This adds an option to remove vm86 support under CONFIG_EMBEDDED. Saves
about 5k.This version eliminates most of the #ifdefs of the previous version and
instead uses function stubs in vm86.h. Also, release_vm86_irqs is moved
from asm-i386/irq.h to a more appropriate home in vm86.h so that the stubs
can live together.$ size vmlinux-baseline vmlinux-novm86

Use first_cpu(cpu_possible_map) for the single-thread workqueue case. We
used to hardcode 0, but that broke on systems where !cpu_possible(0) when
workqueue_struct->cpu_workqueue_struct was changed from a static array to
alloc_percpu.Commit id bce61dd49d6ba7799be2de17c772e4c701558f14 ("Fix hardcoded cpu=0 in
workqueue for per_cpu_ptr() calls") fixed that for Ben's funky sparc64
system, but it regressed my Power5. Offlining cpu 0 oopses upon the next
call to queue_work for a single-thread workqueue, because now we try to
manipulate per_cpu_ptr(wq->cpu_wq, 1), which is uninitialized.So we need to establish an unchanging "slot" for single-thread workqueues
which will have a valid percpu allocation. Since alloc_percpu keys off of
cpu_possible_map, which must not change after initialization, make this
slot == first_cpu(cpu_possible_map).Signed-off-by: Nathan Lynch

Since version 4.1 the gcc is warning about ignored attributes. This patch is
using the equivalent attribute on the struct instead of on each of the
structure or union members.GCC Manual:
"Specifying Attributes of Typespacked
This attribute, attached to struct or union type definition, specifies
that
each member of the structure or union is placed to minimize the memory
required. When attached to an enum definition, it indicates that the
smallest integral type should be used.Specifying this attribute for struct and union types is equivalent to
specifying the packed attribute on each of the structure or union
members."Signed-off-by: Jan Blunck

If a 9pfs server crashes, v9fs_fd_close() is called. Subsequently, in
cleaning up by performing a umount() on the FS that was provided by this
server v9fs_fd_close() is called again, and uses the old, freed valus of
trans->priv. This patch ensures that trans->priv can be freed only once,
otherwise this function bails early.Signed-off-by: Michal Ostrowski
