Pull x86 old platform removal from Peter Anvin: "This patchset removes support for several completely obsolete platforms, where the maintainers either have completely vanished or acked the removal. For some of them it is questionable if there even exists functional specimens of the hardware" Geert Uytterhoeven apparently thought this was a April Fool's pull request ;) * 'x86-nuke-platforms-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86, platforms: Remove NUMAQ x86, platforms: Remove SGI Visual Workstation x86, apic: Remove support for IBM Summit/EXA chipset x86, apic: Remove support for ia32-based Unisys ES7000

x86, vdso: Remove compat vdso support

2014-03-13T23:20:09Z

The compat vDSO is a complicated hack that's needed to maintain compatibility with a small range of glibc versions. This removes it and replaces it with a much simpler hack: a config option to disable the 32-bit vDSO by default. This also changes the default value of CONFIG_COMPAT_VDSO to n -- users configuring kernels from scratch almost certainly want that choice.

x86, platforms: Remove SGI Visual Workstation

2014-02-27T16:07:39Z

The SGI Visual Workstation seems to be dead; remove support so we don't have to continue maintaining it. Cc: Andrey Panin Cc: Michael Reed Link: http://lkml.kernel.org/r/530CFD6C.7040705@zytor.com Signed-off-by: H. Peter Anvin

ix86: Don't waste fixmap entries

2013-05-31T11:08:18Z

The vsyscall related pvclock entries can only ever be used on x86-64, and hence they shouldn't even get allocated for 32-bit kernels (the more that it is there where address space is relatively precious).

x86: Use a read-only IDT alias on all CPUs

2013-04-11T20:53:19Z

Make a copy of the IDT (as seen via the "sidt" instruction) read-only. This primarily removes the IDT from being a target for arbitrary memory write attacks, and has the added benefit of also not leaking the kernel base offset, if it has been relocated. We already did this on vendor == Intel and family == 5 because of the F0 0F bug -- regardless of if a particular CPU had the F0 0F bug or not. Since the workaround was so cheap, there simply was no reason to be very specific. This patch extends the readonly alias to all CPUs, but does not activate the #PF to #UD conversion code needed to deliver the proper exception in the F0 0F case except on Intel family 5 processors.
