dfcec5595f libchip/network/if_fxp.c: do not use rtems_interrupt_disable. 
The single write to memory or ioport output are mostly
atomic operations already. The proper memory synchronization barrier
should be used around them to guarantee ordering (sync or eieio
on PowerPC for example) but because I have not found settable
portable primitive only compiler barrier is used.
It should be enough on x86 because the externally visible order
should be/is guaranteed to be preserved on x86 architecture.

20625a581d bsps/i386: use Pentimum instructions for pc586 and pc686 builds. 
When GCC option -march is not specifies i386-rtems toolchain
defaults to i386 architecture instruction set. It does not
provide atomic instructions which results in really inefficient
atomic_fetch_or even on UP build.

SMP build is broken with i386 set because libatomic and GCC
generate infinite loop for __atomic_fetch_add_4 used
in rtems_interrupt_lock_acquire

__atomic_fetch_add_4:
    push   %ebp
    mov    %esp,%ebp
    movl   $0x5,0x10(%ebp)
    pop    %ebp
    jmp    __atomic_fetch_add_4

facebbb28e bsps/i386: Separate variable for i8259 IRQs disable due to in progress state. 
The global state of enabled and disabled interrupts has to hold
interrupts really disabled by drivers and system. If the state is
combined with interrupts temporarily disabled because they are
processed at given time then it is impossible to maintain state
by interrupt handlers in drivers.

8714684129 score/arm: Correct logic to select 64 byte cache line maximum size for Cortex-A. 
The use of actual cache line max bytes and minimum required alignment
in architecture but not-BSP dependent code could be problematic
because there exists even ARM instruction set implementations
with 128 byte line length and real maximum can be quite problematic
to say. But actually supported ARM BSPs should be OK with these values.

89b4a5cc5f libdl/rtl-obj.c: synchronize cache should not depend on CPU_CACHE_LINE_BYTES. 
Use of rtems_cache_get_maximal_line_size() is more descriptive
choice. The min/max data/instruction cache line size is not critical
there, value is used for optimization only to use single operation
for directly following sections.
