Introduce a top-level 's390' directory which should be used when adding new s390 specific debug feature files and/or directories. This makes hopefully sure that the contents of the s390 directory will be a bit more structured. Right now we have a couple of top-level files where it is not easy to tell to which subsystem they belong to.

User space needs some information about the secure key(s) before actually invoking the pkey and/or paes funcionality. This patch introduces a new ioctl API and in kernel API to verify the the secure key blob and give back some information about the key (type, bitsize, old MKVP). Both APIs are described in detail in the header files arch/s390/include/asm/pkey.h and arch/s390/include/uapi/asm/pkey.h.

If running within a level 3 hypervisor, the hypervisor provides a SYSIB block which contains a control program indentifier string. Use this string instead of the simple KVM and z/VM strings only. In case of z/VM this provides addtional information: the z/VM version. The new string looks similar to this: Hardware name: IBM 2964 N96 702 (z/VM 6.4.0) Signed-off-by: NHeiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: NMartin Schwidefsky <schwidefsky@de.ibm.com>

The arch description provided for the "Hardware name:" contains lots of extra whitespace due to the way the SYSIB contents are defined (strings aren't zero terminated). This looks a bit odd and therefore remove the extra whitespace characters. This also gives the opportunity to add more information, if required, without hitting the magic 80 characters per line limit.

__GFP_REPEAT has a rather weak semantic but since it has been introduced around 2.6.12 it has been ignored for low order allocations. page_table_alloc then uses the flag for a single page allocation. This means that this flag has never been actually useful here because it has always been used only for PAGE_ALLOC_COSTLY requests. An earlier attempt to remove the flag 10d58bf2 ("s390: get rid of superfluous __GFP_REPEAT") has missed this one but the situation is very same here.

Commit af51160e ("s390/smp: initialize cpu_present_mask in setup_arch") initializes the cpu_present_mask much earlier than before. However the cpu detection code relies on the fact that iff logical cpu 0 is marked present then also the corresponding physical cpu address within the pcpu_devices array slot is valid. Since commit 44fd2299 ("[PATCH] Register the boot-cpu in the cpu maps earlier") this assumption is not true anymore. The patch marks logical cpu 0 as present in common code without that architecture code had a chance to setup the logical to physical map. With that change the cpu detection code assumes that the physical cpu address of cpu 0 is also 0, which is not necessarily true. Subsequently the physical cpu address of the ipl cpu will be mapped to a different logical cpu. If that cpu is brought online later the ipl cpu will send itself an initial cpu reset sigp signal. This in turn completely resets the ipl cpu and the system stops working. A dump of such a system looks like a "store status" has been forgotten. But actually the kernel itself removed all traces which would allow to easily tell what went wrong. To fix this initialize the logical to physical cpu address already in smp_setup_processor_id(). In addition remove the initialization of the cpu_present_mask and cpu_online_mask for cpu 0, since that has already been done. Also add a sanity check, just in case common code will be changed again... The problem can be easily reproduced within a z/VM guest: > chcpu -d 0 > vmcp ipl Fixes: af51160e ("s390/smp: initialize cpu_present_mask in setup_arch") Reported-by: NSebastian Ott <sebott@linux.vnet.ibm.com> Signed-off-by: NHeiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: NMartin Schwidefsky <schwidefsky@de.ibm.com>

Reorder the operations in decompress_kernel() to ensure initrd is moved to a safe location before the bss section is zeroed. During decompression bss can overlap with the initrd and this can corrupt the initrd contents depending on the size of the compressed kernel (which affects where the initrd is placed by the bootloader) and the size of the bss section of the decompressor. Also use the correct initrd size when checking for overlaps with parmblock.

