Subject: [PATCH] ec: Use static linkage on nistp521 felem_{square,mul}
|
||||
wrappers
|
||||
|
||||
Runtime selection of implementations for felem_{square,mul} depends on
|
||||
felem_{square,mul}_wrapper functions, which overwrite function points in
|
||||
a similar design to that of .plt.got sections used by program loaders
|
||||
during dynamic linking.
|
||||
|
||||
There's no reason why these functions need to have external linkage.
|
||||
Mark static.

Subject: [PATCH] powerpc: ecc: Fix stack allocation secp384r1 asm
|
||||
|
||||
Assembly acceleration secp384r1 opts to not use any callee-save VSRs, as
|
||||
VSX enabled systems make extensive use of renaming, and so writebacks in
|
||||
felem_{mul,square}() can be reordered for best cache effects.
|
||||
|
||||
Remove stack allocations. This in turn fixes unmatched push/pops in
|
||||
felem_{mul,square}().
