Commit log for commit 517d3cc15b36392e518abab6bacbb72089658313
("[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" ]

This patch fixes the wrong headphone output routing for MacBookPro 3,1/4,1
quirk with ALC889A codec, which caused the silent headphone output.

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.

> James Bottomley (1):
> module: workaround duplicate section names
-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: *** [kernel] Error 2
make: *** Waiting for unfinished jobs....
Commit 1b364bf 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. )

The root cause is a duplicate section name (.text); is this legal?
[ Amerigo Wang: "AFAIK, yes." ]
However, there's a problem with commit
6d76013381ed28979cd122eb4b249a88b5e384fa in that if you fail to allocate
a mod->sect_attrs (in this case it's null because of the duplication),
it still gets used without checking in add_notes_attrs()
This should fix it
[ This patch leaves other problems, particularly the sections directory,
but recent parisc toolchains seem to produce these modules and this
prevents a crash and is a minimal change -- RR ]

Before the rewrite copy_event_to_user always wrote a terqminating '\0'
byte to user space after the filename. Since the rewrite that
terminating byte was skipped if your filename is exactly a multiple of
event_size. Ouch!
So add one byte to name_size before we round up and use clear_user to
set userspace to zero like /dev/zero does instead of copying the
strange nul_inotify_event. I can't quite convince myself len_to_zero
will never exceed 16 and even if it doesn't clear_user should be more
efficient and a more accurate reflection of what the code is trying to
do.
