d1335fdbad stricter test for max object size 
The previous test with word_bits was sufficient on 32 bit platforms, but
64 bit platforms may set a much smaller value for seL4_MaxUntypedBits in
relation to word_bits.

f563916076 armv8/hyp: Enable FPU in EL0/1 when HYP is on 
The disableFpu() for EL2 traps any FPU instruction to EL2 even
if the FPU is enabled for EL0/1 in CPACR_EL1. For EL2, we
use CPTR_EL2 to enable/disable trapping FPU instructions.
Therefore, we enable FPU for EL0/1 by default so that no additional
exceptions will be generated when we enable FPU access in CPTR_EL2.

87d4f7bf31 arm: Inform user when not using a supported FPU 
This just provides potentially useful information to the user to alert them when they
have configured a kernel without FPU support but are in fact running on a system that
has a usable FPU.

e0281bbccb arm: Make supportsAsyncExceptions always visible in compilation 
This function has no dependencies and can be visible with or without FPU being enabled.
Having it visible will allow for using it to provide better information to the user
when CONFIG_HAVE_FPU is disabled.
