6ff1046409 USB: usbfs: keep async URBs until the device file is closed
The usbfs driver manages a list of completed asynchronous URBs.  But
it is too eager to free the entries on this list: destroy_async() gets
called whenever an interface is unbound or a device is removed, and it
deallocates the outstanding struct async entries for all URBs on that
interface or device.  This is wrong; the user program should be able
to reap an URB any time after it has completed, regardless of whether
or not the interface is still bound or the device is still present.

This patch (as1222) moves the code for deallocating the completed list
entries from destroy_async() to usbdev_release().  The outstanding
entries won't be freed until the user program has closed the device
file, thereby eliminating any possibility that the remaining URBs
might still be reaped.

This fixes a bug in which a program can hang in the USBDEVFS_REAPURB
ioctl when the device is unplugged.

ee568b25ee Avoid 64-bit "switch()" statements on 32-bit architectures
Commit ee6f779b9e ("filp->f_pos not
correctly updated in proc_task_readdir") changed the proc code to use
filp->f_pos directly, rather than through a temporary variable.  In the
process, that caused the operations to be done on the full 64 bits, even
though the offset is never that big.

That's all fine and dandy per se, but for some unfathomable reason gcc
generates absolutely horrid code when using 64-bit values in switch()
statements.  To the point of actually calling out to gcc helper
functions like __cmpdi2 rather than just doing the trivial comparisons
directly the way gcc does for normal compares.  At which point we get
link failures, because we really don't want to support that kind of
crazy code.

Fix this by just casting the f_pos value to "unsigned long", which
is plenty big enough for /proc, and avoids the gcc code generation issue.

9e8912e04e Fast TSC calibration: calculate proper frequency error bounds
In order for ntpd to correctly synchronize the clocks, the frequency of
the system clock must not be off by more than 500 ppm (or, put another
way, 1:2000), or ntpd will end up giving up on trying to synchronize
properly, and ends up reseting the clock in jumps instead.

The fast TSC PIT calibration sometimes failed this test - it was
assuming that the PIT reads always took about one microsecond each (2us
for the two reads to get a 16-bit timer), and that calibrating TSC to
the PIT over 15ms should thus be sufficient to get much closer than
500ppm (max 2us error on both sides giving 4us over 15ms: a 270 ppm
error value).

However, that assumption does not always hold: apparently some hardware
is either very much slower at reading the PIT registers, or there was
other noise causing at least one machine to get 700+ ppm errors.

So instead of using a fixed 15ms timing loop, this changes the fast PIT
calibration to read the TSC delta over the individual PIT timer reads,
and use the result to calculate the error bars on the PIT read timing
properly.  We then successfully calibrate the TSC only if the maximum
error bars fall below 500ppm.

In the process, we also relax the timing to allow up to 25ms for the
calibration, although it can happen much faster depending on hardware.

a6a80e1d8c Fix potential fast PIT TSC calibration startup glitch
During bootup, when we reprogram the PIT (programmable interval timer)
to start counting down from 0xffff in order to use it for the fast TSC
calibration, we should also make sure to delay a bit afterwards to allow
the PIT hardware to actually start counting with the new value.

That will happens at the next CLK pulse (1.193182 MHz), so the easiest
way to do that is to just wait at least one microsecond after
programming the new PIT counter value.  We do that by just reading the
counter value back once - which will take about 2us on PC hardware.

When a table is being replaced, it waits for I/O to complete
before destroying the mempool, but the endio function doesn't
call mempool_free() until after completing the bio.

Fix it by swapping the order of those two operations.

The same problem occurs in dm.c with md referenced after dec_pending.
Again, we swap the order.

b2174eebd1 dm crypt: fix kcryptd_async_done parameter
In the async encryption-complete function (kcryptd_async_done), the
crypto_async_request passed in may be different from the one passed to
crypto_ablkcipher_encrypt/decrypt.  Only crypto_async_request->data is
guaranteed to be same as the one passed in.  The current
kcryptd_async_done uses the passed-in crypto_async_request directly
which may cause the AES-NI-based AES algorithm implementation to panic.

