* rtc-cmos alarm acts as oneshotDavid Brownell2008-02-06
| | | | | | | | | | | | | | | | | | | | | Start making the rtc-cmos alarm act more like a oneshot alarm by disabling that alarm after its IRQ fires. (ACPI hooks are also needed.) The Linux RTC framework has previously been a bit vague in this area, but any other behavior is problematic and not very portable. RTCs with full YYYY-MM-DD HH:MM[:SS] alarms won't have a problem here. Only ones with partial match criteria, with the most visible example being the PC RTC, get confused. (Because the criteria will match repeatedly.) Update comments relating to that oneshot behavior and timezone handling. (Timezones are another issue that's mostly visible with rtc-cmos. That's because PCs often dual-boot MS-Windows, which likes its RTC to match local wall-clock time instead of UTC.)

* rtc: ds1302 rtc supportPaul Mundt2008-02-06
| | | | | | | | | | | | | | | | | This adds a basic ds1302 RTC driver, which is basically a cleanup and move of the in-tree SH SecureEdge5410 code (which is currently located in arch/sh/board/snapgear/rtc.c) to drivers/rtc. This aims to be a building block that the M32R and CRIS code can be worked on top of, so we can get rid of drivers/char/ds1302.c and arch/cris/arch-v10/drivers/ds1302.c respectively, though more work is needed for this.

* rtc-cmos: export nvram in sysfsDavid Brownell2008-02-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | This makes rtc-cmos export its NVRAM, like several other RTC drivers. It still works within the limits of the current CMOS_READ/CMOS_WRITE calls, which don't understand how to access multiple register banks. The primary impact of that limitation is that Linux can't access the uppermost 128 bytes of NVRAM on many systems. Note that this isn't aiming to be a drop-in replacement for the legacy /dev/nvram support. (Presumably that has real users, and isn't just getting carried forward automatically?) Userspace handles more work: - When userspace code updates NVRAM, that will need to include updating any platform-specific checksums that may apply. - No /proc/driver/nvram file will parse and display NVRAM data according to whichever boot firmware your board expects. Also minor pnp-related updates: update a comment, remove dead code.

* atmel_spi: fix dmachain oops with DEBUG enabledHaavard Skinnemoen2008-02-06
| | | | | | | | | | | | | | | | In atmel_spi_next_xfer, xfer can be NULL because the next transfer may already have been submitted to the PDC (using DMA chaining). This can cause an oops, since the debug message assumed it was never null. The fix changes how those debug messages are issued, ensuring that one is issued each time a transfer is started instead of once per call. Also, properly indent the "can this transfer be chained" test so it's not hidden as if it were non-conditional code.

| | | | | | | | | | | | | | | | | | | | | | | | | | Add support for chained transfers in the atmel_spi driver, letting the DMA controller switch to the next buffer pair without CPU intervention. This reduced I/O latencies by about 2% in one bulk I/O test. It should also help work around several interrelated errata affecting chipselect 0 on at91rm9200 chips. Almost all of the changes are in the reworked atmel_spi_next_xfer() function. That's now called with the driver in one of three states: 1. It isn't transferring anything (in which case the first transfer of the current message is going to be sent) 2. It has finished transfering a non-chainable transfer (in which case it will go to the next transfer in the message) 3. It has finished transfering a chained transfer (in which case the next transfer is already queued) After that it will queue the next transfer if it can be chained.

* Claim maintainership for block2mtd and update email addressesJoern Engel2008-02-06
| | | | | | | | | | | | | | I have been prime author and maintainer of block2mtd from day one, but neither MAINTAINERS nor the module source makes this fact clear. And while I'm at it, update my email addresses tree-wide, as the old address currently bounces and change my name to "joern" as unicode will likely continue to cause trouble until the end of this century.

* Fix IXANY and restart after signal (e.g. ctrl-C) in n_tty line disciplineJoe Peterson2008-02-06
| | | | | | | | | | | | | | | | | | | | | | | | Fix two N_TTY line discipline issues related to resuming a stopped TTY (typically done with ctrl-S): 1) Fix handling of character that resumes a stopped TTY (with IXANY) With "stty ixany", the TTY line discipline would lose the first character after the stop, so typing, for example, "hi^Sthere" resulted in "hihere" (the 't' would cause the resume after ^S, but it would then be thrown away rather than processed as an input character). This was inconsistent with the behavior of other Unix systems. 2) Fix interrupt signal (e.g. ctrl-C) behavior in stopped TTYs With "stty -ixany" (often the default), interrupt signals were ignored in a stopped TTY until the TTY was resumed with the start char (typically ctrl-Q), which was inconsistent with the behavior of other Unix systems.

* calibrate_delay() must be __cpuinitAdrian Bunk2008-02-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | calibrate_delay() must be __cpuinit, not __{dev,}init. I've verified that this is correct for all users. While doing the latter, I also did the following cleanups: - remove pointless additional prototypes in C files - ensure all users #include <linux/delay.h> This fixes the following section mismatches with CONFIG_HOTPLUG=n, CONFIG_HOTPLUG_CPU=y: WARNING: vmlinux.o(.text+0x1128d): Section mismatch: reference to .init.text.1:calibrate_delay (between 'check_cx686_slop' and 'set_cx86_reorder') WARNING: vmlinux.o(.text+0x25102): Section mismatch: reference to .init.text.1:calibrate_delay (between 'smp_callin' and 'cpu_coregroup_map') Signed-off-by: Adrian Bunk <bunk@kernel.org> Cc: Ivan Kokshaysky <ink@jurassic.park.msu.ru> Cc: Richard Henderson <rth@twiddle.net> Cc: "Luck, Tony" <tony.luck@intel.com> Cc: Ralf Baechle <ralf@linux-mips.org> Cc: Paul Mackerras <paulus@samba.org> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: "David S.