This adds a new system call to enable the use of guarded storage for user space processes. The system call takes two arguments, a command and pointer to a guarded storage control block: s390_guarded_storage(int command, struct gs_cb *gs_cb); The second argument is relevant only for the GS_SET_BC_CB command. The commands in detail: 0 - GS_ENABLE Enable the guarded storage facility for the current task. The initial content of the guarded storage control block will be all zeros. After the enablement the user space code can use load-guarded-storage-controls instruction (LGSC) to load an arbitrary control block. While a task is enabled the kernel will save and restore the current content of the guarded storage registers on context switch. 1 - GS_DISABLE Disables the use of the guarded storage facility for the current task. The kernel will cease to save and restore the content of the guarded storage registers, the task specific content of these registers is lost. 2 - GS_SET_BC_CB Set a broadcast guarded storage control block. This is called per thread and stores a specific guarded storage control block in the task struct of the current task. This control block will be used for the broadcast event GS_BROADCAST. 3 - GS_CLEAR_BC_CB Clears the broadcast guarded storage control block. The guarded- storage control block is removed from the task struct that was established by GS_SET_BC_CB. 4 - GS_BROADCAST Sends a broadcast to all thread siblings of the current task. Every sibling that has established a broadcast guarded storage control block will load this control block and will be enabled for guarded storage. The broadcast guarded storage control block is used up, a second broadcast without a refresh of the stored control block with GS_SET_BC_CB will not have any effect.

Both nat_bits cache and free_nid_bitmap cache provide same functionality as a intermediate cache between free nid cache and disk, but with different granularity of indicating free nid range, and different persistence policy. nat_bits cache provides better persistence ability, and free_nid_bitmap provides better granularity. In this patch we combine advantage of both caches, so finally policy of the intermediate cache would be: - init: load free nid status from nat_bits into free_nid_bitmap - lookup: scan free_nid_bitmap before load NAT blocks - update: update free_nid_bitmap in real-time - persistence: udpate and persist nat_bits in checkpoint This patch also resolves performance regression reported by lkp-robot. commit: 4ac91242 ("f2fs: introduce free nid bitmap") d00030cf9cd0bb96fdccc41e33d3c91dcbb672ba ("f2fs: use __set{__clear}_bit_le") 1382c0f3f9d3f936c8bc42ed1591cf7a593ef9f7 ("f2fs: combine nat_bits and free_nid_bitmap cache") 4ac91242 d00030cf9cd0bb96fdccc41e33 1382c0f3f9d3f936c8bc42ed15 ---------------- -------------------------- -------------------------- %stddev %change %stddev %change %stddev \ | \ | \ 77863 ± 0% +2.1% 79485 ± 1% +50.8% 117404 ± 0% aim7.jobs-per-min 231.63 ± 0% -2.0% 227.01 ± 1% -33.6% 153.80 ± 0% aim7.time.elapsed_time 231.63 ± 0% -2.0% 227.01 ± 1% -33.6% 153.80 ± 0% aim7.time.elapsed_time.max 896604 ± 0% -0.8% 889221 ± 3% -20.2% 715260 ± 1% aim7.time.involuntary_context_switches 2394 ± 1% +4.6% 2503 ± 1% +3.7% 2481 ± 2% aim7.time.maximum_resident_set_size 6240 ± 0% -1.5% 6145 ± 1% -14.1% 5360 ± 1% aim7.time.system_time 1111357 ± 3% +1.9% 1132509 ± 2% -6.2% 1041932 ± 2% aim7.time.voluntary_context_switches ...

This BUG_ON() triggered for me once at shutdown, and I don't see a reason for the check. The code correctly checks whether the swap slot cache is usable or not, so an uninitialized swap slot cache is not actually problematic afaik. I've temporarily just switched the BUG_ON() to a WARN_ON_ONCE(), since I'm not sure why that seemingly pointless check was there. I suspect the real fix is to just remove it entirely, but for now we'll warn about it but not bring the machine down.

One fix is for -stable to address pmd-to-pte fallback from the original implementation, another fix is for the new (introduced in 4.11-rc1) pud-to-pmd regression, and a typo fix comes along for the ride. These have received a build success notification from the kbuild robot" * 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: device-dax: fix debug output typo device-dax: fix pud fault fallback handling device-dax: fix pmd/pte fault fallback handling
