This unbreaks kexec support. Without this fix all cases of kexec fails since __pa() does not behave like PHYSADDR(). The downside is that we also kill the code blocking users running old kexec-tools. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

This patch adds an MFD driver for the SuperH Mobile SDHI hardware block. At this point the driver simply wraps the tmio-mmc driver with some clock code.

When CONFIG_FUNCTION_GRAPH_TRACER is enabled the function graph tracer may patch return addresses on the stack with the address of return_to_handler(). This really confuses the DWARF unwinder because it will try find the caller of return_to_handler(), not the caller of the real return address. So teach the DWARF unwinder how to find the real return address whenever it encounters return_to_handler(). This patch does not cope very well when multiple return addresses on the stack have been patched. To make it work properly it would require state to track how many return_to_handler()'s have been seen so that we'd know where to look in current->curr_ret_stack[]. So for now, instead of trying to handle this, just moan if more than one return address on the stack has been patched.

This adds an __irq_entry annotation for do_IRQ() so that the IRQ annotation in the function graph tracer works as advertized. We already have the IRQENTRY section wired up, so this is just a trivial addition to actually make use of it. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

Rusty, commit 3ca4f5ca virtio: add virtio IDs file moved all device IDs into a single file. While the change itself is a very good one, it can break userspace applications. For example if a userspace tool wanted to get the ID of virtio_net it used to include virtio_net.h. This does no longer work, since virtio_net.h does not include virtio_ids.h. This patch moves all "#include <linux/virtio_ids.h>" from the C files into the header files, making the header files compatible with the old ones. In addition, this patch exports virtio_ids.h to userspace.

It seems like the addition of QUEUE_FLAG_VIRT caueses major performance regressions for Fedora users: https://bugzilla.redhat.com/show_bug.cgi?id=509383 https://bugzilla.redhat.com/show_bug.cgi?id=505695 while I can't reproduce those extreme regressions myself I think the flag is wrong. Rationale: QUEUE_FLAG_VIRT expands to QUEUE_FLAG_NONROT which casus the queue unplugged immediately. This is not a good behaviour for at least qemu and kvm where we do have significant overhead for every I/O operations. Even with all the latested speeups (native AIO, MSI support, zero copy) we can only get native speed for up to 128kb I/O requests we already are down to 66% of native performance for 4kb requests even on my laptop running the Intel X25-M SSD for which the QUEUE_FLAG_NONROT was designed. If we ever get virtio-blk overhead low enough that this flag makes sense it should only be set based on a feature flag set by the host.

This patch fixes a null pointer exception in pipe_rdwr_open() which generates the stack trace: > Unable to handle kernel NULL pointer dereference at 0000000000000028 RIP: > [<ffffffff802899a5>] pipe_rdwr_open+0x35/0x70 > [<ffffffff8028125c>] __dentry_open+0x13c/0x230 > [<ffffffff8028143d>] do_filp_open+0x2d/0x40 > [<ffffffff802814aa>] do_sys_open+0x5a/0x100 > [<ffffffff8021faf3>] sysenter_do_call+0x1b/0x67 The failure mode is triggered by an attempt to open an anonymous pipe via /proc/pid/fd/* as exemplified by this script: ============================================================= while : ; do { echo y ; sleep 1 ; } | { while read ; do echo z$REPLY; done ; } & PID=$! OUT=$(ps -efl | grep 'sleep 1' | grep -v grep | { read PID REST ; echo $PID; } ) OUT="${OUT%% *}" DELAY=$((RANDOM * 1000 / 32768)) usleep $((DELAY * 1000 + RANDOM % 1000 )) echo n > /proc/$OUT/fd/1 # Trigger defect done ============================================================= Note that the failure window is quite small and I could only reliably reproduce the defect by inserting a small delay in pipe_rdwr_open(). For example: static int pipe_rdwr_open(struct inode *inode, struct file *filp) { msleep(100); mutex_lock(&inode->i_mutex); Although the defect was observed in pipe_rdwr_open(), I think it makes sense to replicate the change through all the pipe_*_open() functions. The core of the change is to verify that inode->i_pipe has not been released before attempting to manipulate it. If inode->i_pipe is no longer present, return ENOENT to indicate so. The comment about potentially using atomic_t for i_pipe->readers and i_pipe->writers has also been removed because it is no longer relevant in this context. The inode->i_mutex lock must be used so that inode->i_pipe can be dealt with correctly.

In ks8851_set_rx_mode() the case handling IFF_MULTICAST was also setting the RXCR1_AE bit by accident. This meant that all unicast frames where being accepted by the device. Remove RXCR1_AE from this case. Note, RXCR1_AE was also masking a problem with setting the MAC address properly, so needs to be applied after fixing the MAC write order. Fixes a bug reported by Doong, Ping of Micrel. This version of the patch avoids setting RXCR1_ME for all cases. Signed-off-by: Ben Dooks <ben@simtec.co.uk> Signed-off-by: David S.

Mask off FS_EVENT_ON_CHILD in dnotify_handle_event(). Otherwise, when there is more than one watch on a directory and dnotify_should_send_event() succeeds, events with FS_EVENT_ON_CHILD set will trigger all watches and cause spurious events.

When renaming kernel_fpu_using to irq_fpu_usable, the semantics of the function is changed too, from mesuring whether kernel is using FPU, that is, the FPU is NOT available, to measuring whether FPU is usable, that is, the FPU is available. But the usage of irq_fpu_usable in aesni-intel_glue.c is not changed accordingly. This patch fixes this.
