[PATCH] x86/fixmap: Decouple KMAP_LOCAL from PCI_MMCONFIG

From: ira . weiny
Date: Sat Oct 01 2022 - 20:05:05 EST


From: Ira Weiny <ira.weiny@xxxxxxxxx>

In commit 14df32670291 ("x86: Support kmap_local() forced debugging")
FIX_PCIE_MCFG became dependent on KMAP_LOCAL. This works because
CONFIG_KMAP_LOCAL depends on CONFIG_X86_32 which the commit changed.

config X86_32
def_bool y
depends on !64BIT
...
select KMAP_LOCAL
...

However, there is no direct relationship between the two. Adjust the
conditionals to make them independent of each other.
