2007-02-12[PATCH] Minix V3 supportAndries Brouwer
This morning I needed to read a Minix V3 filesystem, but unfortunately my 2.6.19 did not support that, and neither did the downloaded 2.6.20rc4. Fortunately, google told me that Daniel Aragones had already done the work, patch found at http://www.terra.es/personal2/danarag/ Unfortunaly, looking at the patch was painful to my eyes, so I polished it a bit before applying. The resulting kernel boots, and reads the filesystem it needed to read.

2007-02-12[PATCH] SPI eeprom driverDavid Brownell
This is adds a simple SPI EEPROM driver, providing access to the EEPROM through sysfs much like the I2C "eeprom" driver ... except this driver supports write access, and multiple EEPROM sizes. From: "Tuppa, Walter" <walter.tuppa@siemens.com> Since I have EEPROMs on SPI with different address sizing, I made some changes to your at25.c to support them. Works perfectly. (Also includes a small bugfix for the "what size address" test.)

2007-02-12[PATCH] SPI doc clarificationsDavid Brownell
This clarifies some aspects of the SPI programming interface, based on feedback from Hans-Peter Nilsson. The in-memory representation of words is right-aligned, so for example a twelve bit word is stored using sixteen bits with four undefined bits in the MSB. And controller drivers must reject protocol tweaking modes they do not support.

2007-02-12[PATCH] SPI cleanup() method param becomes non-constHans-Peter Nilsson
I'd like to assign NULL to kfree()d members of a structure. I can't do that without ugly casting (see the PXA patch) when the structure pointed to is const-qualified. I don't really see a reason why the cleanup method isn't allowed to alter the object it should clean up. :-) No, I didn't test the PXA patch, but I verified that the NULL-assignment doesn't stop me from doing rmmod/insmodding my own spi_bitbang-based driver.

2007-02-12[PATCH] SPI: Freescale iMX SPI controller driver (BIS+)Andrea Paterniani
Add the SPI controller driver for Freescale i.MX(S/L/1). Main features summary: > Per chip setup via board specific code and/or protocol driver. > Per transfer setup. > PIO transfers. > DMA transfers. > Managing of NULL tx / rx buffer for rd only / wr only transfers. This patch replace patch-2.6.20-rc4-spi_imx with the following changes: > Few cosmetic changes. > Function map_dma_buffers now return 0 for success and -1 for failure. > Solved a bug inside spi_imx_probe function (wrong error path). > Solved a bug inside setup function (bad undo setup for max_speed_hz). > For read-only transfers, always write zero bytes. This is almost the same as the 'BIS' version sent by Andrea, except for updating the 'DUMMY' byte so that read-only transfers shift out zeroes. That part of the API changed recently, since some half duplex peripheral chips require that semantic.

2007-02-12[PATCH] Make BH_Unwritten a first class bufferhead flag V2David Chinner
Currently, XFS uses BH_PrivateStart for flagging unwritten extent state in a bufferhead. Recently, I found the long standing mmap/unwritten extent conversion bug, and it was to do with partial page invalidation not clearing the unwritten flag from bufferheads attached to the page but beyond EOF. See here for a full explaination: http://oss.sgi.com/archives/xfs/2006-12/msg00196.html The solution I have checked into the XFS dev tree involves duplicating code from block_invalidatepage to clear the unwritten flag from the bufferhead(s), and then calling block_invalidatepage() to do the rest. Christoph suggested that this would be better solved by pushing the unwritten flag into the common buffer head flags and just adding the call to discard_buffer(): http://oss.sgi.com/archives/xfs/2006-12/msg00239.html The following patch makes BH_Unwritten a first class citizen.

So we'll just need to replace NO_IOPORT with NO_IOMEM in Kconfig and kill arch/s390/mm/ioremap.c. BTW, there's an annoying bit of junk in there - IO_SPACE_LIMIT. We only need it for /proc/ioports, which AFAICS shouldn't even be there on s390 (or uml).

2007-02-11[PATCH] rapidio: fix multi-switch enumerationAlexandre Bounine
This patch contains two fixes for RapisIO enumeration logic: 1. Fix enumeration in configurations with multiple switches. The patch adds: a. Enumeration of an empty switch. Empty switch is a switch that does not have any endpoint devices attached to it (except host device or previous switch in a chain). New code assigns a phony destination ID associated with the switch and sets up corresponding routes. b. Adds a second pass to the enumeration to setup routes to devices discovered after switch was scanned. 2. Fix enumeration failure when riohdid parameter has non-zero value. Current version fails to setup response path to the host when it has destination ID other that 0.

