OGAWA Hirofumi ff1be9ad61 Fix "fs: convert core functions to zero_user_page"
The bug was introduced by 01f2705daf.
It misses to convert the first argument, it should be "new_page".

This became a cause of fatfs corruption.

Herbert Xu da7cd59ab9 [CRYPTO] api: Read module pointer before freeing algorithm
The function crypto_mod_put first frees the algorithm and then drops
the reference to its module.  Unfortunately we read the module pointer
which after freeing the algorithm and that pointer sits inside the
object that we just freed.

So this patch reads the module pointer out before we free the object.

Thanks to Luca Tettamanti for reporting this.

Gerald Britton e9ca75b535 cciss: Fix pci_driver.shutdown while device is still active
Fix an Oops in the cciss driver caused by system shutdown while a filesystem
on a cciss device is still active.  The cciss_remove_one function only
properly removes the device if the device has been cleanly released by its
users, which is not the case when the pci_driver.shutdown method is called.

This patch adds a new cciss_shutdown function to better match the pattern
used by various SCSI drivers: deactivate device interrupts and flush caches.
It also alters the cciss_remove_one function to match and readds the
__devexit annotation that was removed when cciss_remove_one was serving as
the pci_driver.shutdown method.

	[WORKQUEUE]: cancel_delayed_work: use del_timer() instead of del_timer_sync()

was wrong, it was merged by mistake after that.

From the changelog:

	after this patch:
		...
		delayed_work_timer_fn->__queue_work() in progress.

		The latter doesn't differ from the caller's POV,

it does make a difference if the caller calls flush_workqueue() after
cancel_delayed_work(), in that case flush_workqueue() can miss this
work_struct.

Linus Torvalds b46522394d Revert "[PATCH] x86: Drop cc-options call for all options supported in gcc 3.2+"
This reverts commit c8fdd24725.

It turns out the kernel was correct, and the gcc complaint was a gcc
bug.  The preferred stack boundary is expressed not in bytes, but in the
the log2() of the preferred boundary, so "-mpreferred-stack-boundary=2"
is in fact exactly what we want, but a gcc that is compiled for x86-64
will consider it an error (because the 64-bit calling sequence says that
the stack should be 16-byte aligned) even if we are then using "-m32" to
generate 32-bit code.

pci_enable_msi failure is a normal event so we should not print any error.
Going over the code I spotted a missing pci_disable_msi() leak when irq

look a lot better. All #ifdef CONFIG_PCI_MSI's have been removed.

The hardware must not see that is given ownership of a buffer until it is
completely written, and when the driver receives ownership of a buffer,
it must ensure that any other reads to the buffer reflect its final
state.  Thus, I/O barriers are added where required.

bdp->length and bdp->status in gfar_new_skb.  Hardware reordering

Eugene Surovegin 5bb96e9f24 ibm_emac: improved PHY support
Original patch is from Jeff Haran  <jharan@brocade.com> with my minor style
fixes. His comments follow:

The first problem was in the function that configures the PHY for
autonegotiation, genmii_setup_aneg(). The original code does a
read/modify/write of the autonegotiation advertizement register (reg 4),
followed by a read/modify/write of the control register (reg 0). While
the original code follows the proper procedure as per reading the IEEE
specs, what I found is that on at least one PHY model (National DP83843)
the read of the control register comes back with the soft reset bit set
(bit 15). Because of the read/modify/write operation, this causes the
write to write a 1 back to the reset bit, which initiates a software
reset of the PHY. This software reset causes the PHY to return to its
power up state which advertizes all modes of operation, thus negating
the write to the autoneg advertizement register. The modification is to
spin reading the control register until the soft reset bit is clear
before doing the modify/write.
The second problem was in the function that configures the PHY for
forced operation, genmii_setup_forced(). The original code initiates a
software reset operation via a write of a 1 to bit 15 of the control
register (reg 0), but then proceeds to do a second write to that same
register without waiting until that reset bit is cleared by the PHY
itself (which according to the IEEE specs indicates that the PHY reset
is complete). This is a violation of how one is supposed to use this
software reset feature of these PHYs and I believe was the cause of
mysterious, difficult to reproduce link failures that we've observed on
some of our systems that use this driver. The fix is to modify the
function so that it spins waiting for the reset bit to clear after doing
the soft reset and before doing the subsequent write.

Satyam Sharma 4ce61d1c7a [BLUETOOTH]: Fix locking in hci_sock_dev_event().
We presently use lock_sock() to acquire a lock on a socket in
hci_sock_dev_event(), but this goes BUG because lock_sock()
can sleep and we're already holding a read-write spinlock at
that point. So, we must use the non-sleeping BH version,
bh_lock_sock().

However, hci_sock_dev_event() is called from user context and
hence using simply bh_lock_sock() will deadlock against a
concurrent softirq that tries to acquire a lock on the same
socket. Hence, disabling BH's before acquiring the socket lock
and enable them afterwards, is the proper solution to fix
socket locking in hci_sock_dev_event().

David Woodhouse 0479ea0eab Fix incorrect prototype for ipxrtr_route_packet()
The function ipxrtr_route_packet() takes a 'len' argument of type
size_t. However, its prototype in af_ipx.c incorrectly suggests that the
corresponding argument is of type 'int' instead.

Discovered by building with --combine and letting the compiler see it
all at once.

David Woodhouse b5b82df6f4 NS16550A: Restore HS settings in EXCR2 on resume
After a suspend/resume cycle, the UART may have been reset into
low-speed mode -- either because it's actually been reset, or because
the firmware pokes at the old-style divisor registers. If we detected it
as a NS16550A SuperIO chip in the first place and set baud_base to
921600, then we should do so again in the resume path.

This patch adds that code to serial8250_resume_port(), and also makes
serial8250_resume() actually call serial8250_resume_port() for each port
instead of just calling uart_resume_port() directly. And thus fixes
serial port operation after suspend/resume.

It also fixes a bogus comment where we write the EXCR2 register with a
comment saying /* EXCR1 */
