2008-12-04sparc: Add missing of_node_putNicolas Palix1-0/+2
of_node_put is needed before discarding a value received from of_find_node_by_name, eg in error handling code or when the device node is no longer used. The semantic match that catches the bug is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @r exists@ local idexpression struct device_node *n; position p1, p2; struct device_node *n1; statement S; identifier f; expression E; expression *ptr != NULL; @@ n@p1 = of_find_node_by_name(...) ... if (!n) S ... when != of_node_put(n) when != n1 = f(n,...) when != E = n when any when strict ( return \(0\|<+...n...+>\|ptr\); | return@p2 ...; | of_node_put(n); | n1 = f(n,...) | E = n ) @script:python@ p1 << r.p1; p2 << r.p2; @@ print "* file: %s of_find_node_by_name %s return %s" % (p1[0].file,p1[0].line,p2[0].line) // </smpl> Signed-off-by: Nicolas Palix <npalix@diku.dk> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: David S.

2008-10-07sparc32: sun4m interrupt mask cleanupRobert Reif1-54/+91
Here is an updated version of a patch I wrote 6 years ago http://marc.info/?l=linux-sparc&m=103939103607617&w=2 that simplifies interrupt mask lookup. It's main purpose is to add VME bus support but it's really a cleanup of the mask code. Signed-off-by: Robert Reif <reif@earthlink.net> Signed-off-by: David S. Miller <davem@davemloft.net>

This is the only use of the clear_profile_irq() btfixup entry, which just eats up lots of dead space on other platform types. A subsequent commit will delete the other implementations and the btfixup entry as well. Signed-off-by: David S. Miller <davem@davemloft.net>

2006-10-09IRQ: Use the new typedef for interrupt handler function pointersDavid Howells1-1/+1
Use the new typedef for interrupt handler function pointers rather than actually spelling out the full thing each time. This was scripted with the following small shell script: #!/bin/sh egrep -nHrl -e 'irqreturn_t[ ]*[(][*]' $* | while read i do echo $i perl -pi -e 's/irqreturn_t\s*[(]\s*[*]\s*([_a-zA-Z0-9]*)\s*[)]\s*[(]\s*int\s*,\s*void\s*[*]\s*[)]/irq_handler_t \1/g' $i || exit $? done Signed-Off-By: David Howells <dhowells@redhat.com>

2006-06-20[SPARC]: Kill __irq_itoa().David S. Miller1-8/+0
This ugly hack was long overdue to die. It was a way to print out Sparc interrupts in a more freindly format, since IRQ numbers were arbitrary opaque 32-bit integers which vectored into PIL levels. These 32-bit integers were not necessarily in the 0-->NR_IRQS range, but the PILs they vectored to were. The idea now is that we will increase NR_IRQS a little bit and use a virtual<-->real IRQ number mapping scheme similar to PowerPC. That makes this IRQ printing hack irrelevant, and furthermore only a handful of drivers actually used __irq_itoa() making it even less useful. Signed-off-by: David S. Miller <davem@davemloft.net>
2005-04-16Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds1-0/+399
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
