kernel/arch/nds32/include/asm/pgtable.h, branch linux-5.1.yHosts the 0x221E linux distro kernel.https://universe.0xinfinity.dev/distro/kernel/atom?h=linux-5.1.y2018-11-02T07:31:52Zmm: make the __PAGETABLE_PxD_FOLDED defines non-empty2018-11-02T07:31:52ZMartin Schwidefskyschwidefsky@de.ibm.com2018-10-31T11:11:48Zurn:sha1:a8874e7e8a8896f2b6c641f4b8e2473eafd35204
Change the currently empty defines for __PAGETABLE_PMD_FOLDED,
__PAGETABLE_PUD_FOLDED and __PAGETABLE_P4D_FOLDED to return 1.
This makes it possible to use __is_defined() to test if the
preprocessor define exists.
