x86, ioapic: Document another case when level irq is seen as an edge
In the case when cpu goes offline, fixup_irqs() will forward any
unhandled interrupt on the offlined cpu to the new cpu
destination that is handling the corresponding interrupt. This
interrupt forwarding is done via IPI's. Hence, in this case also
level-triggered io-apic interrupt will be seen as an edge
interrupt in the cpu's APIC IRR.
Document this scenario in the code which handles this case by doing
an explicit EOI to the io-apic to clear remote IRR of the io-apic RTE.

IO-APIC versions below 0x20 don't support EOI register.
Some of the Intel ICH Specs (ICH2 to ICH5) documents the io-apic
version as 0x2. This is an error with documentation and these
ICH chips use io-apic's of version 0x20 and indeed has a working
EOI register for the io-apic.
Fix the EOI register detection mechanism to check for version
0x20 and beyond.
And also, a platform can potentially have io-apic's with
different versions. Make the EOI register check per io-apic.

x86, io-apic: Move the effort of clearing remoteIRR explicitly before migrating the irq
When the level-triggered interrupt is seen as an edge interrupt,
we try to clear the remoteIRR explicitly (using either an
io-apic eoi register when present or through the idea of
changing trigger mode of the io-apic RTE to edge and then back
to level). But this explicit try also needs to happen before we
try to migrate the irq. Otherwise irq migration attempt will
fail anyhow, as it postpones the irq migration to a later
attempt when it sees the remoteIRR in the io-apic RTE still set.

Retrigger the irq at the new destination if any interrupt has arrived

For IO-APIC level triggered interrupts, this retrigger IPI will
appear as an edge interrupt. ack_apic_level() will detect this
condition and IO-APIC RTE's remoteIRR is cleared using directed
EOI(using IO-APIC EOI register) on Intel platforms and for
others it uses the existing mask+edge logic followed by
unmask+level.
We can also remove mdelay() and then send spuriuous interrupts
to new cpu targets for all the irqs that were handled previously
by this cpu that is going offline. While it works, I have seen
spurious interrupt messages (nothing wrong but still annoying
messages during cpu offline, which can be seen during

ARM: force dcache flush if dcache_dirty bit set
On ARM, update_mmu_cache() does dcache flush for a page only if
it has a kernel mapping (page_mapping(page) != NULL). The correct
behavior would be to force the flush based on dcache_dirty bit only.
One of the cases where present logic would be a problem is when
a RAM based block device[1] is used as a swap disk. In this case,
we would have in-memory data corruption as shown in steps below:
do_swap_page()
{
- Allocate a new page (if not already in swap cache)
- Issue read from swap disk
- Block driver issues flush_dcache_page()
- flush_dcache_page() simply sets PG_dcache_dirty bit and does not
actually issue a flush since this page has no user space mapping yet.
- Now, if swap disk is almost full, this newly read page is removed
from swap cache and corrsponding swap slot is freed.
- Map this page anonymously in user space.
- update_mmu_cache()
- Since this page does not have kernel mapping (its not in page/swap
cache and is mapped anonymously), it does not issue dcache flush
even if dcache_dirty bit is set by flush_dcache_page() above.
<user now gets stale data since dcache was never flushed>
}
Same problem exists on mips too.

Having this as a device_initcall() means that some real device drivers
can actually initialise _before_ the quirks are run, which is wrong.
We want it to run _before_ device_initcall(), but _after_ fs_initcall(),
since some arch-specific PCI initialisation like pcibios_assign_resources()
is done at fs_initcall().
We could use rootfs_initcall() but I actually want to use that for the

We simply can't do the USB handoff at FIXUP_HEADER time, since it will
often require us to have valid IO mappings etc. But that in turn
requires a whole different approach, not this trivial one-liner.
Maybe we could teach all the USB quirk handoff handlers to only do the
quirk if the device has all its registers set up (since if it isn't
initialized, it's unlikely to be active), but regardless that will need
a whole lot more code than just saying "let's do it really early".
The proper fix is almost certainly to just leave the legacy IOMMU
mappings active until after all devices have been initialized.

It caused following issues:
- On architectures where ARCH= setting is used to select between
32 and 64 bit this was no longer possible without "make mrproper"
- If ARCH was changed then kbuild refused to run "make mrproper"
because ARCH had changed
- When CROSS_COMPILE was changed people were asked to run "make mrproper"
but kbuild refused to run "make mrproper" because CROSS_COMPILE changed.
- Spaces in CROSS_COMPILE was not 'supported'
- If an non-existing ARCH= was used kbuild could get stuck
Lessons learned:
. Despite being simple and straghtforward people uses very different
approaches when building the kernel.
. CROSS_COMPILE is sometimes used for ccache despite cache being
only a CC frontend so one would have expected CC to be
used for this purpose.
. And obviously this was not tested widely enough.

kbuild: Fix size_append issue for bzip2/lzma kernel
The Makefile.lib will call "echo -ne" to append uncompressed kernel size to
bzip2/lzma kernel image.
The "echo" here depends on the shell that /bin/sh pointing to.
On Ubuntu system, the /bin/sh is pointing to dash, which does not support
"echo -e" at all. Use /bin/echo instead of shell echo should always be safe.

kbuild: fix the binrpm-pkg target to work with KBUILD_OUTPUT set
The binrpm-pkg target (binary RPM only) fails when called with
KBUILD_OUTPUT set. This patch makes it work.
For the rpm-pkg target (source + binary RPM), building with
KBUILD_OUTPUT set is not possible and also not needed as the
actual build is done in a temporary directory anyway, so check
that KBUILD_OUTPUT is not set in that case to avoid later errors.

and two internal PLLs to derive all the internal clocks. Many of these
internal clocks can be stopped to save power.
This introduces a "parent" hierarchy for the clocks so that the users

The "parent" for the video clock can either be one of the PLL outputs
