      "message": "linker script: unify usage of discard definition\n\nDiscarded sections in different archs share some commonality but have\nconsiderable differences.  This led to linker script for each arch\nimplementing its own /DISCARD/ definition, which makes maintaining\ntedious and adding new entries error-prone.\n\nThis patch makes all linker scripts to move discard definitions to the\nend of the linker script and use the common DISCARDS macro.  As ld\nuses the first matching section definition, archs can include default\ndiscarded sections by including them earlier in the linker script.\n\nia64 is notable because it first throws away some ia64 specific\nsubsections and then include the rest of the sections into the final\nimage, so those sections must be discarded before the inclusion.\n\ndefconfig compile tested for x86, x86-64, powerpc, powerpc64, ia64,\nalpha, sparc, sparc64 and s390.

It also adds a helper function\nthat sends the message to all cpu_chain handlers.\n\nTested on x86-64.\nAll other archs are untested.

      "message": "CONFIG_HIGHPTE vs. sub-page page tables.\n\nBackground: I\u0027ve implemented 1K/2K page tables for s390.  These sub-page\npage tables are required to properly support the s390 virtualization\ninstruction with KVM.  The SIE instruction requires that the page tables\nhave 256 page table entries (pte) followed by 256 page status table entries\n(pgste).  The pgstes are only required if the process is using the SIE\ninstruction.  The pgstes are updated by the hardware and by the hypervisor\nfor a number of reasons, one of them is dirty and reference bit tracking.\nTo avoid wasting memory the standard pte table allocation should return\n1K/2K (31/64 bit) and 2K/4K if the process is using SIE.\n\nProblem: Page size on s390 is 4K, page table size is 1K or 2K.  That means\nthe s390 version for pte_alloc_one cannot return a pointer to a struct\npage.  Trouble is that with the CONFIG_HIGHPTE feature on x86 pte_alloc_one\ncannot return a pointer to a pte either, since that would require more than\n32 bit for the return value of pte_alloc_one (and the pte * would not be\naccessible since its not kmapped).\n\nSolution: The only solution I found to this dilemma is a new typedef: a\npgtable_t.  For s390 pgtable_t will be a (pte *) - to be introduced with a\nlater patch.  For everybody else it will be a (struct page *).  The\nadditional problem with the initialization of the ptl lock and the\nNR_PAGETABLE accounting is solved with a constructor pgtable_page_ctor and\na destructor pgtable_page_dtor.  The page table allocation and free\nfunctions need to call these two whenever a page table page is allocated or\nfreed.  pmd_populate will get a pgtable_t instead of a struct page pointer.\n To get the pgtable_t back from a pmd entry that has been installed with\npmd_populate a new function pmd_pgtable is added.  It replaces the pmd_page\ncall in free_pte_range and apply_to_pte_range.\n\nSigned-off-by: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nCc: \u003clinux-arch@vger.kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

