Subject: [PATCH] mm: Refactor conversion of pages to bytes macro definitions
Currently there are a multiple files with the following code:
#define K(x) ((x) << (PAGE_SHIFT - 10))
... some code..
#undef K
This is mainly used to print out some memory-related statistics, where X is
given in pages and the macro just converts it to kilobytes. In the future
there is going to be more macros since there are intention to introduce
byte-based memory counters [1]. This could lead to proliferation of
multiple duplicated definition of various macros used to convert a quantity
from one unit to another. Let's try and consolidate such definition in the
mm.h header since currently it's being included in all files which exhibit
this pattern. Also let's rename it to something a bit more verbose.
This patch doesn't introduce any functional changes
