These values were only introduced during this release cycle, so it is still early enough to get them right. alpha uses the same values that are in asm-generic/fcntl.h, so just remove them. parisc uses the values interchanged for no apparent reason, so remove them to give us consistency across all architectures.

1. At the end of smtc_distribute_timer, nextstamp is valid and has already passed so we goto repeat. 2. Nothing updates nextstamp (only updated if the timeout is in the future And we just decided it is in the past) 3. At the end nextstamp still has the same value so it is still valid and in the past. 4. This repeats until read_c0_count has a value which causes nextstamp to be in the future.

Since commit 22242681 ("MIPS: Extend COMMAND_LINE_SIZE"), CL_SIZE is 4096 and local array variables with this size will cause an build failure with default CONFIG_FRAME_WARN settings. Although current users of such array variables are all early bootstrap code and not likely to cause real stack overflow (thread_info corruption), it is preferable to to declare these arrays static with __initdata.

Running a 64-bit kernel on a 64-bit CPU without an FPU would cause the emulator to run in 32-bit mode. The c0_Status.FR bit is wired to zero on systems without an FPU, so using that bit to decide how the emulator behaves doesn't allow for proper emulation on 64-bit FPU-less processors. Instead, we need to select the emulator mode based on the user-space ABI. Since the thread flag TIF_32BIT_REGS is used to set c0_Status.FR, we can just use it to decide if the emulator should be in 32-bit or 64-bit mode.

On s390 there are two ways of specifying the system call number for the svc instruction. The standard way is to use the immediate field in the instruction (or to use EXecute for values unknown during assemble time). This can encode 256 system calls. The kernel ABI also allows to put the system call number in r1 and then execute svc 0 to enable system call numbers > 255. It turns out that single stepping svc 0 is broken, since the PER program check handler uses r1. We have to use a different register.

In a system where the ctrl-alt-del init action initiated by signal quiesce suspends the machine the quiesce handler override for _machine_restart, _machine_halt and _machine_power_off needs to be undone, otherwise the override is still present in the resumed system. The next shutdown would then load the quiesce state psw instead of performing the correct shutdown action. Signed-off-by: NMartin Schwidefsky <schwidefsky@de.ibm.com>

After an IPL from NSS the uptime of the system is incorrect. The reason is that the startup code in head.S is not executed in case of an IPL from NSS. Due to that sched_clock_base_cc which is used to initialze wall_to_monotonic contains the time stamp when the NSS has been created instead of the time stamp of the system start. Reinitialize the cputime accounting values in create_kernel_nss after the SAVESYS CP command that created the NSS segment. Signed-off-by: NMartin Schwidefsky <schwidefsky@de.ibm.com>

Normally is it not safe to allow a raid5 that is both dirty and degraded to be assembled without explicit request from that admin, as it can cause hidden data corruption. This is because 'dirty' means that the parity cannot be trusted, and 'degraded' means that the parity needs to be used. However, if the device that is missing contains only parity, then there is no issue and assembly can continue. This particularly applies when a RAID5 is being converted to a RAID6 and there is an unclean shutdown while the conversion is happening. So check for whether the degraded space only contains parity, and in that case, allow the assembly. Signed-off-by: NNeilBrown <neilb@suse.de>

When a reshape finds that it can add spare devices into the array, those devices might already be 'in_sync' if they are beyond the old size of the array, or they might not if they are within the array. The first case happens when we change an N-drive RAID5 to an N+1-drive RAID5. The second happens when we convert an N-drive RAID5 to an N+1-drive RAID6. So set the flag more carefully. Also, ->recovery_offset is only meaningful when the flag is clear, so only set it in that case. This change needs the preceding two to ensure that the non-in_sync device doesn't get evicted from the array when it is stopped, in the case where v0.90 metadata is used.

This is a combination that didn't really make sense before. However when a reshape is converting e.g. raid5 -> raid6, the extra device is not fully in-sync, but is certainly active and contains important data. So allow that start to be meaningful and in particular get the 'recovery_offset' value (which is needed for any non-in-sync active device) from the reshape_position.
