2008-10-13serial: allow 8250 to be used on sparcDavid Miller1-0/+6
This requires three changes: 1) Remove !SPARC restriction in Kconfig. 2) Move Sparc specific serial drivers before 8250, so that serial console devices don't change names on us, even if 8250 finds devices. 3) Since the Sparc specific serial drivers try to use the same major/minor device namespace as 8250, some coordination is necessary. Use the sunserial_*() layer routines to allocate minor number space within TTY_MAJOR when CONFIG_SPARC. This has no effect on other platforms. Thanks to Josip Rodin for bringing up this issue and testing plus debugging various revisions of this patch. Signed-off-by: David S.

2008-10-07sparc32: sun4m interrupt mask cleanupRobert Reif2-71/+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>

2008-09-12sparc64: Fix sparse warnings in fault.cDavid S. Miller1-0/+2
1) set_brkpt() is referenced by nothing and hasn't been used by anyone to my knowledge for many many years. So just delete it. 2) add extern decl for do_sparc64_fault() in asm/pgtable_64.h Signed-off-by: David S. Miller <davem@davemloft.net>

2008-09-11sparc64: Define WANT_PAGE_VIRTUALDavid S. Miller1-0/+2
As sparse warns, without this struct page pointer subtraction is extremely expensive, and this is a pretty common operation in fast paths. With this define struct page becomes 64 bytes which makes for a simple subtract and shift, instead of a costly divide or reciprocol multiply. Signed-off-by: David S. Miller <davem@davemloft.net>

2008-09-10sparc64: Get rid of pci_controller_info.David S. Miller1-0/+3

2008-09-08kernel/cpu.c: create a CPU_STARTING cpu_chain notifierManfred Spraul2-0/+3
Right now, there is no notifier that is called on a new cpu, before the new cpu begins processing interrupts/softirqs. Various kernel function would need that notification, e.g. kvm works around by calling smp_call_function_single(), rcu polls cpu_online_map. The patch adds a CPU_STARTING notification. It also adds a helper function that sends the message to all cpu_chain handlers. Tested on x86-64. All other archs are untested. Especially on sparc, I'm not sure if I got it right.
