* UBI: remove ubi_devices_cntArtem Bityutskiy2007-12-26

* UBI: create ubi_wl_entry slab on initializationArtem Bityutskiy2007-12-26
| | | | | | | Similarly to ltree_entry_slab, it makes more sense to create and destroy ubi_wl_entry slab on module initialization/exit. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBI: create ltree_entry slab on initializationArtem Bityutskiy2007-12-26
| | | | | | | | Since the ltree_entry slab cache is a global entity, which is used by all UBI devices, it is more logical to create it on module initialization time and destro on module exit time. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

* UBI: silence a warningJesper Juhl2007-12-26
| | | | | | | | | | | | | | | | | This patch silences the following warning : drivers/mtd/ubi/vmt.c:73: warning: 'ret' may be used uninitialized in this function gcc can't see that we always initialize ret in all situations where it is actually used. The one case where it's not initialized is when we BUG(), but gcc doesn't know that we won't then continue and use an uninitialized 'ret'. This patch results in code that does exactely the same as before, but it also makes gcc shut up, so we generate one less line of warning noise.

* UBI: add ubi_leb_map interfaceArtem Bityutskiy2007-12-26
| | | | | | | | | | | | | | The idea of this interface belongs to Adrian Hunter. The interface is extremely useful when one has to have a guarantee that an LEB will contain all 0xFFs even in case of an unclean reboot. UBI does have an 'ubi_leb_erase()' call which may do this, but it is stupid and ineffecient, because it flushes whole queue. I should be re-worked to just be a pair of unmap, map calls. The user of the interfaci is UBIFS at the moment. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBI: bugfix: allocate mandatory EBs firstArtem Bityutskiy2007-12-26
| | | | | | | | | First allocate the necessary eraseblocks, then the optional ones. Otherwise it allocates all PEBs for bad EB handling, and fails on then following EBA LEB allocation.

* UBI: fix error code in ubi_io_read()Artem Bityutskiy2007-12-26
| | | | | | | | | | | | | | | | | | | | When NAND detects an ECC error, it returns -EBADMSG. It does not stop reading requested data if one page has an ECC error, it keeps going and reads all the requested data. If it fails to read all the data, it does not return -EBADMSG, but returns the error code which reflects the reason of the failure. But some drivers may have bugs (e.g., OneNAND had) and stop reading after the first ECC error, so it returns -EBADMSG. In turn, UBI propagates this up to the caller. The caller will treat this as "all the requested data was read, but there was an ECC error". So we change the error code to -EIO if it is -EBADMSG and the read length is less then the requested length. We also add an assertion, so if UBI debugging is enabled, UBI will bug.

* [MTD] fix CONFIG_MTD_SHARP_SL if CONFIG_MTD=m Stanislav Brabec2007-11-28
| | | | | | | | | | | | | | | | | Sharp Zaurus SL-C3200 with CONFIG_MTD=m and CONFIG_MTD_SHARP_SL=y (as it is bool) lost support for the ROM flash. With CONFIG_MTD=y it has no problems. It is caused by losing of compiled code of drivers/mtd/maps/sharpsl-flash.o. It was linked to drivers/mtd/maps/built-in.o and drivers/mtd/built-in.o, but lost and not linked to drivers/built-in.o (because CONFIG_MTD!=y).

* [MTD] [NOR] Prevent erase command invocation on suspended chipAlexander Belyakov2007-11-26
| | | | | | | | | | | | | | | | | | | | | | while running stress tests we have met cfi_cmdset_0001.c driver issue. Working on multipartitional devices with erase suspend on write feature enabled it is possible to get erase operation invoked on chip with suspended erase. get_chip() looses information about earlier suspended erase and new erase operation gets issued. New erase operations report successful completion, but blocks remain dirty causing, for example, JFFS2 error messages like: ... Newly-erased block contained word 0x20031985 at offset 0x00200000 Newly-erased block contained word 0x20031985 at offset 0x00280000 Newly-erased block contained word 0x20031985 at offset 0x00240000 ...

* [JFFS2] Improve getdents vs. f_pos handling on NOR flash.David Woodhouse2007-11-01
| | | | | | | | | | | | | | | | | | Commit a491486a2087ac3dfc00efb4f838c8d684afaf54 started obliterating dirents directly on the medium, when jffs2_can_mark_obsolete(). Removing them immediately from the f->dents list, however, screws up handling of f_pos within a directory -- because the offset is equivalent to the number of entries through the list we are, and the existence of deletion dirents served to provide 'placeholders' for unlinked entries. Now, 'rm -r' doesn't even manage to unlink everything in the directory. Revert to keeping 'deletion' dirents in the list, at least in memory even though we no longer write anything to the medium.

It checks attributes in page structures and distinguishes necessary pages and unnecessary ones. To check them, makedumpfile gets the vmcoreinfo data which has the minimum debugging information only for dump filtering. For older x86_64 kernel (linux-2.6.23 or before), makedumpfile translates the virtual address of page structure into physical address by subtracting PAGE_OFFSET from virtual address, but this translation isn't effective for linux-2.6.24 sparsemem kernel, because its page structures are in virtual memmap area. makedumpfile should translate their virtual address by 4-levels paging and it needs the symbol "init_level4_pgt".

| * | x86: Fix boot protocol KEEP_SEGMENTS check.Eric W. Biederman2007-10-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The kernel only ever supports 1 version of the boot protocol so there is no need to check the boot protocol revision to see if a feature is supported. Both x86 and x86_64 support the same boot protocol so we need to implement the KEEP_SEGMENTS on x86_64 as well. It isn't just paravirt bootloaders that could use this functionality.
