The -T/--thread option is supported only on --stdio mode (at least for
now). So enforce the tty output if the option was requested.

It seems there's no reason to suppress per-thread event stat by -T
option when -s or -p option is used. Make it work with those options.

Since the ISA irqs are in a single block, use ISA_IRQ_VECTOR(irq)
instead of individual macros.

Hi everyone,
This patch series introduces basic kernel support for Allwinner's H3 SoC,
mainly basic clocks and pinctrl. It also adds interrupts, timers,
watchdog, RTC, dmaengine, MMC and UARTs, which are mostly compatible to

Bool initializations should use true and false. Bool tests don't need
comparisons. Based on contributions from Joe Perches, Rusty Russell
and Bruce W Allan.
The semantic patch that makes this change is available
in scripts/coccinelle/misc/boolinit.cocci.

Extend the testcase to catch a signedness bug in the arm64 JIT:

This is useful to ensure other JITs won't have a similar bug.
