This is necessary to make some storage arrays work.

Some storage devices have more than 8 LUNs. In addition
you can hook up a WideSCSI bus to USB. In these cases even
level 2 devices can have more than 8 LUNs. For them
it is necessary to simply believe the class specific
command and report its result back to the SCSI layer.

When a signal is delivered, the information in the siginfo structure
is copied to userspace.  Good security practice dicatates that the
unused fields in this structure should be initialized to 0 so that
random kernel stack data isn't exposed to the user.  This patch adds
such an initialization to the two places where usbfs raises signals.

Main benefit of this is to get xhci connected USB scanners to work.

Some devices use a clear endpoint halt request as a 'soft reset' even if
the endpoint is not halted. This will clear the toggle and sequence on the
device side. xHCI however refuses to reset a non-halted endpoint, so instead
we need to issue a configure endpoint command on xHCI to clear its host side
toggle and sequence, and get it in sync with the device side.

The commit 97374792 ("usb: host: xhci-plat: add support for the Armada
375/38x XHCI controllers") extended the xhci-plat driver to support the Armada
375/38x SoCs, mostly by adding a quirk configuring the MBUS window.

However, that quirk was run before the clock the controllers needs has been
enabled. This usually worked because the clock was first enabled by the
bootloader, and left as such until the driver is probe, where it tries to
access the MBUS configuration registers before enabling the clock.

Things get messy when EPROBE_DEFER is involved during the probe, since as part
of its error path, the driver will rightfully disable the clock. When the
driver will be reprobed, it will retry to access the MBUS registers, but this
time with the clock disabled, which hangs forever.

Fix this by running the quirks after the clock has been enabled by the driver.

usb: fixes for v4.0-rc2

Not that many fixes this time. They have all been tested on
platforms I have around and also passed my randconfig builds.

Here's a quick summary of the changes:

Phonet function learned to not disable a disabled endpoint.

musb received a pm_runtime_irq_safe() call to fix a bug when
calling musb_pullup() (via usb_gadget_{connect,disconnect}())
with irqs disabled.

musb also got a really old fix for throughput with isochronous
endpoints by pushing URB completion to a tasklet (by means of
HCD_BH flag).

musb now can properly get its phys on musb-dsps platforms (am335x
as of now).

musb learned how to read boolean OF properties.

Old bug on how to disable dwc3-omap's IRQs got fixed finally.

A few sparse warnings here and there.

Renesas got a linkage fix.

The "Extended Compat ID OS Feature Descriptor Specification" does not
require the (sub)compatible ids to be NUL-terminated, because they
are placed in a fixed-size buffer and only unused parts of it should
contain NULs. If the buffer is fully utilized, there is no place for NULs.

Consequently, the code which uses desc->ext_compat_id never expects the
data contained to be NUL terminated.

If the compatible id is stored after sub-compatible id, and the compatible
id is full length (8 bytes), the (useless) NUL terminator overwrites the
first byte of the sub-compatible id.

If the sub-compatible id is full length (8 bytes), the (useless) NUL
terminator ends up out of the buffer. The situation can happen in the RNDIS
function, where the buffer is a part of struct f_rndis_opts. The next
member of struct f_rndis_opts is a mutex, so its first byte gets
overwritten. The said byte is a part of a mutex'es member which contains
the information on whether the muext is locked or not. This can lead to a
deadlock, because, in a configfs-composed gadget when a function is linked
into a configuration with config_usb_cfg_link(), usb_get_function()
is called, which then calls rndis_alloc(), which tries locking the same
mutex and (wrongly) finds it already locked.

This patch eliminates NUL terminating of the (sub)compatible id.

In the wrapper the IRQ disable should be done by writing 1's to the
IRQ*_CLR register. Existing code is broken because it instead writes
zeros to IRQ*_SET register.

Fix this by adding functions dwc3_omap_write_irqmisc_clr() and
dwc3_omap_write_irq0_clr() which do the right thing.

The renesas usbhs driver calls extcon_get_edev_by_phandle(), which
is defined in drivers/extcon/extcon-class.c, and that can be a
loadable module. If the extcon-class support is disabled, usbhs
will work correctly for all devices that do not need extcon.

