Linux 2.2.18 Release Notes
Platforms:Alpha, M68K, PowerPC, S/390, Sparc, X86
Introduction Linux 2.2.18 is the latest update to the Linux kernel tree. The out of the box tree supports the Alpha, PPC, Sparc and X86 platforms. MIPS and ARM are mostly merged but you should obtain the platform specific tree.
Compilers This code is intended to build with gcc 2.7.2 and egcs 1.1.2. Patches for building with gcc 2.95 are merged but less tested than other compilers. Caution is recommended when using gcc 2.95 and feedback is sought.
Binary Compatibility Linux 2.2.18 should on the whole be fully binary compatible with old modules. There are no API changes, although 2.4 back compatibility API's are also introduced in this release. In general you should not assume binary compatibility between kernel object modules in Linux.
Security Notes
Linux 2.2.18 contains additional 2.4test ABI calls for controlling how capabilities are handled when using setuid calls.
Architecture Updates
Alpha
+ Fixed a problem where csum_partial_copy could cause spurious EFAULT returns + Fixed a problem with FPU division
ARM The ARM tree has been partially synchronized with the ARM working tree for 2.2
i386 The major thrust has been support for processors running in excess of 2GHz, support for the CyrixIII processor and also basic support for the Pentium IV. Unfortunately Intel chose to ignore all precedent in model numbering via cpuid and report a family of '15'. This sudden jump broke assumptions in the kernel tree without any warning. Intel have failed to provide good reasons for their change. We have chosen to continue to report the Pentium IV as a '686' class processor. The full family data is provided via cpuinfo.
In addition the early Pentium IV chips appear to have some problems. You should be using stepping 7 or higher processors with the latest shipping microcode update if you wish to run Linux on a Pentium IV processor.
+ Added a DMI scanner to handle broken Dell laptop APM + Added microcode update support from the 2.4test tree + Added msr/cpuid driver backport from 2.4test + Added support for processors running at over 2GHz + Experimental Cyrix III support + Fixed slight abuse of gcc inline asm in maths emulator + Fixed some minor bugs in the CPU failure reporting + Fixed db6 handling when doing ptrace + Intel Pentium IV support + Support both keyboard and 'fast' A20 gating + Updated MTRR support to handle the K6 mobile
M68K Merge with the forked off M68K stable kernel tree
PowerPC Merge with the PPC maintainers. Fix a problem with the syscall table
S/390 The S/390 tree has been brought back into sync with IBM
Sparc
+ Updates for DRM and other ioctl changes + Fix dcache and exec problems
