The USB core keeps track of pending resume requests for root hubs, in
order to resolve races between wakeup requests and suspends.  However
the code that does this is subject to another race (between wakeup
requests and resumes) because the WAKEUP_PENDING flag is cleared
before the resume occurs, leaving a window in which another wakeup
request might arrive.

This patch (as1447) fixes the problem by clearing the WAKEUP_PENDING
flag after the resume instead of before it.

This fixes Bugzilla #24952.

If anyone comes across a high-speed hub that (by mistake or by design)
claims to have no Transaction Translators, plugging a full- or
low-speed device into it will cause the USB stack to crash.  This
patch (as1446) prevents the problem by ignoring such devices, since
the kernel has no way to communicate with them.

In drivers/usb/host/sl811-hcd.c::sl811h_urb_enqueue(), memory is allocated
with kzalloc() and assigned to 'ep'. If we leave via the 'fail' label due
to 'if (ep->maxpacket > H_MAXPACKET)', then 'ep' will go out of scope
without having been assigned to anything, so we'll leak the memory we
allocated.
This patch fixes the leak by simply calling kfree(ep); before jumping to
the 'fail' label.

Gadget MUSB driver handles dma mappings in musb_gadget_queue(). Where as it is
possible for  dma code to reject the usb request later at ->channel_program()
called from txstate()/rxstate()

For example ->channel_program in tusb6010_omap.c:

static int tusb_omap_dma_program(struct dma_channel *channel, u16 packet_sz,
        u8 rndis_mode, dma_addr_t dma_addr, u32 len)
{
...
	if (unlikely(dma_addr & 0x1) || (len < 32) || (len > packet_sz))
		return false;
...
	if (dma_addr & 0x2)
		return false;
...
}

In this case, usb request will be handled in PIO mode which renders dma mapping
operations unnecessary.

This patch adds an api to allow dma code to indicate incompatibility with usb
request. Gadget musb driver call this api, if available, before dma mappings to
avoid any unnecessary mapping operations.

If dma buffers are mapped by a higher layer, with a boolean musb_request.mapped
it is still possible to call dma_sync_single_for_device() from
musb_g_giveback(), even if txstate()/rxstate() has called unmap_dma_buffer()
before falling back to pio mode.

Moreover, check for musb_ep->dma is moved within map_dma_buffer() so where
applicable checks for it are removed. And where possible, checks for
is_dma_capable() are merged with buffer map state check.

musb_probe() only regards 0 as a wrong IRQ number, despite platform_get_irq()
that it calls returns -ENXIO in that case. It leads to musb_init_controller()
calling request_irq() with a negative IRQ number, and when it naturally
fails, the following is printed to the console:

request_irq -6 failed!
musb_init_controller failed with status -19

Fix musb_probe() to filter out the error values as well as 0.

This patch fixes kernel panic during s2ram, which is caused
by the below:

	- musb is not put into drv data of musb platform device if
	CONFIG_USB_MUSB_HDRC_HCD is defined

	- glue layer driver always get musb instance via platform_get_drvdata.

The patch fixes the issue by always puting musb into drv data
of musb platform device, which is doable even the platform device
is a host controller device.

Allow non-ARM SMP processors to use the SMP_ON_UP feature.  CPUs
supporting SMP must have the new CPU ID format, so check for this first.
Then check for ARM11MPCore, which fails the MPIDR check.  Lastly check
the MPIDR reports multiprocessing extensions and that the CPU is part of
a multiprocessing system.

Ensure that the ISA/PCI IO space accessors are properly ordered on
ARMv6+ architectures.  These should always be ordered with respect to
all other accesses.

This also fixes __iormb() and __iowmb() not being visible to ioread/
iowrite if a platform defines its own MMIO accessors.

Disable the initrd if the passed address already overlaps the reserved
region.  This avoids oopses on Netwinders when NeTTrom tells the kernel
that an initrd is located at mem+4MB, but this overlaps the BSS,
resulting in the kernels in-use BSS being freed.

This should be applied to v2.6.37-stable.

0ea12930 (arm: return both physical and virtual addresses from addruart)
changed the way the 'addruart' worked, making it return both the virt
and phys addresses.  Unfortunately, for footbridge, these were reversed.
Fix that.  Tested on Netwinder.

We should not report incomplete blocks on error.  Return the number of
bytes successfully transferred, rounded down to the nearest block.

  Revert "UBI: use mtd->writebufsize to set minimal I/O unit size"

Do not respond with -EINVAL to EVIOCGKEYCODE for not-yet-mapped
scancodes, but rather return KEY_RESERVED.

This fixes breakage with Ubuntu's input-kbd utility that stopped
returning full keymaps for remote controls.

Since check_prlimit_permission always fails in the case of SUID/GUID
processes, such processes are not able to read or set their own limits.
This commit changes this by assuming that process can always read/change
its own limits.
