Evaluating cc-name invokes the compiler every time even when you are
not compiling anything, like 'make help'. This is not efficient.
The compiler type has been already detected in the Kconfig stage.
Use CONFIG_CC_IS_CLANG, instead.

I started out this series trying to make sysrq work over the serial
console on qcom_geni_serial, then fell into a rat's nest.
To solve the deadlock I faced when enabling sysrq I tried to borrow
code from '8250_port.c' which avoided grabbing the port lock in
console_write(). ...but since these

On pseries systems, performing a partition migration can result in
altering the nodes a CPU is assigned to on the destination system. For
exampl, pre-migration on the source system CPUs are in node 1 and 3,
post-migration on the destination system CPUs are in nodes 2 and 3.

Nobody used those flags. Anyone who wanted to temporarily turn on
interrupts just did
In kgdb_roundup_cpus() we've got code that looks like:
local_irq_enable();
smp_call_function(kgdb_call_nmi_hook, NULL, 0);
local_irq_disable();
In certain cases when we drop into kgdb (like with sysrq-g on a serial

Use TEST_GEN_PROGS and don't redefine all, this makes the out-of-tree
build work. We need to move the extra dependencies below the include
of lib.mk, because it adds the $(OUTPUT) prefix if it's defined.
We can also drop the clean rule, lib.mk does it for us.
