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.

bce62b4e43 Check that TCB object is not larger than necessary 2018-03-23 12:28:54 +11:00

a2a2d9b937 Define tcb_t as half the TCB object size 
A TCB object has two objects inside it, the cnode object and the 'actual tcb object'.
For simplicity of verification we would like the tcb_t portion of the object to also
be size aligned instead of just just being offset by the size of the cnode.

f12d6fdc98 Increase seL4_TCBBits ready for alignment increase 
The alignment of the tcb_t portion of a TCB object is going to be increased, this will
cause the total TCB size to overflow in some cases. This updates the definition of
seL4_TCBBits such that TCBs will be large enough after the alignment change.

f5abc87894 Rename TCB_SIZE_BITS to TCB_CNODE_SIZE_BITS 
This definition is used as the size of the cnode portion of the TCB object (and not the tcb_t)
portion and so this provides a much less confusing name.

315562d35c TX1: error on SMP + cpu utilisation tracking 
TX1 has multiple interrupts for the PMU, one per core. This is
not currently implemented, and is tracked in SELFOUR-1252. It will
work on 1 core.

764b19dc43 cmake: Avoid circular dependencies in prune generation 
This fixes a case where modifying certain kernel files would cause subsequent ninja
invocations to complain of circular dependencies due to the prune generation seeing
an include directory that it was not suppose to.

95a300fe50 x86: Guard call to unmapPage 
This `if` is not strictly necessary as unmapPage will immediately return after failing to
look up the asid but this makes verification easier.

30738188db x86: modeUnmapPage returns whether or not tlb needs invalidation 
Whilst it is always correct to invalidate the TLB even if no page was unampped this
provides a small optimization and makes the modeUnmapPage behaviour mirror the general
arch behaviour
