* sh: use set_current_blocked() and block_sigmask()Matt Fleming2012-03-292-49/+20
| | | | | | | | | | | | | | | | | | | | As described in e6fa16ab ("signal: sigprocmask() should do retarget_shared_pending()") the modification of current->blocked is incorrect as we need to check whether the signal we're about to block is pending in the shared queue. Also, use the new helper function introduced in commit 5e6292c0f28f ("signal: add block_sigmask() for adding sigmask to current->blocked") which centralises the code for updating current->blocked after successfully delivering a signal and reduces the amount of duplicate code across architectures. In the past some architectures got this code wrong, so using this helper function should stop that from happening again.

* sh: no need to reset handler if SA_ONESHOTMatt Fleming2012-03-292-6/+0
| | | | | | | | | | | | | | get_signal_to_deliver() already resets the signal handler if SA_ONESHOT is set in ka->sa.sa_flags, there's no need to do it again in handle_signal(). Furthermore, because we were modifying ka->sa.sa_handler (which is a copy of sighand->action[]) instead of sighand->action[] the original code had no effect on signal delivery.

* sh: intc: Fix up section mismatch for intc_ack_dataPaul Mundt2012-03-291-3/+2
| | | | | | | | | | | | | | | | intc_ack_data is flagged as __init when it shouldn't be, causing section mismatches in non-init paths like intc_set_ack_handle(): WARNING: drivers/built-in.o(.text+0x5d760): Section mismatch in reference from the function intc_set_ack_handle() to the function .init.text:intc_ack_data() The function intc_set_ack_handle() references the function __init intc_ack_data(). This is often because intc_set_ack_handle lacks a __init annotation or the annotation of intc_ack_data is wrong.

* sh: Avoid exporting unimplemented syscalls.Paul Mundt2012-03-284-70/+71
| | | | | | | | | | | | | | | | Now that userspace is making use of kernel-provided sanitized headers for working out supported interfaces, we need to be a bit more diligent with matching the syscall definitions with their actual wiring/support state. In theory it shouldn't hurt anything since sys_ni_syscall will ultimately do the right thing, but there's also not much need to lie about legacy x86 syscalls that we've never supported. This tightens things up a bit for uClibc at least. Suggested-by: Carmelo Amoroso <carmelo.amoroso@st.com> Acked-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* serial: sh-sci: fix a race of DMA submit_tx on transferYoshii Takashi2012-03-281-5/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When DMA is enabled, sh-sci transfer begins with uart_start() sci_start_tx() if (cookie_tx < 0) schedule_work() Then, starts DMA when wq scheduled, -- (A) process_one_work() work_fn_rx() cookie_tx = desc->submit_tx() And finishes when DMA transfer ends, -- (B) sci_dma_tx_complete() async_tx_ack() cookie_tx = -EINVAL (possible another schedule_work()) This A to B sequence is not reentrant, since controlling variables (for example, cookie_tx above) are not queues nor lists. So, they must be invoked as A B A B..., otherwise results in kernel crash. To ensure the sequence, sci_start_tx() seems to test if cookie_tx < 0 (represents "not used") to call schedule_work(). But cookie_tx will not be set (to a cookie, also means "used") until in the middle of work queue scheduled function work_fn_tx(). This gap between the test and set allows the breakage of the sequence under the very frequently call of uart_start(). Another gap between async_tx_ack() and another schedule_work() results in the same issue, too. This patch introduces a new condition "cookie_tx == 0" just to mark it is "busy" and assign it within spin-locked region to fill the gaps.
