doc: fix broken references

2011-09-27T16:08:04+00:00

There are numerous broken references to Documentation files (in other
Documentation files, in comments, etc.). These broken references are
caused by typo's in the references, and by renames or removals of the
Documentation files. Some broken references are simply odd.

Fix these broken references, sometimes by dropping the irrelevant text
they were part of.

KVM: Update documentation to include detailed ENABLE_CAP description

2011-09-25T16:52:31+00:00

We have an ioctl that enables capabilities individually, but no description
on what exactly happens when we enable a capability using this ioctl.

This patch adds documentation for capability enabling in a new section
of the API documentation.

KVM: x86: Raise the hard VCPU count limit

2011-09-25T16:17:57+00:00

The patch raises the hard limit of VCPU count to 254.

This will allow developers to easily work on scalability
and will allow users to test high VCPU setups easily without
patching the kernel.

To prevent possible issues with current setups, KVM_CAP_NR_VCPUS
now returns the recommended VCPU limit (which is still 64) - this
should be a safe value for everybody, while a new KVM_CAP_MAX_VCPUS
returns the hard limit which is now 254.

lguest: allow booting guest with CONFIG_RELOCATABLE=y

2011-08-15T00:45:10+00:00

The CONFIG_RELOCATABLE code tries to align the unpack destination to
the value of 'kernel_alignment' in the setup_hdr.  If that's 0, it
tries to unpack to address 0, which in fact causes the gunzip code
to call 'error("Out of memory while allocating output buffer")'.

The bootloader (ie. the lguest Launcher in this case) should be doing
setting this field; the normal bzImage is 16M, we can use the same.
