Nicolas Pitre authored Jul 05, 2011



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.

ARM: introduce atag_offset to replace boot_params · 2bb9839e

Nicolas Pitre authored Jul 05, 2011



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.

mm: fix wrong vmap address calculations with odd NR_CPUS values · f982f915

Clemens Ladisch authored Jun 21, 2011

Commit db64fe02 ("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.
