The return value of kvmppc_gse_put_buff_info() is not assigned to 'rc' and
'rc' is uninitialized at this point.
So the error handling can not work.
Assign the expected value to 'rc' to fix the issue.

Callback arch_vtime_task_switch() is only defined when
CONFIG_VIRT_CPU_ACCOUNTING_NATIVE is selected. Yet, the
function prototype forward declaration is present for
CONFIG_VIRT_CPU_ACCOUNTING_GEN variant. Remove it.

There is no architecture-specific code or data left
that generic needs to know about.
Thus, avoid the inclusion of header.

The generic vtime_task_switch() implementation gets built only
if __ARCH_HAS_VTIME_TASK_SWITCH is not defined, but requires an
architecture to implement arch_vtime_task_switch() callback at
the same time, which is confusing.
Further, arch_vtime_task_switch() is implemented for 32-bit PowerPC

Hi all,
Please find a small cleanup to vtime_task_switch() wiring.
I split it into smaller patches to allow separate PowerPC
vs s390 reviews. Otherwise patches 2+3 and 4+5 could have
been merged.
I tested it on s390 and compile-tested it on 32- and 64-bit
PowerPC and few other major architectures
update_timer_sys() and update_timer_mcck() are inlines used for
CPU time accounting from the interrupt and machine-check handlers.
These routines are specific to s390 architecture, but declared
via header, which in turn inludes .
Avoid the extra loop and include header directly.

Architectures like powerpc add debug checks to ensure we find only devmap
PUD pte entries. These debug checks are only done with CONFIG_DEBUG_VM.
This patch marks the ptes used for PUD advanced test devmap pte entries
so that we don't hit on debug checks on architecture like ppc64 as
below.
