Yes, and it is crucial to prevent combining,
Remove the eieio() calls in IO functions for PowerPC. While other
architectures permit prefetching, combining, and reordering, the eieio()
calls on PowerPC prevent such optimizations. This has only historical
reasons, because in the early arch/powerpc64 code also readl() had these
eieio() calls, bu

Currently on book3s-hv, the capability KVM_CAP_SPAPR_TCE_VFIO is only
available for KVM Guests running on PowerNV and not for the KVM guests
running on pSeries hypervisors. This prevents a pSeries L2 guest from
leveraging the in-kernel acceleration for H_PUT_TCE_INDIRECT and
H_STUFF_TCE hcalls that

Hi,
I've been toying with the seccomp vs syscall return value problems, and
wonder if something like this approach could give us a simpler alternative.
Basically all the core code uses -errno return value, then we convert it
to the powerpc convention at the last minute when returning.
This seems

Hello,
I believe this patch needs to be reverted for now as it breaks the
user-space build of /tools/testing/radix-tree with:

If hugetlb_cma_only is enabled, we know that hugetlb pages
can only be allocated from CMA. Now that there is an interface
to do early reservations from a CMA area (returning memblock
memory), it can be used to allocate hugetlb pages from CMA.
This also allows for doing pre-HVO on these pages (if e

There are places in signal code that are made more readable by using a
'regs' local variable instead of finding it from the task.

powerpc is one of the "interesting" archs when it comes to system call
error return convention. Rather than returning a -errno, it sets a
condition register bit and returns a +errno. To make matters more
complicated, a new system call instruction was introduced that uses the
-errno convention.
