During recent PCI cleanups we noticed that the isa_dma_bridge_buggy
symbol supported by all architectures is actually only used for x86_32.
This patch moves the symbol out of all architectures limiting usage to
only x86_32. This is possible because only x86_32 platforms or quirks

The definition of the pci header function pci_get_legacy_ide_irq is only
used in platforms that support PNP. So many of the architecutres where
it is defined do not use it. This also means we can remove
asm-generic/pci.h as all it provides is a definition of
pci_get_legacy_ide_irq.

In ppc 64, invoke jump_label_init in setup_feature_keys is too late
because static key will be used in subroutine of early_init_devtree.
So we can invoke jump_label_init earlier in early_setup.
We can not move setup_feature_keys backward because its subroutine

There are just 2 functions in nodemask.c, both are thin wrappers around
bitmap API. 1st patch of this series drops dependency on in archrandom.h
lib/nodemask: inline next_node_in() and node_random()

archrandom.h includes to refer ppc_md. This causes
circular header dependency, if generic nodemask.h includes random.h:
In file included from include/linux/cred.h:16,
from include/linux/seq_file.h:13,
from arch/powerpc/include/asm/machdep.h:6,
The functions are pretty thin wrappers around find_bit engine, and
keeping them in c-file prevents compiler from small_const_nbits()
optimization, which must take place for all systems with MAX_NUMNODES
less than BITS_PER_LONG (default is 16 for me).
Moving them to header file doesn't blow up the

Isn't this change also unnecessary?
Initializing to 0 does not affect correctness, or even any kind of
