Subject: Move VMSPLIT_3G to 'userspace_hardening'
X-Git-Tag: v0.5.5~9
X-Git-Url: https://jxself.org/git/?a=commitdiff_plain;h=b06c8cd92a94b374ba56a031af6f8a3cc5faefa9;p=kconfig-hardened-check.git

Move VMSPLIT_3G to 'userspace_hardening'

CONFIG_VMSPLIT_3G=y is for maximal userspace memory area and maximal ASLR.

It works both for ARM and X86_32.
