7b96ddd02e ARM: 8654/1: decompressor: add strlen prototype
The decompress.c file contains a declaration for strstr() so we can
include some compression library code.

With the updated LZ4 implementation, we run into the same problem again
for strlen():

include/linux/cpumask.h: In function 'cpumask_parse':

This adds another declaration to work around the new problem.

050d18d1c6 ARM: 8650/1: module: handle negative R_ARM_PREL31 addends correctly
According to the spec 'ELF for the ARM Architecture' (IHI 0044E),
addends for R_ARM_PREL31 relocations are 31-bit signed quantities,
so we need to sign extend the value to 32 bits before it can be used
as an offset in the calculation of the relocated value.

We have not been bitten by this because these relocations are usually
emitted against the start of a section, which means the addends never
assume negative values in practice. But it is a bug nonetheless, so fix
it.

VECTORS_BASE displays the exception base address. Now on no-MMU as

d2ca5f2491 ARM: 8646/1: mmu: decouple VECTORS_BASE from Kconfig
For MMU configurations, VECTORS_BASE is always 0xffff0000, a macro
definition will suffice.

For no-MMU, exception base address is dynamically determined in
subsequent patches. To preserve bisectability, now make the
macro applicable for no-MMU scenario too.

Thanks to 0-DAY kernel test infrastructure that found the
bisectability issue. This macro will be restricted to MMU case upon
dynamically determining exception base address for no-MMU.

Once exception address is handled dynamically for no-MMU,
VECTORS_BASE can be removed from Kconfig.

e377cd8221 ARM: 8640/1: Add support for CONFIG_DEBUG_VIRTUAL
x86 has an option: CONFIG_DEBUG_VIRTUAL to do additional checks on
virt_to_phys calls. The goal is to catch users who are calling
virt_to_phys on non-linear addresses immediately. This includes caller
using __virt_to_phys() on image addresses instead of __pa_symbol(). This
is a generally useful debug feature to spot bad code (particulary in
drivers).

985626564e ARM: 8637/1: Adjust memory boundaries after reservations
adjust_lowmem_bounds is responsible for setting up the boundary for
lowmem/highmem. This needs to be setup before memblock reservations can
occur. At the time memblock reservations can occur, memory can also be
removed from the system. The lowmem/highmem boundary and end of memory
may be affected by this but it is currently not recalculated. On some
systems this may be harmless, on others this may result in incorrect
ranges being passed to the main memory allocator. Correct this by
recalculating the lowmem/highmem boundary after all reservations have
been made.
