Subject: fs/proc/kcore.c: Pass a pointer to virt_addr_valid()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=9b2d38b4e4a4651ac6efc8ca1a1882c0d4f12937;p=linux.git

fs/proc/kcore.c: Pass a pointer to virt_addr_valid()

The virt_addr_valid() should be passed a pointer, the current
code passing a long unsigned int is just exploiting the
unintentional polymorphism of these calls being implemented
as preprocessor macros.
