Except the wrapper was presumably there to map generic code to Linux
code, and the patch doesn't add an include <linux/vmalloc.h> anywhere.
This results in widespread build errrors such as
drivers/staging/r8188eu/core/rtw_mlme.c: In function '_rtw_free_mlme_priv':
drivers/staging/r8188eu/core/rtw_mlme.c:129:17: error: implicit declaration of function 'vfree'
for all architectures where <linux/vmalloc.h> isn't included indirectly.
