Store the old environment in a local context so another temporary address
environment can be selected. This can happen especially when a process
is being loaded (the new process's mappings are temporarily instantiated)
and and interrupt occurs.
When l2cc is already in disable state, performing a disable operation
again will flush incorrect cache data to memory

Invalidate operations at DDI0246H_l2c310_r3p3_trm:
If there is a stale entry in the L2 cache, the system enables the invalidation of
the L1 cache. But before the controller invalidates the L2 cache, it allocates a
line from the L2 cache to an L1 cache.
The robust code sequence for invalidation with a non-exclusive cache arrangement is:
1. InvalLevel2 Address ; forces the address out past level 2
2. CACHE SYNC ; Ensures completion of the L2 inval
3. InvalLevel1 Address ; This is broadcast within the cluster
4. DSB ; Ensure completion of the inval as far as Level 2.
This sequence ensures that, if there is an allocation to L1 after the L1 invalidation, the data
picked up is the new data and not stale data from the L2

ROM symbols provided by linker are placeholders for addresses
and not a pure addresses, so we need to read data pointed by
ROM symbols instead of using those as pure addresses.

If CONFIG_MM_CUSTOMIZE_MANAGER enabled on sim, malloc/mmap is bypassed to glibc, so the memory allocated without execution permisson.
For this case, CONFIG_ARCH_USE_TEXT_HEAP can be used.

In smp when cpu0 calls up_cpu_resume to release the cpu1 lock, another locked cpu1 did not execute immediately,
and soon cpu0 called up_cpu_resume again, now cpu1 unable to respond to the interrupt at this time, resulting in a deadlock.
Our solution is to restore cpu1 execution from asynchronous to synchronous to ensure that cpu1 is restored.

280 | cond = (g_parm[COND_INDEX] && strlen(g_parm[COND_INDEX]) > 0);
