The patch titled
vmalloc: add const to void* parameters
has been removed from the -mm tree. Its filename was
vmalloc-add-const-to-void-parameters.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
Subject: vmalloc: add const to void* parameters
From: Christoph Lameter <clameter@xxxxxxx>
Make vmalloc functions work the same way as kfree() and friends that
take a const void * argument.
[akpm@xxxxxxxxxxxxxxxxxxxx: fix consts, coding-style]
