sparc64: Don't restrict fp regs for no-fault loads
The function handle_ldf_stq() deals with no-fault ASI
loads and stores, but restricts fp registers to quad
word regs (ie, %f0, %f4 etc). This is valid for the
STQ case, but unnecessarily restricts loads, which
may be single precision, double, or quad. This results
in SIGFPE being raised for this instruction when the
source address is invalid:
ldda [%g1] ASI_PNF, %f2
but not for this one:
ldda [%g1] ASI_PNF, %f4
The validation check for quad register is moved to
within the STQ block so that loads are not affected
by the check.
An additional problem is that the calculation for freg
is incorrect when a single precision load is being
handled. This causes %f1 to be seen as %f32 etc,
and the incorrect register ends up being overwritten.
This code sequence demonstrates the problem:
ldd [%g1], %f32 ! g1 = valid address
lda [%i3] ASI_PNF, %f1 ! i3 = invalid address
std %f32, [%g1]
This is corrected by basing the freg calculation on
the load size.

KVM: arm/arm64: Optimize away redundant LR tracking
Currently we use vgic_irq_lr_map in order to track which LRs hold which
IRQs, and lr_used bitmap in order to track which LRs are used or free.
vgic_irq_lr_map is actually used only for piggy-back optimization, and
can be easily replaced by iteration over lr_used. This is good because in
future, when LPI support is introduced, number of IRQs will grow up to at
least 16384, while numbers from 1024 to 8192 are never going to be used.
This would be a huge memory waste.
In its turn, lr_used is also completely redundant since ae705930fca6322600690df9dc1c7d0516145a93 ("arm/arm64: KVM: Keep elrsr/aisr
in sync with software model"), because together with lr_used we also update
elrsr. This allows to easily replace lr_used with elrsr, inverting all
conditions (because in elrsr '1' means 'free').

ARC: [arcompact] Handle bus error from userspace as Interrupt not exception
Bus errors from userspace on ARCompact based cores are handled by core
as a high priority L2 interrupt but current code treated it as interrupt
Handling an interrupt like exception is certainly not going to go unnoticed.
(and it worked so far as we never saw a Bus error from userspace until
IPPK guys tested a DDR controller with ECC error detection etc hence
needed to explicitly trigger/handle such errors)
- So move mem_service exception handler from common code into ARCv2 code.
- In ARCompact code, define mem_service as L2 interrupt handler which
just drops down to pure kernel mode and goes of to enqueue SIGBUS
