random: make get_random_int() more random It's a really simple patch that basically just open-codes the current "secure_ip_id()" call, but when open-coding it we now use a _static_ hashing area, so that it gets updated every time. And to make sure somebody can't just start from the same original seed of all-zeroes, and then do the "half_md4_transform()" over and over until they get the same sequence as the kernel has, each iteration also mixes in the same old "current->pid + jiffies" we used - so we should now have a regular strong pseudo-number generator, but we also have one that doesn't have a single seed. Note: the "pid + jiffies" is just meant to be a tiny tiny bit of noise. It has no real meaning. It could be anything. I just picked the previous seed, it's just that now we keep the state in between calls and that will feed into the next result, and that should make all the difference. I made that hash be a per-cpu data just to avoid cache-line ping-pong: having multiple CPU's write to the same data would be fine for randomness, and add yet another layer of chaos to it, but since get_random_int() is supposed to be a fast interface I did it that way instead. I considered using "__raw_get_cpu_var()" to avoid any preemption overhead while still getting the hash be _mostly_ ping-pong free, but in the end good taste won out.

[ARM] 5507/1: support R_ARM_MOVW_ABS_NC and MOVT_ABS relocation types From: Bruce Ashfield <bruce.ashfield@windriver.com> To fully support the armv7-a instruction set/optimizations, support for the R_ARM_MOVW_ABS_NC and R_ARM_MOVT_ABS relocation types is required. The MOVW and MOVT are both load-immediate instructions, MOVW loads 16 bits into the bottom half of a register, and MOVT loads 16 bits into the top half of a register. The relocation information for these instructions has a full 32 bit value, plus an addend which is stored in the 16 immediate bits in the instruction itself. The immediate bits in the instruction are not contiguous (the register # splits it into a 4 bit and 12 bit value), so the addend has to be extracted accordingly and added to the value. The value is then split and put into the instruction; a MOVW uses the bottom 16 bits of the value, and a MOVT uses the top 16 bits.

md: remove rd%d links immediately after stopping an array. md maintains link in sys/mdXX/md/ to identify which device has which role in the array. e.g. rd2 -> dev-sda indicates that the device with role '2' in the array is sda. These links are only present when the array is active. They are created immediately after ->run is called, and so should be removed immediately after ->stop is called. However they are currently removed a little bit later, and it is possible for ->run to be called again, thus adding these links, before they are removed. So move the removal earlier so they are consistently only present when the array is active.

md: remove ability to explicit set an inactive array to 'clean'. Being able to write 'clean' to an 'array_state' of an inactive array to activate it in 'clean' mode is both unnecessary and inconvenient. It is unnecessary because the same can be achieved by writing 'active'. This activates and array, but it still remains 'clean' until the first write. It is inconvenient because writing 'clean' is more often used to cause an 'active' array to revert to 'clean' mode (thus blocking any writes until a 'write-pending' is promoted to 'active'). Allowing 'clean' to both activate an array and mark an active array as clean can lead to races: One program writes 'clean' to mark the active array as clean at the same time as another program writes 'inactive' to deactivate (stop) and active array. Depending on which writes first, the array could be deactivated and immediately reactivated which isn't what was desired. So just disable the use of 'clean' to activate an array. This avoids a race that can be triggered with mdadm-3.0 and external metadata, so it suitable for -stable.

md: tidy up status_resync to handle large arrays. Two problems in status_resync. 1/ It still used Kilobytes as the basic block unit, while most code now uses sectors uniformly. 2/ It doesn't allow for the possibility that max_sectors exceeds the range of "unsigned long". So - change "max_blocks" to "max_sectors", and store sector numbers in there and in 'resync' - Make 'rt' a 'sector_t' so it can temporarily hold the number of remaining sectors. - use sector_div rather than normal division. - change the magic '100' used to preserve precision to '32'. + making it a power of 2 makes division easier + it doesn't need to be as large as it was chosen when we averaged speed over the entire run. Now we average speed over the last 30 seconds or so.

md: fix some (more) errors with bitmaps on devices larger than 2TB. If a write intent bitmap covers more than 2TB, we sometimes work with values beyond 32bit, so these need to be sector_t. This patches add the required casts to some unsigned longs that are being shifted up. This will affect any raid10 larger than 2TB, or any raid1/4/5/6 with member devices that are larger than 2TB.

md/raid10: don't clear bitmap during recovery if array will still be degraded. If we have a raid10 with multiple missing devices, and we recover just one of these to a spare, then we risk (depending on the bitmap and array chunk size) clearing bits of the bitmap for which recovery isn't complete (because a device is still missing). This can lead to a subsequent "re-add" being recovered without any IO happening, which would result in loss of data. This patch takes the safe approach of not clearing bitmap bits if the array will still be degraded. This patch is suitable for all active -stable kernels.

md: fix loading of out-of-date bitmap. When md is loading a bitmap which it knows is out of date, it fills each page with 1s and writes it back out again. However the write_page call makes used of bitmap->file_pages and bitmap->last_page_size which haven't been set correctly yet. So this can sometimes fail. Move the setting of file_pages and last_page_size to before the call to write_page. This bug can cause the assembly on an array to fail, thus making the data inaccessible. Hence I think it is a suitable candidate for -stable.
