otg_ulpi_create is defined in drivers/usb/otg/ulpi.c which depends on
CONFIG_USB_ULPI. So protect its usage by the same symbol. Moreover
mxc_ulpi_access_ops needs CONFIG_MXC_ULPI.

Commit 52939c03 (ARM: MX3: fix CPU revision number detection) started
using the CPU's SREV register for revision number detection. This
makes it mandatory to have a valid SPBA0 mapping. Add this to the
global map_io code instead of adding multiple copies for each board.

Pass the frame pointer from the regs of the interrupted path
to dump_trace() while processing the stack trace.
Currently, dump_trace() takes the current bp and starts the
callchain from dump_trace() itself. This is wasteful because
we need to walk through the entire NMI/DEBUG stack before
retrieving the interrupted point.
We can fix that by just using the frame pointer from the
captured regs. It points exactly where we want to start.

Introduce kernel parameter acpi_sleep=sci_force_enable
some laptop requires SCI_EN being set directly on resume,
or else they hung somewhere in the resume code path.
We already have a blacklist for these laptops but we still need
this option, especially when debugging some suspend/resume problems,
in case there are systems that need this workaround and are not yet
in the blacklist.

The wrong address was being used to write the SCIR led regs on remote
hubs. Also, there was an inconsistency between how BIOS and the kernel
indexed these regs. Standardize on using the lower 6 bits of the APIC
ID as the index.
This patch fixes the problem of writing to an errant address to a
cpu # >= 64.

Andrew Morton reported a strange looking kmemcheck warning:
WARNING: kmemcheck: Caught 32-bit read from uninitialized memory (ffff88004fba6c20)

The above printout is missing register dump completely. The
problem here is that the output comes from syslog which doesn't
show KERN_INFO log-level messages. We didn't see this before
because both of us were testing on 32-bit kernels which use the
_default_ log-level.
Fix that up by explicitly using KERN_DEFAULT log-level for
__show_regs() printks.

arch/ia64/kvm/vmm.c:70: error: 'spinlock_t' has no member named 'raw_lock'

spinlock_t type (which changed when ia64 switched to ticket locks). Define
its own vmm_spinlock_t type.

The invlpg prefault optimization breaks Windows 2008 R2 occasionally.
The visible effect is that the invlpg handler instantiates a pte which
is, microseconds later, written with a different gfn by another vcpu.
The OS could have other mechanisms to prevent a present translation from
being used, which the hypervisor is unaware of.
While the documentation states that the cpu is at liberty to prefetch tlb
entries, it looks like this is not heeded, so remove tlb prefetch from
invlpg.

Recently, some distros have started shipping versions of gcc which
default to -march=i686. This breaks building kernels for pre-i686
machines, even if they have been selected in Kconfig, due to the
generation of CMOV instructions.
There isn't enough benefit to try to preserve the generation of these
instructions even when selected, so simply force -march=i386 for the
decompressor when building a 32-bit kernel.

off/online cycle"
This reverts commit 9f15226e75583547aaf542c6be4bdac1060dd425. It's just
wrong, and broke resume for Rafael even on a non-AMD CPU.
As Rafael says:
"... it causes microcode_init_cpu() to be called during resume even for
CPUs for which there's no microcode to apply. That, in turn, results
in executing request_firmware() (on Intel CPUs at least) which doesn't
work at this stage of resume (we have device interrupts disabled, I/O
devices are still suspended and so on).
If I'm not mistaken, the "if (uci->valid)" logic means "if that CPU is
known to us" , so before commit 9f15226e755 microcode_resume_cpu() was
called for all CPUs already in the system during suspend, which was
the right thing to do. The commit changed it so that the CPUs without
microcode to apply are now treated as "unknown", which is not quite
right.
The problem this commit attempted to solve has to be handled
differently."
