Patch series "mm: Coccinelle-driven cleanups across memory management
code", v4.

This patch series contains three minor cleanups identified by Coccinelle
scripts under scripts/coccinelle/misc/:

  * Use ALIGN() to compute the next hugepage boundary instead of the
    open-coded expression and use min() macro to improve readability.
  * Use the %pe printk format specifier for PTR_ERR() reporting
    in vmscan.c and zswap.c
Found using:
  make coccicheck MODE=report M=mm/


This patch (of 3):

Replace hugepage boundary computation with ALIGN() helper instead of an
open coded expression.  This helps to improves code readability.

This was flagged by Coccinelle (misc/minmax.cocci) as an opportunity to
use min(), after which the boundary computation was updated following
review suggestions.

Found by: make coccicheck MODE=report M=mm/
No functional change intended.
