The patch below adds ARM ptrace functions to get the process load address.
This is required for useful userspace debugging on mmuless systems. These
values are obtained by reading magic offsets with PTRACE_PEEKUSR, as on other
nommu targets. I picked arbitrary large values for the offsets.

This patch sets bit 0 in the startup address passed to the secondary
CPUs so that they branch into Thumb-2 mode.

Modules compiled to Thumb-2 have two additional relocations needing to
be resolved at load time, R_ARM_THM_CALL and R_ARM_THM_JUMP24, for BL
and B.W instructions. The maximum Thumb-2 addressing range is +/-2^24
(+/-16MB) therefore the MODULES_VADDR macro in asm/memory.h is set to
(MODULES_END - 8MB) for the Thumb-2 compiled kernel.

This patch adds various C and assembler macros that help with using
the unified assembler syntax for compiling files to either ARM or
Thumb-2 modes.
Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>

Since the Thumb-2 instructions can be 16-bit wide, data in the .text
sections may not be aligned to a 32-bit word and this leads to unaligned
exceptions. This patch does not affect the ARM code generation.

Fix i2c_board_info definitions - we were defining the 'type' field

Removed the LBD support that isn't of any use right now at least,
then remove remnants of the TCM config flags that somehow crept
in by mistake (not yet merged patch for 2.6.32) and then the usual

Pull the initial preempt_count value into a single
definition site.
Maintainers for: alpha, ia64 and m68k, please have a look,
your arch code is funny.
The header magic is a bit odd, but similar to the KERNEL_DS
one, CPP waits with expanding these macros until the
INIT_THREAD_INFO macro itself is expanded, which is in
arch/*/kernel/init_task.c where we've already included
sched.h so we're good.

This makes the VIC resume from suspend flagged IRQ:s identical to
the flags indicating all possible interrupts. This is perhaps not
the optimal setting but setting it to 0 makes the system suspend
and never come back again (all IRQ sources masked off).

As slab is available early now, use kzalloc() rather than
alloc_bootmem_low() in pxa_init_gpio_chip().

This adds a few default locks to the clocks (the clocks were used
before the locks were initialized by code), then renames the clocks
a bit to fit with the latest driver names (some changed during
review). Lastly it moves the initialization of the clock debugfs
entry to module_init() initcall level since the debugfs isn't up
in core_initcall().

Update the link script for ARM to use PAGE_SIZE instead of hard-
coded 4096. Also the old RODATA macro is deprecated
for the RO_DATA(PAGE_SIZE) macro. As a consequence the PAGE_SIZE
was changed from (1UL << PAGE_SHIFT) to (_AC(1,UL) << PAGE_SHIFT)
because the linker does not understand the "UL" suffix to numeric
constants.

handle_bad_irq() expects the IRQ number to be valid (used for statistics),
