6901bbc802 ARM: s5pv210_defconfig: Update for removing s5pc110_defconfig
Now that S5PC110 machines and S5PV210 machines can be built into
one kernel, update mach-s5pv210/Kconfig and s5pv210_defconfig.

Tested on Aquila(S5PC110), GONI(S5PC110), SMDKC110(S5PC110)
and SMDKV210(S5PV210).

Created and tested against linux-2.6.35-rc5.

0d87c7228a Input: adp5588-keypad - fix NULL dereference in adp5588_gpio_add()
The kpad structure is assigned to i2c client via i2s_set_clientdata()
at the end of adp5588_probe(), but in adp5588_gpio_add() we tried to
access it (via dev_get_drvdata! which is not nice at all) causing an
oops.

Let's pass pointer to kpad directly into adp5588_gpio_add() and
adp5588_gpio_remove() to avoid accessing driver data before it is
set up.

Also split out building of gpiomap into a separate function to
clear the logic.

de51257aa3 mm: fix ia64 crash when gcore reads gate area
Debian's ia64 autobuilders have been seeing kernel freeze or reboot
when running the gdb testsuite (Debian bug 588574): dannf bisected to
2.6.32 62eede62da "mm: ZERO_PAGE without
PTE_SPECIAL"; and reproduced it with gdb's gcore on a simple target.

I'd missed updating the gate_vma handling in __get_user_pages(): that
happens to use vm_normal_page() (nowadays failing on the zero page),
yet reported success even when it failed to get a page - boom when
access_process_vm() tried to copy that to its intermediate buffer.

Fix this, resisting cleanups: in particular, leave it for now reporting
success when not asked to get any pages - very probably safe to change,
but let's not risk it without testing exposure.

Why did ia64 crash with 16kB pages, but succeed with 64kB pages?
Because setup_gate() pads each 64kB of its gate area with zero pages.

831e8047eb ARM: 6279/1: highmem: fix SMP preemption bug in kmap_high_l1_vipt
smp_processor_id() must not be called from a preemptible context (this
is checked by CONFIG_DEBUG_PREEMPT).  kmap_high_l1_vipt() was doing so.
This lead to a problem where the wrong per_cpu kmap_high_l1_vipt_depth
could be incremented, causing a BUG_ON(*depth <= 0); in
kunmap_high_l1_vipt().

The solution is to move the call to smp_processor_id() after the call
to preempt_disable().

674b222292 nfs: include space for the NUL in root path
In root_nfs_name() it does the following:

        if (strlen(buf) + strlen(cp) > NFS_MAXPATHLEN) {
                printk(KERN_ERR "Root-NFS: Pathname for remote directory too long.\n");
                return -1;
        }
        sprintf(nfs_export_path, buf, cp);

In the original code if (strlen(buf) + strlen(cp) == NFS_MAXPATHLEN)
then the sprintf() would lead to an overflow.  Generally the rest of the
code assumes that the path can have NFS_MAXPATHLEN (1024) characters and
a NUL terminator so the fix is to add space to the nfs_export_path[]
buffer.
