Problem:
Will have "PC=0, LR=0" issue when try to
show active cpu stacks via sysrq
Solution:
Save the addr of current interrupted task's context to the
interrupt stack first, so that we can easily obtain pt_regs
later

Problem:
printk_prefix() passes NULL buf to print_time() to get the length of
the time prefix; when printk times are enable, the current code just
return "snprint(NULL, 0, "[%5lu.000000]", (unsigned long)ts)"
but in the SMP case, we add cpu core id at the end of time prefix, the
format is "[%5lu, %06lu@%d]", this gives a wrong size(shorter).
this will make buf get out of boundary, when run dmesg.
Solution:
replace [%5lu.000000] with [%5lu.000000@0]

Problem:
For the previous Amlogic CPU series(before TXLX), the CPU booting vector
locates at physical address starting from 0x00. To avoid influencing cpu
booting procedure, we have to reserve the first 1MB physical memory. But
it has changed since TXLX, the normal text section can safely use 0~1M
physical address. So it's no need to reserve the first 1MB in DTS.
Solution:
Change the starting address of usable memory from 0x100000 to 0x0 for CPU
series coming after TXLX.
