding the HPET... Delete the nvidia_hpet_detected flag and simply test for not finding the HPET, which is simple to do now that acpi_table_parse returns 1 on failure. Signed-off-by:

For 2.6.20 it mostly used to just not work, for 2.6.21-rc it crashes, this seems to be down to luck (bad or good). The libata-acpi code needs to avoid doing PCI work on non-PCI devices. This is one hack although it's not pretty and perhaps there is a "right" way to check if a struct device * is PCI ? Signed-off-by:

In my previous x86_64 thread fix, I forgot to initialize thread.arch.fs in arch_prctl. A process calling arch_prctl to set %fs would lose it on the next context switch. It also turns out that you can switch to a process which is in the process of exiting and which has lost its mm. In this case, it's worse than useless to try to call arch_prctl on the host process.

IA64 and ARM-OABI are currently using their own version of epoll compat_ code. An architecture needs epoll_event translation if alignof(u64) in 32 bit mode is different from alignof(u64) in 64 bit mode. If an architecture needs epoll_event translation, it must define struct compat_epoll_event in asm/compat.h and set CONFIG_HAVE_COMPAT_EPOLL_EVENT and use compat_sys_epoll_ctl and compat_sys_epoll_wait. All 64 bit architecture should use compat_sys_epoll_pwait. [sfr: restructure and move to fs/compat.c, remove MIPS version of compat_sys_epoll_pwait, use __put_user_unaligned] Signed-off-by:

[Bluetooth] Fix socket locking in hci_sock_dev_event() hci_sock_dev_event() uses bh_lock_sock() to lock the socket lock. This is not deadlock-safe against locking of the same socket lock in l2cap_connect_cfm() from softirq context. In addition to that, hci_sock_dev_event() doesn't seem to be called from softirq context, so it is safe to use lock_sock()/release_sock() instead. The lockdep warning can be triggered on my T42p simply by switching the Bluetooth off by the keyboard button. ================================= [ INFO: inconsistent lock state ] 2.6.21-rc2 #4 --------------------------------- inconsistent {in-softirq-W} -> {softirq-on-W} usage. khubd/156 [HC0[0]:SC0[0]:HE1:SE1] takes: (slock-AF_BLUETOOTH){-+..}, at: [<e0ca5520>] hci_sock_dev_event+0xa8/0xc5 [bluetooth] {in-softirq-W} state was registered at: [<c012d1db>] mark_lock+0x59/0x414 [<e0cef688>] l2cap_connect_cfm+0x4e/0x11f [l2cap] [<c012dfd7>] __lock_acquire+0x3e5/0xb99 [<e0cef688>] l2cap_connect_cfm+0x4e/0x11f [l2cap] [<c012e7f2>] lock_acquire+0x67/0x81 [<e0cef688>] l2cap_connect_cfm+0x4e/0x11f [l2cap] [<c036ee72>] _spin_lock+0x29/0x34 [<e0cef688>] l2cap_connect_cfm+0x4e/0x11f [l2cap] [<e0cef688>] l2cap_connect_cfm+0x4e/0x11f [l2cap] [<e0ca17c3>] hci_send_cmd+0x126/0x14f [bluetooth] [<e0ca4ce4>] hci_event_packet+0x729/0xebd [bluetooth] [<e0ca205b>] hci_rx_task+0x2a/0x20f [bluetooth] [<e0ca209d>] hci_rx_task+0x6c/0x20f [bluetooth] [<c012d7be>] trace_hardirqs_on+0x10d/0x14e [<c011ac85>] tasklet_action+0x3d/0x68 [<c011abba>] __do_softirq+0x41/0x92 [<c011ac32>] do_softirq+0x27/0x3d [<c0105134>] do_IRQ+0x7b/0x8f [<c0103dec>] common_interrupt+0x24/0x34 [<c0103df6>] common_interrupt+0x2e/0x34 [<c0248e65>] acpi_processor_idle+0x1b3/0x34a [<c0248e68>] acpi_processor_idle+0x1b6/0x34a [<c010232b>] cpu_idle+0x39/0x4e [<c04bab0c>] start_kernel+0x372/0x37a [<c04ba42b>] unknown_bootoption+0x0/0x202 [<ffffffff>] 0xffffffff Signed-off-by:Jiri Kosina <jkosina@suse.cz> Acked-by:

Also PTRACE_OLDSETOPTIONS should be accepted, as done by kernel/ptrace.c and forced by binary compatibility. UML/32bit breaks because of this - since it is wise enough to use PTRACE_OLDSETOPTIONS to be binary compatible with 2.4 host kernels. Until 2.6.17 (commit f0f2d653) we had: default: return sys_ptrace(request, pid, addr, data); Instead here we have: case PTRACE_GET_THREAD_AREA: case ...: return sys_ptrace(request, pid, addr, data); default: return -EINVAL; This change was a style change - when a case is added, it must be explicitly tested this way. In this case, not enough testing was done. Cc: Andi Kleen <ak@suse.de> Signed-off-by:

Since both UML consoles do not use percpu variables, they may be called when the cpu is still offline, and they may be marked CON_ANYTIME (this is documented in kernel/printk.c, grep for CON_ANYTIME to find mentions of this). Works well in testing done with lock debug enabled, should be safe but is not needed for next release. This would probably help also stderr_console.c, but this is yet to test. Signed-off-by:

One change introduced by the workqueue removal patch is that adding an interface that is up to a bridge which is also up does not ever call br_stp_enable_port(), leaving the port in DISABLED state until we do ifconfig down and up or link events occur.
