Pull parisc fixes from Helge Deller: - The majority of lines changed are due to regenerated defconfig files. - The support for the Page Deallocation Table (PDT) which was merged in the merge window for 4.13 contained a bug which crashes the kernel if a bad page is reported by firmware. This is now fixed and the kernel messages will show which memory slot holds the broken DIMM. - Commit 3a166fc2 ("kbuild: handle libs-y archives separately from built-in.o archives") broke linking the parisc kernel due to millicode symbols which can't be reached then any longer. This was fixed by modifying the parisc vmlinux.lds linker script. - If the stack checker panics on stack overflow, avoid recursive panics. - Some parisc machines can't physically power off and thus instead start after some time to flood the console by presumably detected soft lockups. Avoid this by disabling the lockup detectors before entering the endless for-next loop. - Dave Anglin provided fixes which prevents TLB speculation on flushed pages on PA8800/PA9000 CPUs. - Arvind Yadav sent a trivial patch to constify the attribute_group structure in our firmware on-board-flash storage driver (pdc_stable.c) * 'parisc-4.13-3' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: parisc: Extend disabled preemption in copy_user_page parisc: Prevent TLB speculation on flushed pages on CPUs that only support equivalent aliases parisc: Suspend lockup detectors before system halt parisc: Show DIMM slot number which holds broken memory module parisc: Add function to return DIMM slot of physical address parisc: Fix crash when calling PDC_PAT_MEM PDT firmware function parisc: regenerate defconfig files parisc: pdc_stable: constify attribute_group structures. parisc: Merge millicode routines via linker script parisc: Disable further stack checks when panic occurs during stack check

Helge noticed that we flush the TLB page in flush_cache_page but not in flush_cache_range or flush_cache_mm. For a long time, we have had random segmentation faults building packages on machines with PA8800/8900 processors. These machines only support equivalent aliases. We don't see these faults on machines that don't require strict coherency. So, it appears TLB speculation sometimes leads to cache corruption on machines that require coherency. This patch adds TLB flushes to flush_cache_range and flush_cache_mm when coherency is required. We only flush the TLB in flush_cache_page when coherency is required. The patch also optimizes flush_cache_range. It turns out we always have the right context to use flush_user_dcache_range_asm and flush_user_icache_range_asm. The patch has been tested for some time on rp3440, rp3410 and A500-44. It's been boot tested on c8000. No random segmentation faults were observed during testing. Signed-off-by:

Commit c9c2877d ("parisc: Add Page Deallocation Table (PDT) support") introduced the pdc_pat_mem_read_pd_pdt() firmware helper function, which crashed the system because it trashed the stack if the pdc_pat_mem_read_pd_retinfo struct was located on the stack (and which is in size less than the required 32 64-bit values). Fix it by using the pdc_result struct instead when calling firmware and copy the return values back into the result struct when finished sucessfully. While debugging this code I noticed that the pdc_type wasn't set correctly either, so let's fix that too. Fixes: c9c2877d ("parisc: Add Page Deallocation Table (PDT) support") Signed-off-by:

In kernels with CONFIG_IWMMXT=y running on non-iWMMXt hardware, the signal frame can be left partially uninitialised in such a way that userspace cannot parse uc_regspace[] safely. In particular, this means that the VFP registers cannot be located reliably in the signal frame when a multi_v7_defconfig kernel is run on the majority of platforms. The cause is that the uc_regspace[] is laid out statically based on the kernel config, but the decision of whether to save/restore the iWMMXt registers must be a runtime decision. To minimise breakage of software that may assume a fixed layout, this patch emits a dummy block of the same size as iwmmxt_sigframe, for non-iWMMXt threads. However, the magic and size of this block are now filled in to help parsers skip over it. A new DUMMY_MAGIC is defined for this purpose. It is probably legitimate (if non-portable) for userspace to manufacture its own sigframe for sigreturn, and there is no obvious reason why userspace should be required to insert a DUMMY_MAGIC block when running on non-iWMMXt hardware, when omitting it has worked just fine forever in other configurations. So in this case, sigreturn does not require this block to be present. Reported-by:

Prepping for scripting the MAINTAINERS file cleanup (and possible split) showed a couple of cases where the headers for a couple of entries were bogus. There's a few different kinds of bogosities: - the X-GENE SOC EDAC case was confused and split over two lines - there were four entries for "GREYBUS PROTOCOLS DRIVERS" that were all different things. - the NOKIA N900 CAMERA SUPPORT" was duplicated all of which were more obvious when you started doing associative arrays in perl to track these things by the header (so that we can alphabetize this thing properly, and so that we might split it up by the data too).

When setting up the Xenstore watch for the memory target size the new watch will fire at once. Don't try to reach the configured target size by onlining new memory in this case, as the current memory size will be smaller in almost all cases due to e.g. BIOS reserved pages. Onlining new memory will lead to more problems e.g. undesired conflicts with NVMe devices meant to be operated as block devices. Instead remember the difference between target size and current size when the watch fires for the first time and apply it to any further size changes, too. In order to avoid races between balloon.c and xen-balloon.c init calls do the xen-balloon.c initialization from balloon.c. Signed-off-by:
