x86: Introduce ia32_enabled()

Browse source

[ upstream commit 1da5c9bc11 ]

IA32 support on 64bit kernels depends on whether CONFIG_IA32_EMULATION
is selected or not. As it is a compile time option it doesn't
provide the flexibility to have distributions set their own policy for
IA32 support and give the user the flexibility to override it.

As a first step introduce ia32_enabled() which abstracts whether IA32
compat is turned on or off. Upcoming patches will implement
the ability to set IA32 compat state at boot time.
