2011-11-05watchdog: Add WDIOC_GETTIMELEFT ioctl support to w83627 watchdog driverGreg Lee1-6/+27

2011-11-05watchdog: Octeon: Mark octeon_wdt interrupt as IRQF_NO_THREADVenkat Subbiah1-1/+1
This is to exclude it from force threading to allow RT patch set to work. The watchdog timers are per-CPU and the addresses of register that reset the timer are calculated based on the current CPU. Therefore we cannot allow it to run on a thread on a different CPU. Also we only do a single register write, which is much faster than scheduling a handler thread. And while on this line remove IRQF_DISABLED as this flag is a NOP.

2011-11-05VFS: fix statfs() automounter semantics regressionDan McGee1-1/+1
No one in their right mind would expect statfs() to not work on a automounter managed mount point. Fix it. [ I'm not sure about the "no one in their right mind" part. It's not mounted, and you didn't ask for it to be mounted.

It would then unconditionally try return a flush completion via qib_send_complete() for an invalid wqe, or worse a valid one that is not queued. The panic results when the completion code tries to maintain an MR reference count for a NULL MR. This fix modifies logic to only send one completion per qib_make_rc_req() call and changing the completion status from IB_WC_SUCCESS to IB_WC_WR_FLUSH_ERR as the completions progress. The outer loop will call as many times as necessary to flush the queue.

2011-11-04IB/iser: DMA unmap TX bufs used for iSCSI/iSER headersOr Gerlitz2-4/+8

2011-11-04IB/iser: Use separate buffers for the login request/responseOr Gerlitz3-15/+52
The driver counted on the transactional nature of iSCSI login/text flows and used the same buffer for both the request and the response. We also went further and did DMA mapping only once, with DMA_FROM_DEVICE, which violates the DMA mapping API. Fix that by using different buffers, one for requests and one for responses, and use the correct DMA mapping direction for each.

2011-11-03net: add missing bh_unlock_sock() callsEric Dumazet2-0/+2
Simon Kirby reported lockdep warnings and following messages : [104661.897577] huh, entered softirq 3 NET_RX ffffffff81613740 preempt_count 00000101, exited with 00000102? [104661.923653] huh, entered softirq 3 NET_RX ffffffff81613740 preempt_count 00000101, exited with 00000102? Problem comes from commit 0e734419 (ipv4: Use inet_csk_route_child_sock() in DCCP and TCP.) If inet_csk_route_child_sock() returns NULL, we should release socket lock before freeing it. Another lock imbalance exists if __inet_inherit_port() returns an error since commit 093d282321da ( tproxy: fix hash locking issue when using port redirection in __inet_inherit_port()) a backport is also needed for >= 2.6.37 kernels.

2011-11-03arch/tile: factor out <arch/opcode.h> headerChris Metcalf15-4359/+4536
The kernel code was using some <asm> headers that included a mix of hardware-specific information (typically found in Tilera <arch> headers) and structures, enums, and function declarations supporting the disassembly function of the tile-desc.c sources. This change refactors that code so that a hardware-specific, but OS- and application-agnostic header, is created: <arch/opcode.h>. This header is then exported to userspace along with the other <arch> headers and can be used to build userspace code; in particular, it is used by glibc as part of implementing the backtrace() function. The new header, together with a header that specifically describes the disassembly code (<asm/tile-desc.h> with _32 and _64 variants), replaces the old <asm/opcode-tile*.h> and <asm/opcode_constants*.h> headers. As part of this change, we are also renaming the 32-bit constants from TILE_xxx to TILEPRO_xxx to better reflect the fact that they are specific to the TILEPro architecture, and not to TILE-Gx and any successor "tile" architecture chips.

2011-11-03arch/tile: add the <arch> headers to the set of installed kernel headersChris Metcalf2-0/+19
These headers are similar to the <asm> headers that describe kernel APIs, but instead describe aspects of the actual hardware in an OS- and application-independent manner. We need to include them in the set of installed headers so that userspace tools (including glibc) can build purely from the provided kernel headers. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>
2011-11-03arch/tile: avoid exporting a symbol no longer used by gccChris Metcalf1-2/+0
An earlier Tilera compiler generated calls to an "__ll_mul" function for long long multiplication. Our libgcc supported that as an alias for the normal __muldi3 routine, so we made it available to kernel modules as well. However, for a while now the compiler has internally been generating only the standard __muldi3 symbol, and the version we are giving back to the community does not have the __ll_mul alias, so we are removing it from the kernel too.

2011-11-03arch/tile: avoid ISO namespace pollution with <asm/sigcontext.h>Chris Metcalf2-35/+82
<asm/sigcontext.h> is used by glibc's <bits/sigcontext.h> from <signal.h>, which means that it can't clutter the namespace with random symbols or #defines. However, we use <arch/abi.h> to get a suitable type to hold a machine register. This change makes <arch/abi.h> safe to use in this kind of context if __need_int_reg_t is defined prior to including the file; in that case, it only defines a few symbols that are safe in the ISO namespace (prefixed with double underscores). <asm/sigcontext.h> then uses the __uint_reg_t type instead of the normal uint_reg_t.
