[MTD] [NAND] support for pxa3xx
This is preliminary since:
1. It supports only _one_ chip select at the moment. As there is no
existing platforms available using two chip selects of the NAND
controller, it shall really not include code for supporting the
2nd chip select for now, as such code cannot be verified.
2. It resorts to the default and simpliest memory based badblock
table
3. Only limited types of nand flash are currently supported. Most
PXA3xx processors come with on-chip NAND flash dies, so there
isn't much flexibility for other types of NAND.
4. The NAND controller should be configured to detect the device's
ID, thus making it difficult to use nand_scan_ident() to assist
the detection process (though it's not impossible)

[IA64] disable interrupts on exit of ia64_trace_syscall
While testing with CONFIG_VIRT_CPU_ACCOUNTING=y, I found that

So I dug the issue and finally noticed that it was caused
because of an interrupt which interrupt in the following window:

>
> ENTRY(ia64_leave_syscall)

If pUStk is true, it means we are going to return user mode, hence we fetch
ar.itc to get time at leave from system.
It seems that it is not possible to interrupt the window if pUStk is true,
because interrupts are disabled early. And also disabling interrupt makes
sense because it is safe for referring current_thread_info()->flags.
However interrupting the window while pUStk is true was possible.
The route was:
ia64_trace_syscall
-> .work_pending_syscall_end
-> .work_processed_syscall
Only in case entering the window from this route, interrupts are enabled
during in the window even if pUStk is true. I suppose interrupts must be
disabled here anyway if pUStk is true.
I'm not sure but afraid that what kind of bad effect were there, other
than crazy system time which I found.
FYI, there was a commit 6f6d75825dc49b082906b84537b4df28293c2977 that
points out a bug at same point(exit of ia64_trace_syscall) in 2006.
It can be said that there was an another bug.

HID: fixup fullspeed interval on highspeed Afatech DVB-T IR kbd
Many vendors highspeed devices give erroneously fullspeed interval value in

At the time of hid configuration this quirk calculates which highspeed interval
value gives same interval delay as, or next smaller then, what it would be if
the original value would be interpreted as fullspeed value. In subsequent urbs
that new value is used instead.
Forming the 'hid->name' in usb_hid_config() was moved up to accommodate more

In this patch the quirk is set for one such device: Afatech DVB-T 2 infrared

obviously 16ms was intended. In this case quirk calculates new value to be 8

As it stands it's impossible to use any authentication algorithms

The reason is that we're using a bit mask to check the algorithm
ID but the mask is only 32 bits wide.
After looking at how this is used in the field, I have concluded
that in the long term we should phase out state matching by IDs
because this is made superfluous by the reqid feature. For current

functions just return failure if PCI_MSI=n, so there's no reason to
have "#ifdef CONFIG_PCI_MSI" blocks in ipath_iba7220.c.

IB/ipath: Remove dependency on PCI_MSI || HT_IRQ
Before IBA7220 support was added, the ipath driver didn't support any
hardware unless PCI_MSI and/or HT_IRQ was enabled. However, the
IBA7220 can generate INTx interrupts, so it makes sense to allow the
driver to be build even if PCI_MSI=n and HT_IRQ=n.
Roland Dreier [Tue, 22 Apr 2008 01:19:14 +0000 (18:19 -0700)]
IB/ipath: Build IBA7220 code unconditionally
The new IBA7220 code added a call to ipath_init_iba7220_funcs() that
is compiled unconditionally, but only built the IBA7220 code if
PCI_MSI is enabled. Fix this by building the IBA7220 file
unconditonally.
This fixes build breakage when PCI_MSI=n, HT_IRQ=y and
INFINIBAND_IPATH=y reported by Ingo Molnar <mingo@elte.hu>:
drivers/built-in.o: In function `ipath_init_one':
ipath_driver.c:(.devinit.text+0x1e5bc): undefined reference to `ipath_init_iba7220_funcs'

IB/ipath: Remove reference to dev->class_dev
Commit 124b4dcb ("IB/ipath: add calls to new 7220 code and enable in
build") inadvertently added core to set dev->class_dev.dev back into
ib_ipath. This is completely redundant since commit 1912ffbb ("IB: Set
class_dev->dev in core for nice device symlink"), which removed
class_dev setting from low-level drivers, and also will break the build
when class_dev is removed completely from struct ib_device.

IB/ipath: Fix module parameter description for disable_sma
Describe disable_sma parameter with its name rather than the internal
ib_ipath_disable_sma variable name, so that the description shows up
properly in modinfo.

SELinux: no BUG_ON(!ss_initialized) in selinux_clone_mnt_opts
The Fedora installer actually makes multiple NFS mounts before it loads
selinux policy. The code in selinux_clone_mnt_opts() assumed that the
init process would always be loading policy before NFS was up and
running. It might be possible to hit this in a diskless environment as
well, I'm not sure. There is no need to BUG_ON() in this situation
since we can safely continue given the circumstances.
