Remove the limitation of PAGE_SIZE to be 4k by defining the own page size and macros for 4k. 8kb page size could be natively supported, but it's disabled right now for simplicity. Also, clean up using upper_32_bits() macro. Signed-off-by:

The device seems supporting only U8, S16, S24_3LE, S32. Other linear formats result in bad outputs. Also, added the support for 32bit float format, which wasn't listed in the original code. Signed-off-by:

Tim Starling reported that crashdump will panic with kernel compiled with CONFIG_KEXEC_JUMP due to null pointer deference in machine_kexec_32.c: machine_kexec(), when deferencing kexec_image. Refering to: http://bugzilla.kernel.org/show_bug.cgi?id=13265 This patch fixes the BUG via replacing global variable reference: kexec_image in machine_kexec() with local variable reference: image, which is more appropriate, and will not be null. Same BUG is in machine_kexec_64.c too, so fixed too in the same way. [ Impact: fix crash on kexec ] Reported-by:

With the introduction of the .brk section, special care must be taken that no unused page table entries remain if _brk_end and _end are separated by a 2M page boundary. cleanup_highmap() runs very early and hence cannot take care of that, hence potential entries needing to be removed past _brk_end must be cleared once the brk allocator has done its job.

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. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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. Reported-by:

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. Reported-by:
