[PATCH v3 12/24] lib: vdso: Add compat support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Some 64 bit architectures have support for 32 bit applications that
require a separate version of the vDSOs.

This patch adds support to the generic code for compat fallback
functions.
