Subject: x32: Drop non-__vdso weak symbols from the x32 VDSO
X-Git-Tag: v3.4-rc1~33^2~12
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=862ae3132dc393ab6ea750b9ee9e0e1c276b9abb;p=platform%2Fupstream%2Fkernel-adaptation-pc.git

x32: Drop non-__vdso weak symbols from the x32 VDSO

Drop the legacy weak symbols that don't carry the __vdso prefix from
the x32 VDSO.  This is a new ABI and we don't need to support that
legacy; the actual libc will export the proper symbols.