2007-02-11[PATCH] extend the set of "__attribute__" shortcut macrosRobert P. J. Day
Extend the set of "__attribute__" shortcut macros, and remove identical (and now superfluous) definitions from a couple of source files. based on a page at robert love's blog: http://rlove.org/log/2005102601 extend the set of shortcut macros defined in compiler-gcc.h with the following: #define __packed __attribute__((packed)) #define __weak __attribute__((weak)) #define __naked __attribute__((naked)) #define __noreturn __attribute__((noreturn)) #define __pure __attribute__((pure)) #define __aligned(x) __attribute__((aligned(x))) #define __printf(a,b) __attribute__((format(printf,a,b))) Once these are in place, it's up to subsystem maintainers to decide if they want to take advantage of them. there is already a strong precedent for using shortcuts like this in the source tree. The ones that might give people pause are "__aligned" and "__printf", but shortcuts for both of those are already in use, and in some ways very confusingly. note the two very different definitions for a macro named "ALIGNED": drivers/net/sgiseeq.c:#define ALIGNED(x) ((((unsigned long)(x)) + 0xf) & ~(0xf)) drivers/scsi/ultrastor.c:#define ALIGNED(x) __attribute__((aligned(x))) also: include/acpi/platform/acgcc.h: #define ACPI_PRINTF_LIKE(c) __attribute__ ((__format__ (__printf__, c, c+1))) Given the precedent, then, it seems logical to at least standardize on a consistent set of these macros.

2007-02-11[PATCH] RTC framework driver for CMOS RTCsDavid Brownell
This is an "RTC framework" driver for the "CMOS" RTCs which are standard on PCs and some other platforms. That's MC146818 compatible silicon. Advantages of this vs. drivers/char/rtc.c (use one _or_ the other, only one will be able to claim the RTC irq) include: - This leverages both the new RTC framework and the driver model; both PNPACPI and platform device modes are supported. (A separate patch creates a platform device on PCs where PNPACPI isn't configured.) - It supports common extensions like longer alarms. (A separate patch exports that information from ACPI through platform_data.) - Likewise, system wakeup events use "real driver model support", with policy control via sysfs "wakeup" attributes and and using normal rtc ioctls to manage wakeup. (Patch in the works. The ACPI hooks are known; /proc/acpi/alarm can vanish. Making it work with EFI will be a minor challenge to someone with e.g. a MiniMac.) It's not yet been tested on non-x86 systems, without ACPI, or with HPET. And the RTC framework will surely have teething pains on "mainstream" PC-based systems (though must embedded Linux systems use it heavily), not limited to sorting out the "/dev/rtc0" issue (udev easily tweaked). Also, the ALSA rtctimer code doesn't use the new RTC API. Otherwise, this should be a no-known-regressions replacement for the old drivers/char/rtc.c driver, and should help the non-embedded distros (and the new timekeeping code) start to switch to the framework. Note also that any systems using "rtc-m48t86" are candidates to switch over to this more functional driver; the platform data is different, and the way bytes are read is different, but otherwise those chips should be compatible.

2007-02-11[PATCH] Common compat_sys_sysinfoKyle McMartin
I noticed that almost all architectures implemented exactly the same sys32_sysinfo... except parisc, where a bug was to be found in handling of the uptime. So let's remove a whole whack of code for fun and profit. Cribbed compat_sys_sysinfo from x86_64's implementation, since I figured it would be the best tested. This patch incorporates Arnd's suggestion of not using set_fs/get_fs, but instead extracting out the common code from sys_sysinfo.

2007-02-11[PATCH] relax check for AIX in msdos partition tableOlaf Hering
The patch to identify AIX disks and ignore them has caused at least one machine to fail to find the root partition on 2.6.19. The patch is: http://lkml.org/lkml/2006/7/31/117 The problem is some disk formatters do not blow away the first 4 bytes of the disk. If the disk we are installing to used to have AIX on it, then the first 4 bytes will still have IBMA in EBCDIC. The install in question was debian etch. Im not sure what the best fix is, perhaps the AIX detection code could check more than the first 4 bytes. The whole partition info for primary partitions is in this block: dd if=/dev/sdb count=$(( 4 * 16 )) bs=1 skip=$(( 0x1be )) All other data do not matter, beside the 0x55aa marker at the end of the first block.

2007-02-11[PATCH] add an RCU version of list splicingCorey Minyard
This patch is in support of the IPMI driver. I have tested this with the IPMI driver changes coming in the next patch. Add a list_splice_init_rcu() function to splice an RCU-protected list into another list. This takes the sync function as an argument, so one would do something like: INIT_LIST_HEAD(&list); list_splice_init_rcu(&source, &dest, synchronize_rcu); The idea being to keep the RCU API proliferation down to a dull roar.

2007-02-11[PATCH] use cycle_t instead of u64 in struct time_interpolatorHelge Deller
The 32bit and 64bit PARISC Linux kernels suffers from the problem, that the gettimeofday() call sometimes returns non-monotonic times. The easiest way to fix this, is to drop the PARISC-specific implementation and switch over to the generic TIME_INTERPOLATION framework. But in order to make it even compile on 32bit PARISC, the patch below which touches the generic Linux code, is mandatory. More information and the full patch with the parisc-specific changes is included in this thread: http://lists.parisc-linux.org/pipermail/parisc-linux/2006-December/031003.html As far as I could see, this patch does not change anything for the existing architectures which use this framework (IA64 and SPARC64), since "cycles_t" is defined there as unsigned 64bit-integer anyway (which then makes this patch a no-change for them).
