The idea of this thing is we could save/restore the firmware's
palette when breaking in and out of the firmware prompt.
Only one driver implemented this (atyfb) and it's value is
questionable. If you're just debugging you don't really
care that the characters end up being purple or whatever.
And we can provide better debugging and firmware command
facilities with minimal in-kernel console I/O drivers.

The functions time_before, time_before_eq, time_after, and
time_after_eq are more robust for comparing jiffies against other
values.
So following patch implements usage of the time_after() macro, defined
at linux/jiffies.h, which deals with wrapping correctly

This gives better heuristics for the cost of a multiply (fixed
5 cycles), rather than the 'ultrasparc' setting (variable, and
unpredictable if the second argument is non-constant).
Example code size savings:

The makefile magic for installing the 32-bit vdso images on disk had a

* 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/aegl/linux-2.6:
[IA64] Fix build for sim_defconfig
|

| |
| |

Commit bdc807871d58285737d50dc6163d0feb72cb0dc2 broke the build
for this config because the sim_defconfig selects CONFIG_HZ=250
but include/asm-ia64/param.h has an ifdef for the simulator to
force HZ to 32. So we ended up with a kernel/timeconst.h set
for HZ=250 ... which then failed the check for the right HZ
value and died with:
Drop the #ifdef magic from param.h and make force CONFIG_HZ=32
directly for the simulator.

pageattr-test.c contains a noisy debug printk that people reported.
The condition under which it prints (randomly tapping into a mem_map[]
hole and not being able to c_p_a() there) is valid behavior and not
interesting to report.
Remove it.

Since we may not have a pci_dev for the device we need to access, we can't
use pci_read_config_word. But raw_pci_read is an internal implementation
detail; it's better to use the architected pci_bus_read_config_word
interface. Using PCI_DEVFN instead of a mysterious constant helps
reassure everyone that we really do intend to access device 8.
[ Thanks to Grant Grundler for pointing out to me that this is exactly
what the write immediately above this is doing -- enabling device 8 to
respond to config space cycles.

Grant also says:
"Can you also add a comment which points at the Intel
documentation?
The 'Intel E7320 Memory Controller Hub (MCH) Datasheet' at
http://download.intel.com/design/chipsets/datashts/30300702.pdf
Page 69 documents register F4h (DEVPRES1).
And I just doubled checked that the 0xf4 register value is
restored later in the quirk (obvious when you look at the code
but not from the patch"

WARNING: arch/arm/mach-at91/built-in.o(.text+0xd74): Section mismatch in reference
from the function init_programmable_clock()
to the function .init.text:at91_css_to_clk()
The function init_programmable_clock() references
the function __init at91_css_to_clk().
This is often because init_programmable_clock lacks a __init
annotation or the annotation of at91_css_to_clk is wrong.
In this case the only calls to and from init_programmable_clock()
are from code marked as "__init", so this fix is trivially correct.

According to PXA300/310 and PXA320 Developer manuals,
the ASCR[RDH] "bit needs to be cleared as part of the software
initialization coming out of any reset and coming out of D3".
The latter requirement is addressed by commit
"c4d1fb627ff3072", as for the former (coming out of any reset),
the kernel relies on boot loaders and assumes that RDH bit
is cleared there. Though, not all bootloaders follow the rule
so we have to clear the bit in kernel.
We clear the RDH bit in pxa3xx_init() function since
it is always invoked after any reset. We also preserve D1S, D2S
and D3S bits from being cleared in case we invoke pxa3xx_init()
function not from normal hardware reset (e.g. kexec scenario),
so these bits can be properly referenced later.

We want to allow different implementations of pci_raw_ops for standard
and extended config space on x86. Rather than clutter generic code with
knowledge of this, we make pci_raw_ops private to x86 and use it to
implement the new raw interface -- raw_pci_read() and raw_pci_write().

Thanks to Loic Prylli <loic@myri.com>, who originally proposed
this idea.
Always using legacy configuration mechanism for the legacy config space
and extended mechanism (mmconf) for the extended config space is
a simple and very logical approach. It's supposed to resolve all
known mmconf problems. It still allows per-device quirks (tweaking
dev->cfg_size). It also allows to get rid of mmconf fallback code.
