Subject: x86: increase max physical memory size of 64-bit
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8434e73d9ec2aeaa86389e362b960ffba5edd9c9;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

x86: increase max physical memory size of 64-bit

Increase the maximum physical address size of x86_64 system
to 44-bits. This is in preparation for future chips that
support larger physical memory sizes.
