Nicolas Pitre 3746f02254 ARM: mach-h720x: convert boot_params to atag_offset 
The value used for boot_params in h7201-eval.c is nonsensical, given that
PLAT_PHYS_OFFSET is defined to 0x40000000.  Left unchanged to purposely
break the build to get its maintainer's attention.

Nicolas Pitre 2bb9839e31 ARM: introduce atag_offset to replace boot_params 
The boot_params member of the mdesc structure is used to provide a
default physical address for the ATAG list.  Since this value is fixed
at compile time and sometimes based on constants such as ARCH_PHYS_OFFSET,
it gets in the way of runtime PHYS_OFFSET and CONFIG_ARM_PATCH_PHYS_VIRT
usage.

Let's introduce atag_offset which should contains only the relative
offset from PHYS_OFFSET instead of an absolute value, in preparation
to move all instance of boot_params over to it.

Clemens Ladisch f982f91516 mm: fix wrong vmap address calculations with odd NR_CPUS values 
Commit db64fe0225 ("mm: rewrite vmap layer") introduced code that does
address calculations under the assumption that VMAP_BLOCK_SIZE is a
power of two.  However, this might not be true if CONFIG_NR_CPUS is not
set to a power of two.

Wrong vmap_block index/offset values could lead to memory corruption.
However, this has never been observed in practice (or never been
diagnosed correctly); what caught this was the BUG_ON in vb_alloc() that
checks for inconsistent vmap_block indices.

To fix this, ensure that VMAP_BLOCK_SIZE always is a power of two.
