After SRST, libata used to wait for nsect/lbal to be set to 1/1 for the slave device. However, some ATAPI devices don't set nsect/lbal after SRST and the wait itself isn't too useful as we're gonna wait for !BSY right after that anyway. Before reset-seq update, nsect/lbal wait failure used to be ignored and caused 30sec delay during detection. After reset-seq, all timeouts are considered error conditions making libata fail to detect such ATAPI devices. This patch limits nsect/lbal wait to around 100ms. This should give acceptable behavior to such ATAPI devices while not disturbing the heavily used code path too much. Signed-off-by:

The ata IRQ ack functions are only used when debugging. Unfortunately almost every controller that calls them can cause crashes in some configurations as there are missing checks for bmdma presence. In addition ata_port_start insists of installing DMA buffers and pad buffers for controllers regardless. The SFF controllers actually need to make that decision dynamically at controller setup time and all need the same helper - so we add ata_sff_port_start. Future patches will switch the SFF drivers to use this. Signed-off-by:

Most drivers don't seem to fill out the host->irq field, resulting in the wrong (no) irq being reported at probe time. For example, sil24 on my system: ata1: SATA max UDMA/100 cmd 0xd00008009001f000 ctl 0x0000000000000000 bmdma 0x0000000000000000 irq 0 ata2: SATA max UDMA/100 cmd 0xd000080090021000 ctl 0x0000000000000000 bmdma 0x0000000000000000 irq 0 Since they're allocated and set up in ata_host_activate(), just save them away there.

Add a prefix string parameter. Callers are responsible for any string length/alignment that they want to see in the output. I.e., callers should pad strings to achieve alignment if they want that. Add rowsize parameter. This is the number of raw data bytes to be printed per line. Must be 16 or 32. Add a groupsize parameter. This allows callers to dump values as 1-byte, 2-byte, 4-byte, or 8-byte numbers. Default is 1-byte numbers. If the total length is not an even multiple of groupsize, 1-byte numbers are printed. Add an "ascii" output parameter. This causes ASCII data output following the hex data output. Clean up some doc examples. Align the ASCII output on all lines that are produced by one call. Add a new interface, print_hex_dump_bytes(), that is a shortcut to print_hex_dump(), using default parameter values to print 16 bytes in byte-size chunks of hex + ASCII output, using printk level KERN_DEBUG.

We aren't sampling for holes in memory. Thus we encounter a section hole with empty section map pointer for SPARSEMEM and OOPs for show_mem. This issue has been seen in 2.6.21, current git and current mm. The patch below is for mainline and mm. It was boot tested for SPARSEMEM, current VMEMMAP of Andy's in mm ml and DISCONTIGMEM. A slightly different patch will be posted to stable for 2.6.21. Previous to commit f0a5a58a memory_present was called for node_start_pfn to node_end_pfn. This would cover the hole(s) with reserved pages and valid sections. Most SPARSEMEM supported arches do a pfn_valid check in show_mem before computing the page structure address. This issue was brought to my attention on IRC by Arnaldo Carvalho de Melo. Thanks to Arnaldo for testing. Signed-off-by:

1. New entries can be added to tsk->pi_state_list after task completed exit_pi_state_list(). The result is memory leakage and deadlocks. 2. handle_mm_fault() is called under spinlock. The result is obvious. 3. results in self-inflicted deadlock inside glibc. Sometimes futex_lock_pi returns -ESRCH, when it is not expected and glibc enters to for(;;) sleep() to simulate deadlock. This problem is quite obvious and I think the patch is right. Though it looks like each "if" in futex_lock_pi() got some stupid special case "else if". :-) 4. sometimes futex_lock_pi() returns -EDEADLK, when nobody has the lock. The reason is also obvious (see comment in the patch), but correct fix is far beyond my comprehension. I guess someone already saw this, the chunk: if (rt_mutex_trylock(&q.pi_state->pi_mutex)) ret = 0; is obviously from the same opera. But it does not work, because the rtmutex is really taken at this point: wake_futex_pi() of previous owner reassigned it to us. My fix works. But it looks very stupid. I would think about removal of shift of ownership in wake_futex_pi() and making all the work in context of process taking lock. From: Thomas Gleixner <tglx@linutronix.de> Fix 1) Avoid the tasklist lock variant of the exit race fix by adding an additional state transition to the exit code. This fixes also the issue, when a task with recursive segfaults is not able to release the futexes. Fix 2) Cleanup the lookup_pi_state() failure path and solve the -ESRCH problem finally. Fix 3) Solve the fixup_pi_state_owner() problem which needs to do the fixup in the lock protected section by using the in_atomic userspace access functions. This removes also the ugly lock drop / unqueue inside of fixup_pi_state() Fix 4) Fix a stale lock in the error path of futex_wake_pi() Added some error checks for verification. The -EDEADLK problem is solved by the rtmutex fixups. Signed-off-by:Thomas Gleixner <tglx@linutronix.de> Acked-by:

Alexey Kuznetsov found some problems in the pi-futex code. One of the root causes is: When a wakeup happens, we do not to stop the chain walk so we follow a not longer relevant locking chain. Drop out when this happens. Signed-off-by:

Alexey Kuznetsov found some problems in the pi-futex code. The major problem is a stale return value in rt_mutex_slowlock(): When the pi chain walk returns -EDEADLK, but the waiter was woken up during the phases where the locks were dropped, the rtmutex could be acquired, but due to the stale return value -EDEADLK returned to the caller. Reset the return value in the retry path. Signed-off-by:

sata_promise uses two different command modes - packet and TF. Packet mode is intelligent low-overhead mode while TF is the same old taskfile interface. As with other advanced interface (ahci/sil24), ATA_TFLAG_POLLING has no effect in packet mode. However, PIO commands are issued using TF interface in polling mode, so pdc_interrupt() considers interrupts spurious if ATA_TFLAG_POLLING is set. This is broken for polling NODATA commands because command is issued using packet mode but the interrupt handler ignores it due to ATA_TFLAG_POLLING. Fix pdc_qc_issue_prot() such that ATA/ATAPI NODATA commands are issued using TF interface if ATA_TFLAG_POLLING is set. This patch fixes detection failure introduced by polling SETXFERMODE.
