2016-03-11staging: rtl8192e: rtl8192e: Remove create_workqueue()Amitoj Kaur Chawla
With conccurency managed workqueues, use of dedicated workqueues can be replaced by system_wq. Drop priv_wq by using system_wq. Since there are multiple work items per priv but they do not need to be ordered, increase of concurrency by switching to system_wq should not break anything. All work items are sync canceled on so it is guaranteed that no work is running when rtl92e_suspend function is called.

2016-03-11staging: rtl8192e: Prefer using macro DIV_ROUND_UPBhaktipriya Shridhar
The macro DIV_ROUND_UP performs the computation (((n) + (d) - 1) /(d)). It clarifies the divisor calculations. This was done using the coccinelle script: @@ expression e1; expression e2; @@ ( - ((e1) + e2 - 1) / (e2) + DIV_ROUND_UP(e1,e2) | - ((e1) + (e2 - 1)) / (e2) + DIV_ROUND_UP(e1,e2) ) Signed-off-by: Bhaktipriya Shridhar <bhaktipriya96@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

With conccurency managed workqueues, use of dedicated workqueues can be replaced by system_wq. Drop wq by using system_wq. Since there are multiple work items per rtllib but they do not need to be ordered, increase of concurrency by switching to system_wq should not break anything.

2016-03-12ARC: [BE] readl()/writel() to work in Big Endian CPU configurationLada Trimasova
read{l,w}() write{l,w}() primitives should use le{16,32}_to_cpu() and cpu_to_le{16,32}() respectively to ensure device registers are read correctly in Big Endian CPU configuration. Per Arnd Bergmann | Most drivers using readl() or readl_relaxed() expect those to perform byte | swaps on big-endian architectures, as the registers tend to be fixed endian This was needed for getting UART to work correctly on a Big Endian ARC.
