Adding asm-prototypes.h for genksyms to generate crc

2017-07-21T05:00:08Z

[ Upstream commit bdca8cc096203b17ad0ac4e19f50578207e054d2 ] This patch adds the prototypes of assembly defined functions to asm-prototypes.h. Some prototypes are directly added as they are not present in any existing header files. Signed-off-by: Nagarathnam Muthusamy Reviewed-by: Babu Moger Signed-off-by: David S.

sparc64: delete old wrap code

2017-06-14T13:07:36Z

[ Upstream commit 0197e41ce70511dc3b71f7fefa1a676e2b5cd60b ] The old method that is using xcall and softint to get new context id is deleted, as it is replaced by a method of using per_cpu_secondary_mm without xcall to perform the context wrap.

sparc64: add per-cpu mm of secondary contexts

[ Upstream commit 7a5b4bbf49fe86ce77488a70c5dccfe2d50d7a2d ] The new wrap is going to use information from this array to figure out mm's that currently have valid secondary contexts setup.

[ Upstream commit c4415235b2be0cc791572e8e7f7466ab8f73a2bf ] CTX_FIRST_VERSION defines the first context version, but also it defines first context. This patch redefines it to only include the first context version. Signed-off-by: Pavel Tatashin Reviewed-by: Bob Picco Reviewed-by: Steven Sistare Signed-off-by: David S.

sparc64: combine activate_mm and switch_mm

2017-06-14T13:07:36Z

[ Upstream commit 14d0334c6748ff2aedb3f2f7fdc51ee90a9b54e7 ] The only difference between these two functions is that in activate_mm we unconditionally flush context. However, there is no need to keep this difference after fixing a bug where cpumask was not reset on a wrap. So, in this patch we combine these.

sparc: Machine description indices can vary

[ Upstream commit c982aa9c304bf0b9a7522fd118fed4afa5a0263c ] VIO devices were being looked up by their index in the machine description node block, but this often varies over time as devices are added and removed. Instead, store the ID and look up using the type, config handle and ID. Signed-off-by: James Clarke Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=112541 Signed-off-by: David S.

sparc: Fix -Wstringop-overflow warning

2017-06-07T10:10:05Z

[ Upstream commit deba804c90642c8ed0f15ac1083663976d578f54 ] Greetings, GCC 7 introduced the -Wstringop-overflow flag to detect buffer overflows in calls to string handling functions [1][2]. Due to the way ``empty_zero_page'' is declared in arch/sparc/include/setup.h, this causes a warning to trigger at compile time in the function mem_init(), which is subsequently converted to an error. The ensuing patch fixes this issue and aligns the declaration of empty_zero_page to that of other architectures. Thank you. Cheers, Orlando.
