Without this patch the linker will generate a section
named .sched.text.1 which is unexpected.
This is because the gcc generated section has "ax" but the
assembler usage of .sched.text lacks the "ax" specifier.
It would be better to have a definition we could use from
assembler code but I did not find a suitable header
file for it.

Fix following warning:
WARNING: arch/x86/kernel/built-in.o(__ksymtab+0x2b0): Section mismatch: reference to .cpuinit.text:arch_register_cpu in '__ksymtab_arch_register_cpu'
Annotating exported symbols are wrong.
Previously the warning were hidden by avoiding the export
in the non HOTPLUG_CPU case but the improved checks in
modpost caught it anyway.
Fix it by removing the __cpuinit annotation and rearrange the

The existing Geode GPIO API only allows for updating one GPIO at once. There
are instances where users want to update multiple GPIOs at once. With the
current API, they are given two choices; either ignore the GPIO API:
outl(0xc000, gpio_base + GPIO_OUTPUT_VAL);
outl(0xc000, gpio_base + GPIO_OUTPUT_ENABLE);
Alternatively, call each GPIO update separately:
geode_gpio_set(14, GPIO_OUTPUT_VAL);
geode_gpio_set(15, GPIO_OUTPUT_VAL);
geode_gpio_set(14, GPIO_OUTPUT_ENABLE);
geode_gpio_set(15, GPIO_OUTPUT_ENABLE);
Neither are desirable. This patch changes the GPIO API to allow for setting
of multiple GPIOs at once; rather than being passed an integer, we pass
a bitmask and provide a translation function. The above code would now
look like this:
geode_gpio_set(geode_gpio(14)|geode_gpio(15), GPIO_OUTPUT_VAL);
geode_gpio_set(geode_gpio(14)|geode_gpio(15), GPIO_OUTPUT_ENABLE);
Since there are no upstream users of the GPIO API yet (afaik), best to
change this now. This also adds a bit of sanity checking; it is no
longer possible to use a GPIO above 28.
Note the semantics of geode_gpio_isset() have changed:
geode_gpio_isset(geode_gpio(3)|geode_gpio(4), ...)
will only return true iff both GPIOs are set.

I found a small bug of NUMA emulation code for x86_64. (CONFIG_NUMA_EMU)
If machine is non-NUMA, find_node_by_addr() should return
NUMA_NO_NODE, but current implementation code returns existent maximum
NUMA node number + 1.
This is not existent NUMA node number.
However, this behaviour does not affect NUMA emulation fortunately, because
acpi_fake_nodes() that is caller of find_node_by_addr() gets pxm
(proximity domain) by node_to_pxm() from non-existent NUMA node number
that was returned by find_node_by_addr().
node_to_pxm() returns PXM_INVAL that means illegal or non-existent
NUMA node number.

when MTRRs are not covering the whole e820 table, we need to trim the
RAM and need to update e820.
reuse some code on 64-bit as well.
here need to add early_get_cap and use it in early_cpu_detect, and move
mtrr_bp_init early.
The code successfully trimmed the memory map on Justin's system:
from:
[ 0.000000] BIOS-e820: 0000000100000000 - 000000022c000000 (usable)
to:
[ 0.000000] modified: 0000000100000000 - 0000000228000000 (usable)
[ 0.000000] modified: 0000000228000000 - 000000022c000000 (reserved)
According to Justin it makes quite a difference:
| When I boot the box without any trimming it acts like a 286 or 386,
| takes about 10 minutes to boot (using raptor disks).

the previous patch in the old RTC driver. It also removes the direct
rtc_interrupt() call from arch/x86/kernel/hpetc.c so that there's finally no
(code) dependency to CONFIG_RTC in arch/x86/kernel/hpet.c.
Because of this, it's possible to compile the drivers/char/rtc.ko driver as
module and still use the HPET emulation functionality. This is also expressed
in Kconfig.

enabled, then interrupts don't work for the rtc-cmos driver which results in
RTC_AIE*, RTC_PIE* and RTC_ALM being unusable. This affects hwclock from
util-linux-ng at least on i386 since that uses RTC_PIE_ON. (For x86-64, a
polling method is used for unknown reasons.)
This patch series now
1. export the functions from arch/x86/kernel/hpet.c that the old char/rtc
driver uses to work around that problem,
2. makes it possible to compile the old rtc driver as module, while still
having CONFIG_HPET_EMULATE_RTC enabled and
3. makes use of the exported functions in (1) in the new rtc-cmos driver.
This patch:
This patch makes the RTC emulation functions in arch/x86/kernel/hpet.c usable
for kernel modules. It
- exports the functions (EXPORT_SYMBOL_GPL()),
- adds an interface to register the interrupt callback function
instead of using only a fixed callback function and
- replaces the rtc_get_rtc_time() function which depends on
CONFIG_RTC with a call to get_rtc_time() which is defined in
include/asm-generic/rtc.h.
The only dependency to CONFIG_RTC is the call to rtc_interrupt() which is
removed by the next patch. After this, there's no (code) dependency of
this functions to CONFIG_RTC=y any more.

Currently in head_32.S there are two ways we test to see if we
are the boot cpu. By looking at %ebx and by looking at the
static variable ready. When changing things around I have
found that it gets tricky to preserve %ebx. So this
patch just switches head.S over to the more reliable
test of always using ready.
Hopefully later we can kill these tests entirely.

The DISCONTIG memory model on x86 32 bit uses a remap allocator early
in boot. The objective is that portions of every node are mapped in to
the kernel virtual area (KVA) in place of ZONE_NORMAL so that node-local
allocations can be made for pgdat and mem_map structures.
With SPARSEMEM, the amount that is set aside is insufficient for all the
mem_maps to be allocated. During the boot process, it falls back to using
the bootmem allocator. This breaks assumptions that SPARSEMEM makes about
the layout of the mem_map in memory and results in a VM_BUG_ON triggering
due to pfn_to_page() returning garbage values.
This patch only enables the remap allocator for use with DISCONTIG.
Without SRAT support, a compile-error occurs because ACPI table parsing
functions are only available in x86-64. This patch also adds no-op stubs
and prints a warning message. What likely needs to be done is sharing
the table parsing functions between 32 and 64 bit if they are
compatible.
