ASoC: cs42l73: Fix mask bits for SOC_VALUE_ENUM_SINGLE

commit 1555b652970e541fa1cb80c61ffc696bbfb92bb7 upstream.

The mask bits values were wrong for the SOC_VALUE_ENUM_SINGLE for the mono mix controls.

ARM: OMAP2+: INTC: Acknowledge stuck active interrupts

commit 698b48532539484b012fb7c4176b959d32a17d00 upstream.

When an interrupt has become active on the INTC it will stay active
until it is acked, even if masked or de-asserted. The
INTC_PENDING_IRQn registers are however updated and since these are
used by omap_intc_handle_irq to determine which interrupt to handle,
it will never see the active interrupt. This will result in a storm of
useless interrupts that is only stopped when another higher priority
interrupt is asserted.

Fix by sending the INTC an acknowledge if we find no interrupts to
handle.

ARM: OMAP3: hwmod data: Correct clock domains for USB modules

commit c6c56697ae4bf1226263c19e8353343d7083f40e upstream.

OMAP3 doesn't contain "l3_init_clkdm" clock domain. Use the
proper clock domains for USB Host and USB TLL modules.

Gets rid of the following warnings during boot
 omap_hwmod: usb_host_hs: could not associate to clkdm l3_init_clkdm
 omap_hwmod: usb_tll_hs: could not associate to clkdm l3_init_clkdm

ARM: 8027/1: fix do_div() bug in big-endian systems

commit 80bb3ef109ff40a7593d9481c17de9bbc4d7c0e2 upstream.

In big-endian systems, "%1" get the most significant part of the value, cause the instruction to get the wrong result.

When viewing ftrace record in big-endian ARM systems, we found that
the timestamp errors:

swapper-0   [001] 1325.970000:   0:120:R ==> [001]    16:120:R events/1
events/1-16 [001] 1325.970000:   16:120:S ==> [001]    0:120:R swapper
swapper-0   [000] 1325.1000000:  0:120:R   + [000]    15:120:R events/0
swapper-0   [000] 1325.1000000:  0:120:R ==> [000]    15:120:R events/0

swapper-0   [000] 1326.030000:   0:120:R ==> [000]  1150:120:R sshd

When viewed ftrace records, it will call the do_div(n, base) function, which achieved arch/arm/include/asm/div64.h in. When n = 10000000, base = 1000000, in do_div(n, base) will execute "umull %Q0, %R0, %1, %Q2".

PCM pointer callbacks in ice1712 driver check the buffer size boundary

During probe the driver allocates dummy I2C devices for RTC and ADC

In case of error (i2c_new_device(): memory allocation failure or I2C

by i2c_unregister_device().

If i2c_new_dummy() fails for RTC or ADC devices, fail also the probe

w1: fix w1_send_slave dropping a slave id

commit 6b355b33a64fd6d8ead2b838ec16fb9b551f71e8 upstream.

Previous logic,
if (avail > 8) {
	store slave;
	return;
}
send data; clear;

The logic error is, if there isn't space send the buffer and clear,
but the slave wasn't added to the now empty buffer loosing that slave
id.  It also should have been "if (avail >= 8)" because when it is 8,
there is space.

Instead, if there isn't space send and clear the buffer, then there is
always space for the slave id.

x86-64, modify_ldt: Ban 16-bit segments on 64-bit kernels

commit b3b42ac2cbae1f3cecbb6229964a4d48af31d382 upstream.

The IRET instruction, when returning to a 16-bit segment, only
restores the bottom 16 bits of the user space stack pointer.  We have
a software workaround for that ("espfix") for the 32-bit kernel, but
it relies on a nonzero stack segment base which is not available in
32-bit mode.

Since 16-bit support is somewhat crippled anyway on a 64-bit kernel
(no V86 mode), and most (if not quite all) 64-bit processors support
virtualization for the users who really need it, simply reject
attempts at creating a 16-bit segment when running on top of a 64-bit
kernel.

USB: fix crash during hotplug of PCI USB controller card

commit a2ff864b53eac9a0e9b05bfe9d1781ccd6c2af71 upstream.

The code in hcd-pci.c that matches up EHCI controllers with their
companion UHCI or OHCI controllers assumes that the private drvdata
fields don't get set too early.  However, it turns out that this field
gets set by usb_create_hcd(), before hcd-pci expects it, and this can
result in a crash when two controllers are probed in parallel (as can
happen when a new controller card is hotplugged).

The companions_rwsem lock was supposed to prevent this sort of thing,
but usb_create_hcd() is called outside the scope of the rwsem.

A simple solution is to check that the root-hub pointer has been
initialized as well as the drvdata field.  This doesn't happen until
usb_add_hcd() is called; that call and the check are both protected by
the rwsem.

This patch should be applied to stable kernels from 3.10 onward.
