While Intel's spec is not that clear here, latest changes to Linux' HPET
code (commit c23e253e67c9d8a91a0ffa33c1f571a17f0a2403, "x86: hpet: stop
HPET_COUNTER when programming periodic mode") strongly suggest that
HPET_TN_SETVAL rather means: Set _both_ the comparator value and
register.

With this patch applied, I'm again able to boot 2.6.30-rc kernels as
they no longer panic like this (which was due to the comparator
register remaining 0):

Fix (more or less) spurious guest boot failures due to corrupted cpuid
states. The reason was insufficient initialization of cpuid entries
before passing them to the kernel.

At this chance also fix improper entry pointer progression and simplify
the code a bit.

This patch fixes a qcow2 corruption bug introduced in SVN Rev 5861. L2 tables
are big endian, so entries must be converted before being passed to functions.

This bug is easy to trigger. The following script will create and destroy a
qcow2 image (the header is gone after three loop iterations):

    #!/bin/bash
    qemu-img create -f qcow2 test.qcow 1M
    for i in $(seq 1 10); do
    qemu-system-x86_64 -hda test.qcow -monitor stdio > /dev/null 2>&1 <<EOF
    savevm test-$i
    quit
    EOF
    done

Create a new -smbios option (x86-only) to allow binary SMBIOS entries
to be passed through to the BIOS or modify the default values of
individual fields of type 0 and 1 entries on the command line.

Binary SMBIOS entries can be generated as follows:

dmidecode -t 1 -u | grep $'^\t\t[^"]' | xargs -n1 | \
        perl -lne 'printf "%c", hex($_)' > smbios_type_1.bin

These can then be passed to the BIOS using this switch:

 -smbios file=smbios_type_1.bin

Command line generation supports the following syntax:

 -smbios type=0[,vendor=str][,version=str][,date=str][,release=%d.%d]
 -smbios type=1[,manufacturer=str][,product=str][,version=str][,serial=str]
              [,uuid=$(uuidgen)][,sku=str][,family=str]

For instance, to add a serial number to the type 1 table:

 -smbios type=1,serial=0123456789

Interface is extensible to support more fields/tables as needed.

In theory, there are no more quirks in the KVM slot management that
requires dirty log start/stop all over the place. We just have to start
the logging each time the mapping may have changed. This patch drops
vga_dirty_log_stop for both standard and cirrus VGA. It also reverts
#6851 as it was obviously a tribute to the old slot system.

This reworks the slot management to handle more patterns of
cpu_register_physical_memory*, finally allowing to reset KVM guests (so
far address remapping on reset broke the slot management).

We could actually handle all possible ones without failing, but a KVM
kernel bug in older versions would force us to track all previous
fragmentations and maintain them (as that bug prevents registering
larger slots that overlap also deleted ones). To remain backward
compatible but avoid overly complicated workarounds, we apply a simpler
workaround that covers all currently used patterns.

Fail loudly if we run out of memory slot.

Make sure that dirty log start/stop works with consistent memory regions
by reporting invalid parameters. This reveals several inconsistencies in
the vga code, patch to fix them follows later in this series.

And, for simplicity reasons, also catch and report unaligned memory
regions passed to kvm_set_phys_mem (KVM works on page basis).

Testing for TLB_MMIO on unmap makes no sense as A) that flag belongs to
CPUTLBEntry and not to io_memory slots or physical addresses and B) we
already use a different condition before mapping. So make this test
consistent.

The patch called "prefer glibc over direct syscalls" (commit 7118) has
replaced the getcwd syscall with a call to the glibc. With this change,
the syscall is returning -1 in error case and 0 otherwise.
This is problematic as the sys_getcwd syscall should return the number
of bytes written to the buffer including the '\0'.
