Host patches (SKAS & SYSEMU)

To compile a 2.6 host kernel with the SKAS patch

Take a 2.6 kernel, without any patch applied (i.e. a "vanilla" kernel).
Apply the appropriate SKAS patch for your kernel version.
Now configure the kernel (without ARCH=um, this is a host kernel), enable /proc/mm under "Processor type and features" menu if needed, save the new configuration and build it:
```
      make menuconfig/make xconfig
      make
      make modules_install
    
```
Install the new kernel in your bootloader.

2.4 skas patch

Use it like the normal skas3 patch, basically. Note that you do not any more need to activate '/proc/mm': if you want to disable it, unapply the patch, since without that option on the patch has never been working (and I did not fix this), but you must do a make oldconfig/menuconfig/xconfig and save the new configuration, or the .config will not be updated and the build will fail.

2.4 guest patches - how to apply them.

Before applying these ones, instead, you must download and apply uml-patch-2.4.24-1base.patch.bz2, on a 2.4.27 (or probably even a later one) kernel, and then apply on top of it the latest -bs release, which currently is 2.4.27-1bs. To build one UML kernel with these patches applied, you must follow the general UML compiling instructions you find on the main UML site (see the Links page if you don't know it).

How to apply them

To compile a UML 2.6 guest kernel

Choose which version of the UML patch to use. You can find the official patches on the main UML site; you can find here, in the patch list of this site, my UML updates.
In the site FAQs, you can find an entry about choosing the better version to use.
Download the 2.6 kernel matching the UML patch you want to use; it must be a "vanilla" kernel, i.e. without any patch applied.
Download the UML patch.
Go to the root of the kernel tree and apply the base Uml patch:
```
      bzcat uml-patch-version.bz2|patch -p1
    
```
Configure the kernel for UML: remember to enable /proc/mm under UML-specific options, and avoid enabling SMP support: if you are lucky, it will have no difference from an UniProcessor kernel; you can only get more problems.
```
      make menuconfig ARCH=um
    
```
Build it and enjoy:
```
      make linux modules ARCH=um
    
```
see also compiling instructions on UML main site.

How to apply both the Uml patch and the SKAS patch on the same kernel tree

The SKAS patch and the UML patch cannot be applied on the same kernel tree. And this will not change, since it's better anyway to have separate trees for them.