This patch fixes this bug by only using crypto_async_request->data,
which points to dm_crypt_request, the crypto_async_request passed in.
The original data (convert_context) is gotten from dm_crypt_request.

bc0fd67feb dm ioctl: validate name length when renaming
When renaming a mapped device validate the length of the new name.

The rename ioctl accepted any correctly-terminated string enclosed
within the data passed from userspace.  The other ioctls enforce a
size limit of DM_NAME_LEN.  If the name is changed and becomes longer
than that, the device can no longer be addressed by name.

Fix it by properly checking for device name length (including
terminating zero).

ee6f779b9e filp->f_pos not correctly updated in proc_task_readdir
filp->f_pos only get updated at the end of the function. Thus d_off of those
dirents who are in the middle will be 0, and this will cause a problem in
glibc's readdir implementation, specifically endless loop. Because when overflow
occurs, f_pos will be set to next dirent to read, however it will be 0, unless
the next one is the last one. So it will start over again and again.

There is a sample program in man 2 gendents. This is the output of the program
running on a multithread program's task dir before this patch is applied:

b36a50f92d thinkpad-acpi: fix module autoloading for older models
Looking at the source, there seems to be a missing * to match my DMI
string.  I mean for newer IBM and Lenovo's laptops you match either one
of the following:
MODULE_ALIAS("dmi:bvnIBM:*:svnIBM:*:pvrThinkPad*:rvnIBM:*");
MODULE_ALIAS("dmi:bvnLENOVO:*:svnLENOVO:*:pvrThinkPad*:rvnLENOVO:*");

While for older Thinkpads, you do this (for instance):
IBM_BIOS_MODULE_ALIAS("1[0,3,6,8,A-G,I,K,M-P,S,T]");

with IBM_BIOS_MODULE_ALIAS being MODULE_ALIAS("dmi:bvnIBM:bvr" __type "ET??WW")

Note there's no * terminating the string.  As result, udev doesn't load
anything because modprobe cannot find anything matching this (my
machine actually):

27ce341983 acpi: check for pxm_to_node_map overflow
It is hardly (if ever) possible but in case of broken _PXM entry we could
reach out of pxm_to_node_map array bounds in acpi_map_pxm_to_node() call.

176f9c1804 ACPI: remove doubled status checking
There was a misplaced status test (two consequent tests without a
statement in between) in acpi_bus_init for ages.  Remove it, since the
function which should be checked (acpi_os_initialize1) has BUG_ONs on
failure paths.

This reverts commit 5ec5d38a1c.

in a more clever way in the future.

ea8dbdd170 r8169: revert "r8169: read MAC address from EEPROM on init (2nd attempt)"
It fails on the following systems:
- RTL8169sc/8110sc (XID 18000000)
  reported by Tim Durack <tdurack@gmail.com> (x86)
- RTL8169sb/8110sb (XID 10000000)
  reported by Mikael Pettersson <mikpe@it.uu.se> (ARM)

The patch appeared to work on x86 for the following systems:
RTL8169sb/8110sb 10000000 PCI   (EXT)
RTL8110s         04000000 PCI   (EXT)
RTL8102e         24a00000 PCI-E (LOM)
RTL8168c/8111c   3c2000c0 PCI-E (LOM)
RTL8168b/8111b   38000000 PCI-E (LOM)
RTL8168b/8111b   38000000 PCI-E (EXT)

The patch exposes two problems:
1) while not completely wrong, mac addresses are not read correctly
   from the EEPROM
2) the MAC address registers are not correctly set

682337fe06 igb: remove ASPM L0s workaround
The L0s workaround should be moved into a pci quirk and so it is not
necessary in the driver.  This update removes the L0s workaround from the
igb driver.

This was the second half of the PCI quirk patch that Matthew Wilcox did
not pick up when he picked up the quirk patch.
