Subject: x86/pkeys: Remove __arch_set_user_pkey_access() declaration
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5a0893088a20252cc268cbeabb25e883c2b6f94f;p=linux.git
x86/pkeys: Remove __arch_set_user_pkey_access() declaration
In the x86 code __arch_set_user_pkey_access() is not used and is not
defined.
Remove the dead declaration.
