sh64: failing __get_user() should zero

2016-09-13T21:50:14+00:00

It could be done in exception-handling bits in __get_user_b() et.al., but the surgery involved would take more knowledge of sh64 details than I have or _want_ to have. Cc: stable@vger.kernel.org Signed-off-by: Al Viro

sh: fix put_user sparse errors

2015-01-13T13:23:38+00:00

virtio wants to write bitwise types to userspace using put_user. At the moment this triggers sparse errors, since the value is passed through an integer. For example: __le32 __user *p; __le32 x; put_user(x, p); is safe, but currently triggers a sparse warning. Fix that up using __force. Note: this does not suppress any useful sparse checks since caller assigns x to typeof(*p), which in turn forces all the necessary type checks. Signed-off-by: Michael S. Tsirkin

sh: use the new generic strnlen_user() function

2012-06-13T01:28:37+00:00

This discards both the _32 and _64 versions in favour of the consolidated generic one. Signed-off-by: Paul Mundt

sh: switch to generic strncpy_from_user().

2012-06-13T01:28:16+00:00

This kills off the special sh32/64 versions and adopts the generic version. It should be possible to optimize this for SH-4A unaligned loads, but this is a corner case that can be supported incrementally. Signed-off-by: Paul Mundt

sh64: re-add the __strnlen_user() prototype

2008-08-25T05:07:58+00:00

Commit 42fd3b142d8867f5b58d6fb75592cd20fd654c1b (sh: Initial consolidation of the _32/_64 uaccess split.) mistakenly removed the sh64 __strnlen_user() prototype, resulting in the following compile error: <-- snip --> ...
