2007-05-09md: allow reshape_position for md arrays to be set via sysfsNeilBrown
"reshape_position" records how much progress has been made on a "reshape" (adding drives, changing layout or chunksize). When it is set, the number of drives, layout and chunksize can have two possible values, an old an a new. So allow these different values to be visible, and allow both old and new to be set: Set the old ones first, then the reshape_position, then the new values.

2007-05-09Add suspend-related notifications for CPU hotplugRafael J. Wysocki
Since nonboot CPUs are now disabled after tasks and devices have been frozen and the CPU hotplug infrastructure is used for this purpose, we need special CPU hotplug notifications that will help the CPU-hotplug-aware subsystems distinguish normal CPU hotplug events from CPU hotplug events related to a system-wide suspend or resume operation in progress. This patch introduces such notifications and causes them to be used during suspend and resume transitions. It also changes all of the CPU-hotplug-aware subsystems to take these notifications into consideration (for now they are handled in the same way as the corresponding "normal" ones).

2007-05-08Documentation/i386/boot.txt: update and correctH. Peter Anvin
In the process of rewriting the x86 setup code, I found a number of inaccuracies and outdated recommendations in the boot protocol documentation. Revamp to make it more up to date. In particular, the common use of the heap actually requires (slightly) more than 4K of heap plus stack, which is the recommended amount in the document; currently the code compensates by being smaller than specified, but we can't assume that will be true forever. Thus, recommend that if we have a modern bzImage kernel, that the bootloader maximizes the available space. Signed-off-by: H.

2007-05-08x86, serial: convert legacy COM ports to platform devicesBjorn Helgaas
Make x86 COM ports into platform devices and don't probe for them if we have PNP. This prevents double discovery, where a device was found both by the legacy probe and by 8250_pnp, e.g., serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A 00:02: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A This also means IRDA devices without a UART PNP ID will no longer be claimed by the serial driver, which might require changes in IRDA drivers and administration. In addition to this patch, you may need to configure a setserial init script, e.g., /etc/init.d/setserial, so it doesn't poke legacy UART stuff back in. On Debian, "dpkg-reconfigure setserial" with the "kernel" option does this. To force the old legacy probe behavior even when we have PNPBIOS or ACPI, load the new legacy_serial module (or build 8250 static) with the "legacy_serial.force" option.

2007-05-08smsc-ircc2: add PNP supportBjorn Helgaas
Claim devices using PNP, unless the user explicitly specified device addresses. This can be disabled with the "smsc-ircc2.nopnp" option. This removes the need for probing legacy addresses and helps untangle IR devices from serial8250 devices. Sometimes the SMC device is at a legacy COM port address but does not use the legacy COM IRQ. In this case, claiming the device using PNP rather than 8250 legacy probe means we can automatically use the correct IRQ rather than forcing the user to use "setserial" to set the IRQ manually. If the PNP claim doesn't work, make sure you don't have a setserial init script, e.g., /etc/init.d/setserial, configured to poke in legacy COM port resources for the IRDA device. That causes the serial driver to claim resources needed by this driver.

A message will be printed out in such a case. o When a value 1 is echoed to the file, all probes (including ones registered in the intervening period) will be enabled o Unregistration will happen irrespective of whether probes are globally enabled or not. o Update Documentation/kprobes.txt to reflect these changes.

2007-05-08rtc: remove "RTC_ALM_SET mode" bugsDavid Brownell
This fixes a common glitch in how RTC drivers handle two "set alarm" modes, by getting rid of the surprising/hidden one that was rarely implemented correctly (and which could expose nonportable hardware-specific behavior). The glitch comes from the /dev/rtcX logic implementing the legacy RTC_ALM_SET (limited to 24 hours, needing RTC_AIE_ON) ioctl on top of the RTC driver call providing access to the newer RTC_WKALM_SET (without those limitations) by initializing the day/month/year fields to be invalid ... that second mode. Now, since few RTC drivers check those fields, and most hardware misbehaves when faced with invalid date fields, many RTC drivers will set bogus alarm times on those RTC_ALM_SET code paths. (Several in-tree drivers have that issue, and I also noticed it with code reviews on several new RTC drivers.) This patch ensures that RTC drivers never see such invalid alarm fields, by moving some logic out of rtc-omap into the RTC_ALM_SET code and adding an explicit check (which will prevent the issue on other code paths).

Add a filesystem API for <linux/spi/spi.h> stack. The initial version of this interface is purely synchronous. dbrownell@users.sourceforge.net: Cleaned up, bugfixed; much simplified; added preliminary documentation. Works with mdev given CONFIG_SYSFS_DEPRECATED; and presumably udev. Updated SPI_IOC_MESSAGE ioctl to full spi_message semantics, supporting groups of one or more transfers (each of which may be full duplex if desired). This is marked as EXPERIMENTAL with an explicit disclaimer that the API (notably the ioctls) is subject to change.

2007-05-08Fix chapter reference in CodingStyleJesper Juhl
commit 226a6b84aaaf1fac7a5d41cf4e7387fd9ba895d5 renumbered Chapter 11 in Documentation/CodingStyle to Chapter 12, but it didn't update the reference to that chapter further down in the file. This patch corrects the chapter reference.
