In fsl_rio_dbell_handler() the code currently simply acknowledges the QFI queue full interrupt, but does nothing to resolve the queue full condition. Instead, it jumps to the end of the isr. When a queue full condition occurs, the isr is then re-entered immediately and continually, forever. The fix is to just fall through and read out current doorbell entries. Signed-off-by:

Change the way how switchid value is set. Local counter variable does not provide unified way to identify switch devices in a system with multiple processors. Using local counter leads to the situation when the same RIO switch has different switch ID for each processor. Replacing local counter with unique portion of the Component Tag provides unified reference to the switch by every processor in the system. Signed-off-by:

Add setting links between rio_dev objects into the discovery process. This needed to report device connections on agent (non-host) processors that perform RIO discovery. Originally, these links have been introduced for enumerating host only to support error management. Signed-off-by:

Add definition of the unique device identifier field in the component tag. RIO_CTAG_UDEVID does not take all 32 bits of the component tag value to allow future extensions to the component tag use. Selected size of the RIO_CTAG_UDEVID field (17 bits) is sufficient to accommodate maximum number of endpoints in large RIO network (16-bit id) plus switches. Signed-off-by:

Convert RIO switches device structures (rio_dev + rio_switch) into a single allocation unit. This change is based on the fact that RIO switches are using common RIO device objects anyway. Allocating RIO switch objects as RIO devices with added space for switch information simplifies handling of RIO switch devices. Signed-off-by:

Alexandre Bounine authored
Change code to use one storage location common for switches and endpoints. This eliminates unnecessary device type checks during basic access operations. Logic that assigns destid to RIO devices stays unchanged - as before, switches use an associated destid because they do not have their own. Signed-off-by:

Commit 34aacb29 ("procfs: Use generic_file_llseek in /proc/kcore") broke seeking on /proc/kcore. This changes it back to use default_llseek in order to restore the original behavior. The problem with generic_file_llseek is that it only allows seeks up to inode->i_sb->s_maxbytes, which is 2GB-1 on procfs, where the memory file offset values in the /proc/kcore PT_LOAD segments may exceed or start beyond that offset value. A similar revert was made for /proc/vmcore. Signed-off-by:

Add a PageSlab() check before adding the _mapcount value to /kpagecount. page->_mapcount is in a union with the SLAB structure so for pages controlled by SLAB, page_mapcount() returns nonsense. Signed-off-by:

- ->low_ino is write-once field -- reading it under locks is unnecessary. - /proc/$PID stuff never reaches pde_put()/free_proc_entry() -- PROC_DYNAMIC_FIRST check never triggers. - in proc_get_inode(), inode number always matches proc dir entry, so save one parameter. Signed-off-by:

A call to va_start() must always be followed by a call to va_end() in the same function. In fs/reiserfs/prints.c::print_block() this is not always the case. If 'bh' is NULL we'll return without calling va_end(). One could add a call to va_end() before the 'return' statement, but it's nicer to just move the call to va_start() after the test for 'bh' being NULL. Signed-off-by:

Because GPIOs can have crucial functions especially in embedded systems, we are better safe than sorry regarding their configuration. For gpio_request, the documentation is simply enforced: <quote>"The return value of gpio_request() must be checked."</quote> For gpio_direction_* and gpio_request_*, we now act accordingly.
