arm: Remove 32bit KVM host support

That's it. Remove all references to KVM itself, and document
that although it is no more, the ABI between SVC and HYP still
exists.

@@ -11,6 +11,11 @@ hypervisor when running as a guest (under Xen, KVM or any other
 hypervisor), or any hypervisor-specific interaction when the kernel is
 used as a host.
 
+Note: KVM/arm has been removed from the kernel. The API described
+here is still valid though, as it allows the kernel to kexec when
+booted at HYP. It can also be used by a hypervisor other than KVM
+if necessary.
+
 On arm and arm64 (without VHE), the kernel doesn't run in hypervisor
 mode, but still needs to interact with it, allowing a built-in
 hypervisor to be either installed or torn down.

-/********************************************************************
- * Hypervisor exception vector and handlers
- *
- *
- * The KVM/ARM Hypervisor ABI is defined as follows:
- *
- * Entry to Hyp mode from the host kernel will happen _only_ when an HVC
- * instruction is issued since all traps are disabled when running the host
- * kernel as per the Hyp-mode initialization at boot time.
- *
- * HVC instructions cause a trap to the vector page + offset 0x14 (see hyp_hvc
- * below) when the HVC instruction is called from SVC mode (i.e. a guest or the
- * host kernel) and they cause a trap to the vector page + offset 0x8 when HVC
- * instructions are called from within Hyp-mode.
- *
- * Hyp-ABI: Calling HYP-mode functions from host (in SVC mode):
- *    Switching to Hyp mode is done through a simple HVC #0 instruction. The
- *    exception vector code will check that the HVC comes from VMID==0.
- *    - r0 contains a pointer to a HYP function
- *    - r1, r2, and r3 contain arguments to the above function.
- *    - The HYP function will be called with its arguments in r0, r1 and r2.
- *    On HYP function return, we return directly to SVC.
- *
- * Note that the above is used to execute code in Hyp-mode from a host-kernel
- * point of view, and is a different concept from performing a world-switch and
- * executing guest code SVC mode (with a VMID != 0).
