-Subject: bounds: support non-power-of-two CONFIG_NR_CPUS
-
-From: Matthew Wilcox (Oracle) <willy@infradead.org>
-
-commit f2d5dcb48f7ba9e3ff249d58fc1fa963d374e66a upstream.
-
-ilog2() rounds down, so for example when PowerPC 85xx sets CONFIG_NR_CPUS
-to 24, we will only allocate 4 bits to store the number of CPUs instead of
-5.  Use bits_per() instead, which rounds up.  Found by code inspection.
-The effect of this would probably be a misaccounting when doing NUMA
-balancing, so to a user, it would only be a performance penalty.  The
-effects may be more wide-spread; it's hard to tell.
