Currently, if the GPMC driver fails to reserve memory when probed we will call BUG() and the kernel will not boot. Instead of calling BUG(), return an error from probe and allow kernel to boot. Boot tested on AM335x beagle bone board and OMAP4430 Panda board. V2 changes: - Ensure that clock and memory resources are released on error.

Previously the code only acquired spinlock after increasing / decreasing the usecount value, which is wrong. This leaves a small window where a task switch may occur between the check of the usecount and the actual wakeup / sleep of the domain. Fixed by moving the spinlock locking before the usecount access. Left the usecount as atomic_t if someone wants an easy access to the parameter through atomic_read.

s3c2440_clk_add is a subsys_interface method and calls clkdev_add_table, which is marked as __init. The modpost script complains about this because we must not call an __init function from a function in the .text section, and we cannot reference an __init function from a subsys_interface pointer. I have verified that the only code path into s3c2440_clk_add() is from "int __init s3c2440_init(void)", so s3c2440_clk_add can be marked __init_refok instead. Without this patch, building mini2440_defconfig results in: WARNING: vmlinux.o(.text+0x9848): Section mismatch in reference from the function s3c2440_clk_add() to the function .init.text:clkdev_add_table() The function s3c2440_clk_add() references the function __init clkdev_add_table(). This is often because s3c2440_clk_add lacks a __init annotation or the annotation of clkdev_add_table is wrong.

Commit 7d7e1eba (ARM: OMAP2+: Prepare for irqs.h removal) changed the interrupts to allow enabling sparse IRQ, but accidentally added the omap3 INTC base to the local IRQ. This causes the following: twd: can't register interrupt 45 (-22) twd_local_timer_register failed -22 The right fix is to not add any base, as it is a local timer. For the OMAP44XX_IRQ_LOCALWDT we had defined earlier there are no users, so no need to fix that.

Commit 9e3c0066 (ARM: dts: imx6q-arm2: add pinctrl for uart and enet) defines NANDF_CS pins as gpio in 'hog', assuming these two pins are always used by usdhc3 in gpio mode as card-detection and write-protection on ARM2 board. But it's not true. These pins are shared by usdhc3 and gpmi-nand. We should have the pins functional for gpmi-nand when usdhc3 is disabled. Move the pins out of 'hog', so that pins only work in gpio mode as CD and WP when usdhc3 is enabled, and otherwise they are available for gpmi-nand.

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.

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.

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>
