2006-03-14[PATCH] mtd_dataflash, fix block vs page eraseDavid Brownell1-1/+1
Fix a bug in the block-erase optimization for Dataflash; it was using block erase even for smaller segments that need page erase. That wouldn't matter for JFFS2, which never erases less than one block (sometimes several blocks), but for other callers it might.

2006-01-13[PATCH] spi: misc fixesDavid Brownell2-2/+4
This collects some small SPI patches that seem to be missing from the MM tree: - spi_butterfly kbuild hooks got dropped somehow; this restores them - quick fix for a (theoretical?) m25p80_write() oops noted by Andrew - quick fix for a potential config-specific oops for mtd_dataflash() - minor doc tweaks Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2006-01-13[PATCH] spi: use linked lists rather than an arrayVitaly Wool2-36/+42
This makes the SPI core and its users access transfers in the SPI message structure as linked list not as an array, as discussed on LKML. From: David Brownell <dbrownell@users.sourceforge.net> Updates including doc, bugfixes to the list code, add spi_message_add_tail(). Plus, initialize things _before_ grabbing the locks in some cases (in case it grows more expensive). This also merges some bitbang updates of mine that didn't yet make it into the mm tree.

2006-01-13[PATCH] spi: M25 series SPI flashMike Lavender3-0/+589
This was originally a driver for the ST M25P80 SPI flash. It's been updated slightly to handle other M25P series chips. For many of these chips, the specific type could be probed, but for now this just requires static setup with flash_platform_data that lists the chip type (size, format) and any default partitioning to use.

2006-01-13[PATCH] spi: mtd dataflash driverDavid Brownell3-0/+632
This is a conversion of the AT91rm9200 DataFlash MTD driver to use the lightweight SPI framework, and no longer be AT91-specific. It compiles down to less than 3KBytes on ARM. The driver allows board-specific init code to provide platform_data with the relevant MTD partitioning information, and hotplugs. This version has been lightly tested. Its parent at91_dataflash driver has been pretty well banged on, although kernel.org JFFS2 dataflash support was acting broken the last time I tried it.

2005-11-09[PATCH] changing CONFIG_LOCALVERSION rebuilds too much, for no good reasonOlaf Hering1-1/+0
This patch removes almost all inclusions of linux/version.h. The 3 #defines are unused in most of the touched files. A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is unfortunatly in linux/version.h. There are also lots of #ifdef for long obsolete kernels, this was not touched. In a few places, the linux/version.h include was move to where the LINUX_VERSION_CODE was used. quilt vi `find * -type f -name "*.[ch]"|xargs grep -El '(UTS_RELEASE|LINUX_VERSION_CODE|KERNEL_VERSION|linux/version.h)'|grep -Ev '(/(boot|coda|drm)/|~$)'` search pattern: /UTS_RELEASE\|LINUX_VERSION_CODE\|KERNEL_VERSION\|linux\/\(utsname\|version\).h Signed-off-by: Olaf Hering <olh@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-10-30[PATCH] fix missing includesTim Schmielau2-0/+2
I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

2005-09-10[PATCH] vfree and kfree cleanup in drivers/Jesper Juhl1-2/+1
This patch does a full cleanup of 'NULL checks before vfree', and a partial cleanup of calls to kfree for all of drivers/ - the kfree bit is partial in that I only did the files that also had vfree calls in them. The patch also gets rid of some redundant (void *) casts of pointers being passed to [vk]free, and a some tiny whitespace corrections also crept in.

2005-04-16Linux-2.6.12-rc2Linus Torvalds16-0/+8698
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
