2017-02-28ARM: mm: round the initrd reservation to page boundariesRussell King
Round the initrd memblock reservation to page boundaries to prevent other data sharing the initrd pages. This prevents an allocation possibly overlapping with the initrd, which would later get trampled on in free_initrd_mem(). Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2017-02-28ARM: mm: clean up initrd initialisationRussell King
Rather than repeatedly testing phys_initrd_size to see if the initrd is still enabled, return from the new function to avoid executing the remaining initialisation. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2017-02-28ARM: mm: move initrd init code out of arm_memblock_init()Russell King
Move the ARM initrd initialisation code out of arm_memblock_init() into its own function, so it can be cleaned up. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2017-02-28ARM: 8655/1: improve NOMMU definition of pgprot_*()Arnd Bergmann
The tegra DRM driver produces a harmless warning when built for NOMMU: drivers/gpu/drm/tegra/gem.c: In function 'tegra_drm_mmap': drivers/gpu/drm/tegra/gem.c:508:12: unused variable 'prot' This is because pgprot_writecombine() on ARM returns a constant and ignores its argument. The version in asm-generic doesn't have that problem, so let's use that one instead. We don't actually care about the value on NOMMU, and this is consistent with what some other architectures do.

2017-02-28ARM: 8654/1: decompressor: add strlen prototypeArnd Bergmann
The decompress.c file contains a declaration for strstr() so we can include some compression library code.

2017-02-28ARM: 8650/1: module: handle negative R_ARM_PREL31 addends correctlyArd Biesheuvel
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. Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>

VECTORS_BASE displays the exception base address. Now on no-MMU as the exception base address is dynamically estimated, define VECTORS_BASE to the variable holding it.

No-MMU dynamic exception base address configuration on CP15 processors.

2017-02-28ARM: 8646/1: mmu: decouple VECTORS_BASE from KconfigAfzal Mohammed
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.

2017-02-28ARM: 8640/1: Add support for CONFIG_DEBUG_VIRTUALFlorian Fainelli
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).

2017-02-28ARM: 8637/1: Adjust memory boundaries after reservationsLaura Abbott
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.
