Revert "net/sunrpc: Use static const char arrays"
This reverts commit 411b5e05617593efebc06241dbc56f42150f2abe.
Olga Kornievskaia reports:
Problem: linux client mounting linux server using rc4-hmac-md5
enctype. gssd fails with create a context after receiving a reply from
the server.
Diagnose: putting printout statements in the server kernel and
kerberos libraries revealed that client and server derived different
integrity keys.
Server kernel code was at fault due the the commit
[aglo@skydive linux-pnfs]$ git show 411b5e05617593efebc06241dbc56f42150f2abe
Trond: The problem is that since it relies on virt_to_page(), you cannot
call sg_set_buf() for data in the const section.
