This patchset originally implemented relocatable kernel support but now

The first patch explains why we need to move the kernel into vmalloc

The second
This is a preparatory patch for relocatable kernel.
The kernel used to be linked at PAGE_OFFSET address and used to be loaded
physically at the beginning of the main memory. Therefore, we could use
the linear mapping for the kernel mapping.
But the relocated kernel base address will be different
This config allows to compile the kernel as PIE and to relocate it at
any virtual address at runtime: this paves the way to KASLR and to 4-level
page table folding at runtime. Runtime relocation is possible since
relocation metadata are embedded into the kernel.
Note that relocating at runtime
Relocating kernel at runtime is done very early in the boot process, so
it is not convenient to check for relocations there and react in case a
relocation was not expected.
Powerpc architecture has a script that allows to check at compile time
for such unexpected relocations: extract the common

This patchset implements sv48 support at runtime. The kernel will try to
boot with 4-level page table and will fallback to 3-level if the HW does not
support it.
There is no need to compare at compile time MAX_EARLY_MAPPING_SIZE value
with PGDIR_SIZE since MAX_EARLY_MAPPING_SIZE is set to 128MB which is less
than PGDIR_SIZE that is equal to 1GB: that allows to simplify early_pmd

CHECK drivers/staging/sm750fb/sm750_hw.c