Not\nonly that, but under such conditions A.OUT core dumps are not produced either.\n\nTo make this work, this patch also does the following:\n\n (1) Makes the existence of the contents of linux/a.out.h contingent on\n     CONFIG_ARCH_SUPPORTS_AOUT.\n\n (2) Renames dump_thread() to aout_dump_thread() as it\u0027s only called by A.OUT\n     core dumping code.\n\n (3) Moves aout_dump_thread() into asm/a.out-core.h and makes it inline.  This\n     is then included only where needed.  This means that this bit of arch\n     code will be stored in the appropriate A.OUT binfmt module rather than\n     the core kernel.\n\n (4) Drops A.OUT support for Blackfin (according to Mike Frysinger it\u0027s not\n     needed) and FRV.\n\nThis patch depends on the previous patch to move STACK_TOP[_MAX] out of\nasm/a.out.h and into asm/processor.h as they\u0027re required whether or not A.OUT\nformat is available.\n\n[jdike@addtoit.com: uml: re-remove accidentally restored code]\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nCc: \u003clinux-arch@vger.kernel.org\u003e\nSigned-off-by: Jeff Dike \u003cjdike@linux.intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "uml: cover stubs with a VMA\n\nGive the stubs a VMA.  This allows the removal of a truly nasty kludge to make\nsure that mm-\u003enr_ptes was correct in exit_mmap.  The underlying problem was\nalways that the stubs, which have ptes, and thus allocated a page table,\nweren\u0027t covered by a VMA.\n\nThis patch fixes that by using install_special_mapping in arch_dup_mmap and\nactivate_context to create the VMA.  The stubs have to be moved, since\nshift_arg_pages seems to assume that the stack is the only VMA present at that\npoint during exec, and uses vma_adjust to fiddle its VMA.  However, that\nextends the stub VMA by the amount removed from the stack VMA.\n\nTo avoid this problem, the stubs were moved to a different fixed location at\nthe start of the address space.\n\nThe init_stub_pte calls were moved from init_new_context to arch_dup_mmap\nbecause I was occasionally seeing arch_dup_mmap not being called, causing\nexit_mmap to die.  Rather than figure out what was really happening, I decided\nit was cleaner to just move the calls so that there\u0027s no doubt that both the\npte and VMA creation happen, no matter what.  arch_exit_mmap is used to clear\nthe stub ptes at exit time.\n\nThe STUB_* constants in as-layout.h no longer depend on UM_TASK_SIZE, that\nthat definition is removed, along with the comments complaining about gcc.\n\nBecause the stubs are no longer at the top of the address space, some care is\nneeded while flushing TLBs.  update_pte_range checks for addresses in the stub\nrange and skips them.  flush_thread now issues two unmaps, one for the range\nbefore STUB_START and one for the range after STUB_END.\n\nSigned-off-by: Jeff Dike \u003cjdike@linux.intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "uml: kill processes instead of panicing kernel\n\nUML was panicing in the case of failures of libc calls which shouldn\u0027t happen.\n This is an overreaction since a failure from libc doesn\u0027t normally mean that\nkernel data structures are in an unknown state.  Instead, the current process\nshould just be killed if there is no way to recover.\n\nThe case that prompted this was a failure of PTRACE_SETREGS restoring the same\nstate that was read by PTRACE_GETREGS.  It appears that when a process tries\nto load a bogus value into a segment register, it segfaults (as expected) and\nthe value is actually loaded and is seen by PTRACE_GETREGS (not expected).\n\nThis case is fixed by forcing a fatal SIGSEGV on the process so that it\nimmediately dies.  fatal_sigsegv was added for this purpose.  It was declared\nas noreturn, so in order to pursuade gcc that it actually does not return, I\nadded a call to os_dump_core (and declared it noreturn) so that I get a core\nfile if somehow the process survives.\n\nAll other calls in arch/um/os-Linux/skas/process.c got the same treatment,\nwith failures causing the process to die instead of a kernel panic, with some\nexceptions.\n\nuserspace_tramp exits with status 1 if anything goes wrong there.  That will\ncause start_userspace to return an error.  copy_context_skas0 and\nmap_stub_pages also now return errors instead of panicing.  Callers of thes\nfunctions were changed to check for errors and do something appropriate.\nUsually that\u0027s to return an error to their callers.\ncheck_skas3_ptrace_faultinfo just exits since that\u0027s too early to do anything\nelse.\n\nsave_registers, restore_registers, and init_registers now return status\ninstead of panicing on failure, with their callers doing something\nappropriate.\n\nThere were also duplicate declarations of save_registers and restore_registers\nin os.h - these are gone.\n\nI noticed and fixed up some whitespace damage.\n\nSigned-off-by: Jeff Dike \u003cjdike@linux.intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

Its declarations in pgtable.h and ksyms.c are also\ngone.\n\ncurrent_cmd was another apparent user, but it itself isn\u0027t used, so it\nis deleted.\n\nSigned-off-by: Jeff Dike \u003cjdike@linux.intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"
