USB: ehci-tegra: remove PORT_RWC_BITS when setting USB_PORT_FEAT_ENABLE

In the SetPortFeature/USB_PORT_FEAT_ENABLE case, ehci_hub_control()
would read from status_reg, modify the value, and write the result back to
status_reg. This would clear any bits in PORT_RWC_BITS that were set in
the register. Fix this by masking these bits off before the write.

This is logically the same change as 6d5f89c "USB: EHCI: remove
PORT_RWC_BITS when clearing USB_PORT_FEAT_ENABLE", but applied to the
Tegra driver rather than the USB core.

are marked as non-removable.

mmc_card_is_removable() causes some problems, because
mmc_card_is_removable() is overloaded with CONFIG_MMC_UNSAFE_RESUME

filesystem is stored on SD, but we also have external SD card slots
where we want automatic card detection.

Refine the check to only apply to hosts marked as MMC_CAP_NONREMOVABLE,
which is defined to mean that the card is *really* nonremovable. This

VM: add "vm_mmap()" helper function

vm_mmap() does the same thing as do_mmap(), but additionally does the
required VM locking.

This uninlines (and rewrites it to be clearer) do_mmap(), which sadly
duplicates it in mm/mmap.c and mm/nommu.c.  But that way we don't have
to export our internal do_mmap_pgoff() function.

Some day we hopefully don't have to export do_mmap() either, if all
modular users can become the simpler vm_mmap() instead.  We're actually
very close to that already, with the notable exception of the (broken)
