apic_noop is used to provide dummy apic functions. It's installed
when the CPU has no APIC or when the APIC is disabled on the kernel

The apic_noop implementation of apic_write() warns when the CPU has
an APIC or when the APIC is not disabled.
That's bogus. The warning should only happen when the CPU has an
APIC _AND_ the APIC is not disabled. apic_noop.apic_read() has the

Git commit ea43546750 changed the
definition of atomic_t and atomic64_t for s390 by adding the volatile
modifier to the counter field. This has an unfortunate side effect
with newer versions of the gcc. The typeof operator now picks up the
volatile modifier from the expression. This causes the compiler to
think that it has to store the two temporary variable old_val and
new_val in the __CS_LOOP for the different atomic operations to the
stack as the variables are now volatile. Both stores are superfluous.
The hack to replace typeof(ptr->counter) with int in __CS_LOOP and
and long long in __CSG_LOOP avoids the two stores. A better solution
would be to drop the volatile from the counter field of the atomic_t
and atomic64_t definition. But that is a touchy subject ..

with recent changes to do_exception(), e.g. performance counters. This

directly, eliminating the redundancy. A new parameter is added to

Introduce user_mode to replace the two variables switch_amode and
s390_noexec. There are three valid combinations of the old values:
1) switch_amode == 0 && s390_noexec == 0
2) switch_amode == 1 && s390_noexec == 0
3) switch_amode == 1 && s390_noexec == 1
They get replaced by
1) user_mode == HOME_SPACE_MODE
2) user_mode == PRIMARY_SPACE_MODE
3) user_mode == SECONDARY_SPACE_MODE
The new kernel parameter user_mode=[primary,secondary,home] lets
you choose the address space mode the user space processes should
use. In addition the CONFIG_S390_SWITCH_AMODE config option
is removed.

PM_SUSPEND, PM_RESUME and machine_is_h3xxx() are not used anywhere in
kernel (checked with git grep), so it's safe to remove them.

No point calling sa1100_register_uart_fns early - these aren't
used until late in the boot sequence. Also convert to gpiolib
support.

"ARCH" can be just about anything, so we shouldn't end up
with UTS_MACHINE of "sparc" in a 64-bit kernel build just
because someone set the personality using 'sparc32' or
similar. CONFIG_SPARC64 drives the compilation and
therefore provides the definitive value, not "ARCH".
This mirrors commit 8c6531f7a9
(x86: correctly set UTS_MACHINE for "make ARCH=x86")

hang when rebooting unless reboot=b was specified. Their dmidecode
didn't contain descriptive System Information for Manufacturer or