However, if extcon-class is a loadable module, and usbhs is
built-in, the kernel fails to link. In order to solve that,
we need a Kconfig dependency that allows extcon to be disabled
but does not allow usbhs built-in if extcon is a module.

We need a pm_runtime_get_sync() call from
within musb_gadget_pullup() to make sure
registers are accessible at that time.

The problem is that musb_gadget_pullup() is
called with IRQs disabled and, because of that,
we need to tell pm_runtime that this pm_runtime_get_sync()
is IRQ safe.

We can simply add pm_runtime_irq_safe(), however, because
we need to make our read/write accessor function pointers
have been initialized before trying to use them. This means
that all pm_runtime initialization for musb_core needs to
be moved down so that when we call pm_runtime_irq_safe(),
the pm_runtime_get_sync() that it calls on the parent, won't
cause a crash due to NULL musb_read/write accessors.

.. after extensive statistical analysis of my G+ polling, I've come to
the inescapable conclusion that internet polls are bad.

Big surprise.

But "Hurr durr I'ma sheep" trounced "I like online polls" by a 62-to-38%
margin, in a poll that people weren't even supposed to participate in.
Who can argue with solid numbers like that? 5,796 votes from people who
can't even follow the most basic directions?

In contrast, "v4.0" beat out "v3.20" by a slimmer margin of 56-to-44%,
but with a total of 29,110 votes right now.

Now, arguably, that vote spread is only about 3,200 votes, which is less
than the almost six thousand votes that the "please ignore" poll got, so
it could be considered noise.

But hey, I asked, so I'll honor the votes.

I've noticed significant locking contention in memory reclaimer around
sb_lock inside grab_super_passive(). Grab_super_passive() is called from
two places: in icache/dcache shrinkers (function super_cache_scan) and
from writeback (function __writeback_inodes_wb). Both are required for
progress in memory allocator.

Grab_super_passive() acquires sb_lock to increment sb->s_count and check
sb->s_instances. It seems sb->s_umount locked for read is enough here:
super-block deactivation always runs under sb->s_umount locked for write.
Protecting super-block itself isn't a problem: in super_cache_scan() sb
is protected by shrinker_rwsem: it cannot be freed if its slab shrinkers
are still active. Inside writeback super-block comes from inode from bdi
writeback list under wb->list_lock.

This patch removes locking sb_lock and checks s_instances under s_umount:
generic_shutdown_super() unlinks it under sb->s_umount locked for write.
New variant is called trylock_super() and since it only locks semaphore,
callers must call up_read(&sb->s_umount) instead of drop_super(sb) when
they're done.

Fix up the following scripted S_ISDIR/S_ISREG/S_ISLNK conversions (or lack

 (1) Cachefiles mostly wants to use d_can_lookup() rather than d_is_dir() as
     it doesn't want to deal with automounts in its cache.

Convert the following where appropriate:

 (1) S_ISLNK(dentry->d_inode) to d_is_symlink(dentry).

 (2) S_ISREG(dentry->d_inode) to d_is_reg(dentry).

 (3) S_ISDIR(dentry->d_inode) to d_is_dir(dentry).  This is actually more
     complicated than it appears as some calls should be converted to
     d_can_lookup() instead.  The difference is whether the directory in
     question is a real dir with a ->lookup op or whether it's a fake dir with
     a ->d_automount op.

In some circumstances, we can subsume checks for dentry->d_inode not being
NULL into this, provided we the code isn't in a filesystem that expects
d_inode to be NULL if the dirent really *is* negative (ie. if we're going to
use d_inode() rather than d_backing_inode() to get the inode pointer).

Note that the dentry type field may be set to something other than
DCACHE_MISS_TYPE when d_inode is NULL in the case of unionmount, where the VFS
manages the fall-through from a negative dentry to a lower layer.  In such a
case, the dentry type of the negative union dentry is set to the same as the
type of the lower dentry.

However, if you know d_inode is not NULL at the call site, then you can use
the d_is_xxx() functions even in a filesystem.

There is one further complication: a 0,0 chardev dentry may be labelled
DCACHE_WHITEOUT_TYPE rather than DCACHE_SPECIAL_TYPE.  Strictly, this was
intended for special directory entry types that don't have attached inodes.
