The quilt patch titled
     Subject: tools/mm/page-types: fix ternary operator precedence in sigbus handler

This patch was dropped because it was merged into the mm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: tools/mm/page-types: fix ternary operator precedence in sigbus handler
Date: Wed, 13 May 2026 10:21:17 +0800

The ternary operator (?:) has lower precedence than addition (+), so the
expression `off + sigbus_addr ?  sigbus_addr - ptr : 0` was parsed as
`(off + sigbus_addr) ?  (sigbus_addr - ptr) : 0` rather than the intended
`off + (sigbus_addr ?  sigbus_addr - ptr : 0)`.  Add explicit parentheses
to ensure the correct evaluation order.
