Arithmetic conversion in the mask computation makes the upper word
of the second argument passed down to mtd->read_oob(), be always 0
(assuming 'offs' being a 64-bit signed long long type, and

Commit log for commit 517d3cc1
("[libata] ata_piix: Enable parallel scan") says:

    This patch turns on parallel scanning for the ata_piix driver.
    This driver is used on most netbooks (no AHCI for cheap storage it seems).
    The scan is the dominating time factor in the kernel boot for these
    devices; with this flag it gets cut in half for the device I used
    for testing (eeepc).
    Alan took a look at the driver source and concluded that it ought to be safe
    to do for this driver.  Alan has also checked with the hardware team.

and it is all true but once we put all things together additional
constraints for PATA controllers show up (some hardware registers
have per-host not per-port atomicity) and we risk misprogramming
the controller.

I used the following test to check whether the issue is real:

  @@ -736,8 +736,20 @@ static void piix_set_piomode(struct ata_
   			(timings[pio][1] << 8);
   	}
   	pci_write_config_word(dev, master_port, master_data);
  -	if (is_slave)
  +	if (is_slave) {
  +		if (ap->port_no == 0) {
  +			u8 tmp = slave_data;
  +
  +			while (slave_data == tmp) {
  +				pci_read_config_byte(dev, slave_port, &tmp);
  +				msleep(50);
  +			}
  +
  +			dev_printk(KERN_ERR, &dev->dev, "PATA parallel scan "
  +				   "race detected\n");
  +		}
   		pci_write_config_byte(dev, slave_port, slave_data);
  +	}

   	/* Ensure the UDMA bit is off - it will be turned back on if
   	   UDMA is selected */

and it indeed triggered the error message.

Lets fix all such races by adding an extra locking to ->set_piomode
and ->set_dmamode methods for PATA controllers.

[ Alan: would be better to take the host lock in libata-core for these
  cases so that we fix all the adapters in one swoop.  "Looks fine as a
  temproary quickfix tho" ]

Tested on: 855 (David), and 945GM, 965GM, GM45, and G45 (anholt)

The lack of a proper LRU was partially worked around by taking the fence
from the object containing the oldest seqno.  But if there are multiple
objects inactive, then they don't have seqnos and the first fence reg
among them would be chosen.  If you were trying to copy data between two
mappings, this could result in each page fault stealing the fence from
the other argument, and your application hanging.

-tip testing found that this patch breaks the build on x86 if
CONFIG_KALLSYMS is disabled:

 kernel/module.c: In function ‘load_module’:
 kernel/module.c:2367: error: ‘struct module’ has no member named ‘sect_attrs’
 distcc[8269] ERROR: compile kernel/module.c on ph/32 failed
 make[1]: *** [kernel/module.o] Error 1
 make: *** [kernel] Error 2
 make: *** Waiting for unfinished jobs....

Commit 1b364bf4 misses the fact that section attributes are only
built and dealt with if kallsyms is enabled. The patch below fixes
this.

( note, technically speaking this should depend on CONFIG_SYSFS as
  well but this patch is correct too and keeps the #ifdef less
  intrusive - in the KALLSYMS && !SYSFS case the code is a NOP. )

it still gets used without checking in add_notes_attrs()
