Virtex FPGA designs have two serial port logic cores to choose from; the
simple uartlite, and the full featured uart16550. Both cores are in
common use so the defconfig should support both of them. Currently
only console on uartlite is supported in the defconfig. This patch adds
console support for the 16550 core.
The Virtex reference designs do not work without this patch.

Defining flash partition table in platform code is deprecated, and due to
recent changes linkstation and storcenter do not compile any more with
their default configurations because of undefined references to
physmap_set_partitions(). Instead of fixing them by using the correct
kernel configuration macro in preprocessor conditional, remove partition
table definitions altogether. Instead add support for partition definition
on the command-line and in device tree to the default configurations.

Impact: fix race+crash in mmiotrace
The list manipulation in remove_kmmio_fault_pages() was broken. If more
than one consecutive kmmio_fault_page was re-added during the grace
period between unregister_kmmio_probe() and remove_kmmio_fault_pages(),
the list manipulation failed to remove pages from the release list.
After a second grace period the pages get into rcu_free_kmmio_fault_pages()
and raise a BUG_ON() kernel crash.
The list manipulation is fixed to properly remove pages from the release
list.
This bug has been present from the very beginning of mmiotrace in the
mainline kernel. It was introduced in 0fd0e3da ("x86: mmiotrace full
patch, preview 1");
An urgent fix for Linus. Tested by Stuart (on 32-bit) and Pekka
(on amd and intel 64-bit systems, nouveau and nvidia proprietary).

This reverts commit e088e4c9cdb618675874becb91b2fd581ee707e6.
Removing the sysfs interface for p4-clockmod was flagged as a
regression in bug 12826.
Course of action:
- Find out the remaining causes of overheating, and fix them
if possible. ACPI should be doing the right thing automatically.
If it isn't, we need to fix that.
- mark p4-clockmod ui as deprecated
- try again with the removal in six months.
It's not really feasible to printk about the deprecation, because
it needs to happen at all the sysfs entry points, which means adding
a lot of strcmp("p4-clockmod".. calls to the core, which.. bleuch.

The following patch enables SMC911x support to work on the OMAP LDP
board. Although the SMC911x driver will eventually be obsoleted, the
smsc911x patches are rather invasive for the -rc kernels.
Rather than risk destablising smsc911x, this simpler patch is preferred
to allow the network interface to work.

Impact: remove lots of lguest boot WARN_ON() when CONFIG_SPARSE_IRQ=y
We now need to call irq_to_desc_alloc_cpu() before
set_irq_chip_and_handler_name(), but we can't do that from init_IRQ (no
kmalloc available).
So do it as we use interrupts instead. Also means we only alloc for
irqs we use, which was the intent of CONFIG_SPARSE_IRQ anyway.

Impact: fix lguest boot crash on modern Intel machines
The code in early_init_intel does:
if (c->x86 > 6 || (c->x86 == 6 && c->x86_model >= 0xd)) {
u64 misc_enable;
rdmsrl(MSR_IA32_MISC_ENABLE, misc_enable);
And that rdmsr faults (not allowed from non-0 PL). We can get around
this by mugging the family ID part of the cpuid. 5 seems like a good
number.
Of course, this is a hack (how very lguest!). We could just indicate
that we don't support MSRs, or implement lguest_rdmst.

ds_write_config() can write the BTS as well as the PEBS part of
the DS config. ds_request_pebs() passes the wrong qualifier, which
results in the wrong configuration to be written.

In case a ptraced task is reaped (while the tracer is still attached),
ds_exit_thread() is called before ptrace_exit(). The latter will
release the bts_tracer and remove the thread's ds_ctx.
The former will WARN() if the context is not NULL.
Oleg Nesterov submitted patches that move ptrace_exit() before
exit_thread() and thus reverse the order of the above calls.
Remove the bad warning. I will add it again when Oleg's changes are in.

Impact: fix math-emu related crash while using GDB/ptrace
init_fpu() calls finit to initialize a task's xstate, while finit always
works on the current task. If we use PTRACE_GETFPREGS on another
process and both processes did not already use floating point, we get
a null pointer exception in finit.
This patch creates a new function finit_task that takes a task_struct
parameter. finit becomes a wrapper that simply calls finit_task with
current. On the plus side this avoids many calls to get_current which
would each resolve to an inline assembler mov instruction.
An empty finit_task has been added to i387.h to avoid linker errors in
case the compiler still emits the call in init_fpu when
CONFIG_MATH_EMULATION is not defined.
The declaration of finit in i387.h has been removed as the remaining
code using this function gets its prototype from fpu_proto.h.

Impact: Fix boot failure on EFI system with large runtime memory range
Brian Maly reported that some EFI system with large runtime memory
range can not boot. Because the FIX_MAP used to map runtime memory
range is smaller than run time memory range.
This patch fixes this issue by re-implement efi_ioremap() with
init_memory_mapping().

Impact: reactivate DMI quirks on EFI hardware
DMI tables are loaded by EFI, so the dmi calls must happen after
efi_init() and not before.
Currently Apple hardware uses DMI to determine the framebuffer mappings
for efifb. Without DMI working you also have no video on MacBook Pro.
This patch resolves the DMI issue for EFI hardware (DMI is now properly
detected at boot), and additionally efifb now loads on Apple hardware
(i.e. video works).

instruction on bf561 after soft bp is hit
Run IFLUSH twice to avoid loading wrong instruction
after invalidating icache and following sequence is met.
1) The one instruction address is cached in the icache.
2) This instruction in SDRAM is changed.
3) IFLASH[P0] is executed only once in lackfin_icache_flush_range().
4) This instruction is executed again, but not the changed new one.

IMHO the setting should depend on ANOMALY_05000305 which is about the
availability of the bit, not ANOMALY_05000265 which only describes the
SPORT sensitivity to noise (checked for BF561 only, though).
If that's not true for other BF variants, maybe the definition of
ANOMALY_05000265 for BF561 should be changed to '(1)' instead.

I have a system where UART0 is configured with hardware flow control, but UART1
doesn't have it enabled. Attempting to access UART1 in this configuration
results in the following error in dmesg:

This is because the #ifdef's in bfin_serial_5xx.h are messed up. More
specifically, they add/remove the uart_{rts,cts}_pin fields in
bfin_serial_resources based on whether the particular port has rts/cts enabled,
as opposed to when either port has it enabled.
This patch fixed this.
