From: Alexandre Belloni
Date: Fri Sep 28 2018 - 05:32:11 EST


gcc 3.3 has been retired for a while, use PTRS_PER_PGD and remove the
asm-offsets.h inclusion.

/*
- * gcc 3.3 and older have trouble determining that PTRS_PER_PGD and PGD_ORDER
- * are constants. So we use the variants from asm-offset.h until that gcc
- * will officially be retired.
- *
* Align swapper_pg_dir in to 64K, allows its address to be loaded
* with a single LUI instruction in the TLB handlers. If we used
* __aligned(64K), its size would get rounded up to the alignment
* size, and waste space. So we place it in its own section and align
* it in the linker script.
