2007-02-14[PATCH] remove many unneeded #includes of sched.hTim Schmielau
After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

2007-02-12[PATCH] mark struct file_operations const 5Arjan van de Ven
Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

2007-02-09[MTD] remove unused ecctype,eccsize fields from struct mtd_infoArtem Bityutskiy
Remove unused and broken mtd->ecctype and mtd->eccsize fields from struct mtd_info. Do not remove them from userspace API data structures (don't want to breake userspace) but mark them as obsolete by a comment. Any userspace program which uses them should be half-broken anyway, so this is more about saving data structure size.

2007-02-09[MTD] [NOR] Intel: remove ugly PROGREGION macrosArtem Bityutskiy
Remove ugly and weird MTD_PROGREGION_CTRLMODE_VALID() and MTD_PROGREGION_CTRLMODE_INVALID() macros. There is only one user of them and they are used locally just for printing. Anyway, this patch is a preparation for removing mtd->ecctype and mtd->eccsize, but these macros use them. Fix this.

2007-02-09[MTD] OneNAND: Invalidate bufferRAM after eraseAdrian Hunter
OneNAND has internal bufferRAMs. The driver keeps track of what is in the bufferRAM to save having to load from the NAND core.

2007-02-09[MTD] [NAND] Correctly validate out-of-band offset and lengthAdrian Hunter
Add checks to ensure that out-of-band reads and writes are not attempted with an invalid offset or length. Specifically, the offset must be less than the size of oob for a page and the length must not go beyond the size of the device. Additionally the checks must adjust for auto-placement (MTD_OOB_AUTO) of oob data. Signed-off-by: Adrian Hunter <ext-adrian.hunter@nokia.com> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
2007-02-09[MTD] Fix default timeouts for Intel NOR flashDavid Woodhouse
In commit c172471b78255a5cf6d05383d9ebbf0c6683167a Nico switched to using common code for polling for command completion. Unfortunately he also used a common default timeout for both write and erase commands, despite the fact that erases can take a _whole_ lot longer. Use a more sensible default for erase timeout.

2007-02-09[MTD] OneNAND: Select correct chip's bufferRAM for DDPAdrian Hunter
OneNAND double-density package (DDP) has two chips, each with their own bufferRAM. The driver will skip loading data from the NAND core if the data can be found in a bufferRAM, however in that case, the correct chip's bufferRAM must be selected before reading from bufferRAM.

2007-02-07[MTD] OneNAND: Subpage write returned incorrect length writtenAdrian Hunter

2007-02-02[MTD] OneNAND: Reduce internal BufferRAM operationsKyungmin Park
It use blockpage instead of a pair (block, page). It can also cover a small chunk access. 0x00, 0x20, 0x40 and so on. And in JFFS2 behavior, sometimes it reads two pages alternatively. e.g., It first reads A page, B page and A page. So we check another bufferram to find requested page.

2007-01-25[MTD] OneNAND: Amend write-verify to compare to original bufferAdrian Hunter
When write-verify is enabled (CONFIG_MTD_ONENAND_VERIFY_WRITE), the data written is read back and compared. The comparison was being made between dataRAM buffers, but this does not verify that the data made it to the dataRAM correctly in the first place. This patch amends write-verify to compare back to the original buffer. It also now verifies sub-page writes.
