Subject: [PATCH] BACKPORT: Linux 5.8 compat: __vmalloc()
|
||||
MIME-Version: 1.0
|
||||
Content-Type: text/plain; charset=UTF-8
|
||||
Content-Transfer-Encoding: 8bit
|
||||
|
||||
The `pgprot` argument has been removed from `__vmalloc` in Linux 5.8,
|
||||
being `PAGE_KERNEL` always now [1].
|
||||
|
||||
Detect this during configure and define a wrapper for older kernels.

||||
