[Andrew Morton]

The quilt patch titled
     Subject: fs/procfs: improve PROCMAP_QUERY's compat mode handling
has been removed from the -mm tree.  Its filename was
     fs-procfs-implement-efficient-vma-querying-api-for-proc-pid-maps-fix.patch

This patch was dropped because it was folded into fs-procfs-implement-efficient-vma-querying-api-for-proc-pid-maps.patch

Subject: fs/procfs: improve PROCMAP_QUERY's compat mode handling
Date: Mon, 1 Jul 2024 10:48:05 -0700

Kernel provides compat_ptr_ioctl() wrapper to sanitize pointers for 32-bit
processes on 64-bit host architectures.  Given procfs_procmap_ioctl()
always expects pointer argument, this is exactly what we need.

This has any effect only on 32-bit processes on s390 architecture.
