The .discard/.discard.* sections are used to generate intermediate results for the assembler (effectively "test assembly".) The output is waste and should not be retained.

This patch add the time support for 32 bit a VDSO to a 32 bit kernel. For 32 bit programs running on a 32 bit kernel, the same mechanism is used as for 64 bit programs running on a 64 bit kernel.

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.

This revamps the vDSO linker script to lay things out with the best packing of the data and good, separate alignment of the code. The rigid layout using VDSO_TEXT_OFFSET no longer matters to the kernel. I've moved the layout parts of the linker script into a new include file, vdso-layout.lds.S; this is in preparation for sharing the script for the 32-bit vDSO builds too.
