Subject: [PATCH] util/udma_barrier.h: fix mips4 build
|
|
|
|
The 'sync' instruction for MIPS was defined in MIPS-II as taking no
|
|
operands. MIPS32 extended the define of 'sync' as taking an optional
|
|
unsigned 5 bit immediate.
|
|
|
|
As a result, replace "sync 0" by "sync" to fix the following build
|
|
failure on mips4 raised since version 43.0 and
|
|
https://github.com/linux-rdma/rdma-core/commit/b7c428344ea96d446f6ffe31c620a238a7f25c9e:
