I chased down a fail on ppc64 on 2.6.34-rc2 where an application that
uses shared memory was getting a SEGV.Commit baed7fc9b580bd3fb8252ff1d9b36eaf1f86b670 ("Add generic sys_ipc
wrapper") changed the second argument from an unsigned long to an int.
When we call shmget the system call wrappers for sys_ipc will sign
extend second (ie the size) which truncates it. It took a while to
track down because the call succeeds and strace shows the untruncated
size :)The patch below changes second from an int to an unsigned long which
fixes shmget on ppc64 (and I assume s390, sparc64 and mips64).Signed-off-by: Anton Blanchard
--I assume the function prototypes for the other IPC methods would cause us
to sign or zero extend second where appropriate (avoiding any security
issues). Come to think of it, the syscall wrappers for each method should do
that for us as well.

Commit 3f6da3905398826d85731247e7fbcf53400c18bd
(perf: Rework and fix the arch CPU-hotplug hooks) broke suspend to
RAM on my HP nx6325 (and most likely on other AMD-based boxes too)
by allowing amd_pmu_cpu_offline() to be executed for CPUs that are
going offline as part of the suspend process. The problem is that
cpuhw->amd_nb may be NULL already, so the function should make sure
it's not NULL before accessing the object pointed to by it.Signed-off-by: Rafael J. Wysocki

USB 3 and Wireless USB specify a logarithmic encoding of the endpoint
interval that matches the USB 2 specification. usb_fill_int_urb() didn't
know that and was filling in the interval as if it was USB 1.1. Fix
usb_fill_int_urb() for SuperSpeed devices, but leave the wireless case
alone, because David Vrabel wants to keep the old encoding.Update the struct urb kernel doc to note that SuperSpeed URBs must have
urb->interval specified in microframes.Add a missing break statement in the usb_submit_urb() interrupt URB
checking, since wireless USB and SuperSpeed USB encode urb->interval
differently. This allows xHCI roothubs to actually register with khubd.Signed-off-by: Matthew Wilcox

Contrary to the comment in fsg_add, fsg_bind calls fsg_unbind on errors,
which decreases refcount and frees the fsg_dev structure, causing trouble

The recent commit (0e530b45783f75) that moved usb_ep_autoconfig from the
__devinit section to the __init section missed the mass storage device.
Its fsg_bind() function uses the usb_ep_autoconfig() function from non
__init context leading to:
WARNING: drivers/usb/gadget/g_mass_storage.o(.text): Section mismatch in
reference from the function _fsg_bind()
to the function .init.text:_usb_ep_autoconfig()So move fsg_bind() into __init as well.

The USB PHY on current Blackfin processors is a UTMI+ level 2 PHY.
However, it has no ULPI support - so there are no registers at all.
That means accesses to ULPI_BUSCONTROL have to be abstracted away
like other MUSB registers.This fixes building for Blackfin parts again.
