Subject: ARM: 7947/1: Make pgtbl macro more robust
X-Git-Tag: v3.14-rc1~58^2~1^2~2
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=2ab4e8c06dc084c1bba8c8edfa1b33424c16d336;p=linux.git

ARM: 7947/1: Make pgtbl macro more robust

The pgtbl macro couldn't handle the specific
(TEXT_OFFSET - PG_DIR_SIZE) value that the combination of
MSM platforms and LPAE created:

head.S:163: Error: invalid constant (203000) after fixup

Regardless of whether this combination of configuration options
will work on currently support platforms at run time, make it
at least assemble properly.
