* pch_uart: Fix dma channel unallocated issueTomoya MORINAGA2012-04-181-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | This driver anticipates pch_uart_verify_port() is not called during installation. However, actually pch_uart_verify_port() is called during installation. As a result, memory access violation occurs like below. 0. initial value: use_dma=0 1. starup() - dma channel is not allocated because use_dma=0 2. pch_uart_verify_port() - Set use_dma=1 3. UART processing acts DMA mode because use_dma=1 - memory access violation occurs! This patch fixes the issue. Solution: Whenever pch_uart_verify_port() is called and then dma channel is not allocated, the channel should be allocated.

| * pch_uart: Add Kontron COMe-mTT10 uart clock quirkMichael Brunner2012-04-091-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add UART clock quirk for the Kontron COMe-mTT10 module. The board has previously been called nanoETXexpress-TT, therefore this is also checked. As suggested by Darren Hart the comparison in this patch version is placed after the FRI2 checks to ensure it will also work with possible upcoming changes to the FRI2 firmware. This patch follows the patchset submitted by Darren Hart at commit a46f5533ecfc7bbdd646d84fdab8656031a715c6.

| * serial/8250_pci: add a "force background timer" flag and use it for the "kt" ↵Dan Williams2012-04-092-4/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | serial port Workaround dropped notifications in the iir register. Register reads coincident with new interrupt notifications sometimes result in this device clearing the interrupt event without reporting it in the read data. The serial core already has a heuristic for determining when a device has an untrustworthy iir register. In this case when we apriori know that the iir is faulty use a flag (UPF_BUG_THRE) to bypass the test and force usage of the background timer.

| * Revert "serial/8250_pci: setup-quirk workaround for the kt serial controller"Dan Williams2012-04-092-19/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 448ac154c957c4580531fa0c8f2045816fe2f0e7. The semantic of UPF_IIR_ONCE is only guaranteed to workaround the race condition in the kt serial's iir register if the only source of interrupts is THRE (fifo-empty) events. An modem status event at the wrong time can again cause an iir read to drop the 'empty' status leading to a hang. So, revert this in preparation for using the existing "I don't trust my iir register" workaround in the 8250 core (UART_BUG_THRE).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit e86ff4a63c9fdd875ba8492577cd1ad2252f525c. This tried to enforce the semantics of one interrupt per iir read of the THRE (transmit-hold empty) status, but events from other sources (particularly modem status) defeat this guarantee. This change also broke 8250_pci suspend/resume support as pciserial_resume_ports() re-runs .init() quirks, but does not run .exit() quirks in pciserial_suspend_ports() leading to reports like: sysfs: cannot create duplicate filename '/devices/pci0000:00/0000:00:16.3/msi_irqs' ...and a subsequent crash. The mismatch of init/exit at suspend/resume seems like a bug in its own right.

| * tty/serial: atmel_serial: fix RS485 half-duplex problemSiftar, Gabe2012-04-091-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On our custom board, we are using RS485 in half-duplex mode on an AT91SAM9G45. SER_RS485_RX_DURING_TX is not set as we do not want to receive the data we transmit (our transceiver will receive transmitted data). Although the current driver attempts to disable and enable the receiver at the appropriate points, incoming data is still loaded into the receive register causing our code to receive the very last byte that was sent once the receiver is enabled. I ran this by Atmel support and they wrote: "The issue comes from the fact that you disable the PDC/DMA Reception and not the USART Reception channel. In your case, the[n] you will still receive data into the USART_RHR register, and maybe you [h]ave the overrun flag set. So please disable the USART reception channel." The following patch should force the driver to enable/disable the receiver via RXEN/RXDIS fields of the USART control register. It fixed the issue I was having.

With the recent changes we do not need force_ to kill the CLONE_NEWPID tasks. And this is more correct. force_sig() can race with the exiting thread, while do_send_sig_info(group => true) kill the whole process. Some more notes from Oleg Nesterov: > Just one note. This change makes no difference for sysrq_handle_kill(). > But it obviously changes the behaviour sysrq_handle_term(). I think > this is fine, if you want to really kill the task which blocks/ignores > SIGTERM you can use sysrq_handle_kill(). > > Even ignoring the reasons why force_sig() is simply wrong here, > force_sig(SIGTERM) looks strange.

Also, > force_sig() can't kill the process if the main thread has already > exited. IOW, it is trivial to create the process which can't be > killed by sysrq. So, this patch fixes the issue.

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.

I've built all the working defconfigs from all the arches that I can and made sure that they don't break. The reason for these patches is that I recently encountered a circular dependency problem that came about when I produced some patches to optimise get_order() by rewriting it to use ilog2(). This uses bitops - and on the SH arch asm/bitops.h drags in asm-generic/get_order.h by a circuituous route involving asm/system.h. The main difficulty seems to be asm/system.h. It holds a number of low level bits with no/few dependencies that are commonly used (eg. memory barriers) and a number of bits with more dependencies that aren't used in many places (eg. switch_to()). These patches break asm/system.h up into the following core pieces: (1) asm/barrier.h Move memory barriers here. This already done for MIPS and Alpha. (2) asm/switch_to.h Move switch_to() and related stuff here. (3) asm/exec.h Move arch_align_stack() here. Other process execution related bits could perhaps go here from asm/processor.h. (4) asm/cmpxchg.h Move xchg() and cmpxchg() here as they're full word atomic ops and frequently used by atomic_xchg() and atomic_cmpxchg(). (5) asm/bug.h Move die() and related bits. (6) asm/auxvec.h Move AT_VECTOR_SIZE_ARCH here. Other arch headers are created as needed on a per-arch basis." Fixed up some conflicts from other header file cleanups and moving code around that has happened in the meantime, so David's testing is somewhat weakened by that. We'll find out anything that got broken and fix it.. * tag 'split-asm_system_h-for-linus-20120328' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-asm_system: (38 commits) Delete all instances of asm/system.h Remove all #inclusions of asm/system.h Add #includes needed to permit the removal of asm/system.h Move all declarations of free_initmem() to linux/mm.h Disintegrate asm/system.h for OpenRISC Split arch_align_stack() out from asm-generic/system.h Split the switch_to() wrapper out of asm-generic/system.h Move the asm-generic/system.h xchg() implementation to asm-generic/cmpxchg.h Create asm-generic/barrier.h Make asm-generic/cmpxchg.h #include asm-generic/cmpxchg-local.h Disintegrate asm/system.h for Xtensa Disintegrate asm/system.h for Unicore32 [based on ver #3, changed by gxt] Disintegrate asm/system.h for Tile Disintegrate asm/system.h for Sparc Disintegrate asm/system.h for SH Disintegrate asm/system.h for Score Disintegrate asm/system.h for S390 Disintegrate asm/system.h for PowerPC Disintegrate asm/system.h for PA-RISC Disintegrate asm/system.h for MN10300 ...

According to Haojian Zhuang, removing the sa1100 rtc dummy clock is the correct fix here. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
