The hostprogs need access to the CONFIG_* symbols found in include/generated/autoconf.h. But commit abbf1590 ("UAPI: Partition the header include path sets and add uapi/ header directories") replaced $(LINUXINCLUDE) with $(USERINCLUDE) which doesn't contain the necessary include paths. This has the undesirable effect of breaking the EFI boot stub because the #ifdef CONFIG_EFI_STUB code in arch/x86/boot/tools/build.c is never compiled. It should also be noted that because $(USERINCLUDE) isn't exported by the top-level Makefile it's actually empty in arch/x86/boot/Makefile. Cc: H.

As suggested by Andrew Morton: This is a pet peeve of mine. Any time there's a long list of items (header file inclusions, kconfig entries, array initalisers, etc) and someone wants to add a new item, they *always* go and stick it at the end of the list. Guys, don't do this. Either put the new item into a randomly-chosen position or, probably better, alphanumerically sort the list. lets sort all our select statements alphanumerically. This commit was created by the following perl: while (<>) { while (/\\\s*$/) { $_ .= <>; } undef %selects if /^\s*config\s+/; if (/^\s+select\s+(\w+).*/) { if (defined($selects{$1})) { if ($selects{$1} eq $_) { print STDERR "Warning: removing duplicated $1 entry\n"; } else { print STDERR "Error: $1 differently selected\n". "\tOld: $selects{$1}\n". "\tNew: $_\n"; exit 1; } } $selects{$1} = $_; next; } if (%selects and (/^\s*$/ or /^\s+help/ or /^\s+---help---/ or /^endif/ or /^endchoice/)) { foreach $k (sort (keys %selects)) { print "$selects{$k}"; } undef %selects; } print; } if (%selects) { foreach $k (sort (keys %selects)) { print "$selects{$k}"; } } It found two duplicates: Warning: removing duplicated S5P_SETUP_MIPIPHY entry Warning: removing duplicated HARDIRQS_SW_RESEND entry and they are identical duplicates, hence the shrinkage in the diffstat of two lines. We have four testers reporting success of this change (Tony, Stephen, Linus and Sekhar.)

getname() is intended to copy pathname strings from userspace into a kernel buffer. The result is just a string in kernel space. It would however be quite helpful to be able to attach some ancillary info to the string. For instance, we could attach some audit-related info to reduce the amount of audit-related processing needed. When auditing is enabled, we could also call getname() on the string more than once and not need to recopy it from userspace. This patchset converts the getname()/putname() interfaces to return a struct instead of a string. For now, the struct just tracks the string in kernel space and the original userland pointer for it. Later, we'll add other information to the struct as it becomes convenient. Signed-off-by: NJeff Layton <jlayton@redhat.com> Signed-off-by: NAl Viro <viro@zeniv.linux.org.uk>

* allow kernel_execve() leave the actual return to userland to caller (selected by CONFIG_GENERIC_KERNEL_EXECVE). Callers updated accordingly. * architecture that does select GENERIC_KERNEL_EXECVE in its Kconfig should have its ret_from_kernel_thread() do this: call schedule_tail call the callback left for it by copy_thread(); if it ever returns, that's because it has just done successful kernel_execve() jump to return from syscall IOW, its only difference from ret_from_fork() is that it does call the callback. * such an architecture should also get rid of ret_from_kernel_execve() and __ARCH_WANT_KERNEL_EXECVE This is the last part of infrastructure patches in that area - from that point on work on different architectures can live independently.

This fault was detected using the kgdb test suite on boot and it crashes recursively due to the fact that CONFIG_KPROBES on mips adds an extra die notifier in the page fault handler. The crash signature looks like this: kgdbts:RUN bad memory access test KGDB: re-enter exception: ALL breakpoints killed Call Trace: [<807b7548>] dump_stack+0x20/0x54 [<807b7548>] dump_stack+0x20/0x54 The fix for now is to have kgdb return immediately if the fault type is DIE_PAGE_FAULT and allow the kprobe code to decide what is supposed to happen.

Turn the slow side of work_pending into C function, including all the looping. What we get out of that: * we do _not_ call get_signal_to_deliver() with IRQs disabled anymore * no need to save/restore volatiles on each pass if there turns to be more than one (unlikely, but still) * all double-restart prevention is in C now. * glue gets simpler.

In case we have both NEED_RESCHED and SIGPENDING/NOTIFY_RESUME, handle the latter first. We'll get to original priorities in the next commit, but now that allows to simplify the treatment of NEED_RESCHED-only case nicely. Namely, now there no need to preserve the data for restarts across the call of schedule() in $work_resched; we can get there only if we had either returned from syscall without SIGPENDING (in which case we should've had no restart-worthy return value and want no restarts) or already got through do_notify_resume() call (in which case we want no restarts anymore). So we can just slap 0 into $19 instead of preserving it (and $20). Signed-off-by: NAl Viro <viro@zeniv.linux.org.uk>
