The patch titled
Subject: parisc: redefine ATOMIC_INIT and ATOMIC64_INIT like other architectures
has been removed from the -mm tree. Its filename was
parisc-redefine-atomic_init-and-atomic64_init-like-other-architectures.patch
This patch was dropped because it was merged into mainline or a subsystem tree

Subject: parisc: redefine ATOMIC_INIT and ATOMIC64_INIT like other architectures
The following build error occured during a parisc build with
swap-over-NFS patches applied.
net/core/sock.c:274:36: error: initializer element is not constant
net/core/sock.c:274:36: error: (near initialization for 'memalloc_socks')
net/core/sock.c:274:36: error: initializer element is not constant
It's not obvious but this is due to how ATOMIC_INIT is defined on parisc.
It should affect any user of STATIC_KEY_INIT_FALSE on that platform.
This patch makes the definition of ATOMIC_INIT on parisc to look like
other arches definition.
Apparently due to gcc creating a temporary. John said "Parisc is a callee
copies architecture. Thus, a structure passed as an argument may be
copied to a temporary. This has been a source of numerous bugs as the
majority of architectures do it the other way round."
