9524705c86 MX35: Fix bogus L2 cache settings
i.MX35 CPUs marked with "MCIMX357CJQ5C M99V CTHA0943B" are coming with bogus
L2 cache settings. If these settings are kept unmodified prior enabling the L2
cache the CPU runs amok immediately when its enabled.

This fix should not hurt already working CPUs, as they are using the written
register value already.

Its currently unknown if its possible to detect the production lot from the
software to fix only affected CPUs.

While at it, make sure that mxc_init_l2x0 is only executed on i.MX31/35

The HAVE_NET_MACB configuration option is located in the net Kconfig file
as it may be setup by ARM/AT91 and AVR32 chips.

This merge keep the support of the old machine ID

Now we use the ATAG to pass the hardware functionality to kernel
with this board revision encoding
 bit 0:
     0 => 1 sd/mmc slot
     1 => 2 sd/mmc slots connectors (board from revision C)

846afbd1fe GIC: Dont disable INT in ack callback
Masking in the ack callback fails to work with handle_percpu_irq and handle_edge_irq.
The interrupt stays disabled after the first invocation since percpu and edge irq do
not unmask an interrupt after handling it. For handle_level_irq masking in the ack
is redundant because ack is always called after mask in the mask_ack function.

Masking in the ack function is required only when __do_IRQ was used instead of flow
handlers, but using __do_IRQ has been deprecated.

Remove the masking of interrupt from the ack callback.

ec706dab29 ARM: add a vma entry for the user accessible vector page
The kernel makes the high vector page visible to user space. This page
contains (amongst others) small code segments that can be executed in
user space.  Make this page visible through ptrace and /proc/<pid>/mem
in order to let gdb perform code parsing needed for proper unwinding.

For example, the ERESTART_RESTARTBLOCK handler actually has a stack
frame -- it returns to a PC value stored on the user's stack.   To
unwind after a "sleep" system call was interrupted twice, GDB would
have to recognize this situation and understand that stack frame
layout -- which it currently cannot do.

We could fix this by hard-coding addresses in the vector page range into
GDB, but that isn't really portable as not all of those addresses are
guaranteed to remain stable across kernel releases.  And having the gdb
process make an exception for this page and get  content from its own
address space for it looks strange, and it is not future proof either.

Being located above PAGE_OFFSET, this vma cannot be deleted by
user space code.

7c63984b86 ARM: do not define VMALLOC_END relative to PAGE_OFFSET
VMALLOC_END is supposed to be an absolute value, while PAGE_OFFSET may
vary depending on the selected user:kernel memory split mode through
CONFIG_VMSPLIT_*.  In fact, the goal of moving PAGE_OFFSET down is to
accommodate more directly addressed RAM by the kernel below the vmalloc
area, and having VMALLOC_END move along PAGE_OFFSET is rather against
the very reason why PAGE_OFFSET can be moved in the first place.
