Add <asm/neon.h> containing kernel_neon_begin/kernel_neon_end function declarations and corresponding definitions in fpsimd.c These are needed to wrap uses of NEON in kernel mode. The names are identical to the ones used in arm/ so code using intrinsics or vectorized by GCC can be shared between arm and arm64.

Bring Transparent HugePage support to ARM. The size of a transparent huge page depends on the normal page size. A transparent huge page is always represented as a pmd. If PAGE_SIZE is 4KB, THPs are 2MB. If PAGE_SIZE is 64KB, THPs are 512MB. Signed-off-by: NSteve Capper <steve.capper@linaro.org> Acked-by: NCatalin Marinas <catalin.marinas@arm.com>

The buddy allocator has a default MAX_ORDER of 11, which is too low to allocate enough memory for 512MB Transparent HugePages if our base page size is 64KB. This patch introduces MAX_ZONE_ORDER and sets it to 14 when 64KB pages are used in conjuction with THP, otherwise the default value of 11 is used.

Add huge page support to ARM64, different huge page sizes are supported depending on the size of normal pages: PAGE_SIZE is 4KB: 2MB - (pmds) these can be allocated at any time. 1024MB - (puds) usually allocated on bootup with the command line with something like: hugepagesz=1G hugepages=6 PAGE_SIZE is 64KB: 512MB - (pmds) usually allocated on bootup via command line.

As is done for other architectures, sort the exception table at build-time rather than during boot. Since sortextable appears to be a standalone C program relying on the host elf.h to provide EM_AARCH64, I've had to add a conditional check in order to allow cross-compilation on machines that aren't running a bleeding-edge libc-dev.

An architecture should not unconditionally enable 'GENERIC_GPIO' without providing an implementation. In case of arm64, selecting ARCH_WANT_OPTIONAL_GPIOLIB is the right solution, because it lets us enable GPIOLIB when configuring the kernel, and that implicitly turns on GENERIC_GPIO.

The arch_timer driver supports a superset of the functionality of the arm_generic driver, and is not tied to a particular arch. This patch moves arm64 to use the arch_timer driver, gaining additional functionality in doing so, and removes the (now unused) arm_generic driver. Timer-related hooks specific to arm64 are moved into arch/arm64/kernel/time.c.
