parisc: Fix access fault handling in pa_memcpy()

2017-03-29T19:49:02Z

pa_memcpy() is the major memcpy implementation in the parisc kernel which is used to do any kind of userspace/kernel memory copies. Al Viro noticed various bugs in the implementation of pa_mempcy(), most notably that in case of faults it may report back to have copied more bytes than it actually did. Fixing those bugs is quite hard in the C-implementation, because the compiler is messing around with the registers and we are not guaranteed that specific variables are always in the same processor registers. This makes proper fault handling complicated. This patch implements pa_memcpy() in assembler. That way we have correct fault handling and adding a 64-bit copy routine was quite easy. Runtime tested with 32- and 64bit kernels. Reported-by: Al Viro Cc: # v4.9+ Signed-off-by: John David Anglin Signed-off-by: Helge Deller

parisc: do not inline pa_memcpy() internal functions

2013-11-19T22:36:16Z

gcc (4.8.x) creates wrong code when the pa_memcpy() functions are inlined. Especially in 32bit builds it calculates wrong return values if we encounter a fault during execution of the memcpy. Signed-off-by: Helge Deller
