2006-09-29[PATCH] uml: mechanical tidying after random MACs changeJeff Dike3-80/+40
Mechanical, hopefully non-functional changes stemming from setup_etheraddr always succeeding now that it always assigns a MAC, either from the command line or generated randomly: the test of the return of setup_etheraddr is removed, and code dependent on it succeeding is now unconditional setup_etheraddr can now be made void struct uml_net.have_mac is now always 1, so tests of it can be similarly removed, and uses of it can be replaced with 1 struct uml_net.have_mac is no longer used, so it can be removed struct uml_net_private.have_mac is copied from struct uml_net, so it is always 1 tests of uml_net_private.have_mac can be removed uml_net_private.have_mac can now be removed the only call to dev_ip_addr was removed, so it can be deleted It also turns out that setup_etheraddr is called only once, from the same file, so it can be static and its declaration removed from net_kern.h. Similarly, set_ether_mac is defined and called only from one file. Finally, setup_etheraddr and set_ether_mac were moved to avoid needing forward declarations.

2006-09-29[PATCH] uml: assign random MACs to interfaces if necessaryJeff Dike3-18/+46
Assign a random MAC to an ethernet interface if one was not provided on the command line. This became pressing when distros started bringing interfaces up before assigning IPs to them. The previous pattern of assigning an IP then bringing it up allowed the MAC to be generated from the first IP assigned. However, once the thing is up, it's probably a bad idea to change the MAC, so the MAC stayed initialized to fe:fd:0:0:0:0. Now, if there is no MAC from the command line, one is generated. We use the microseconds from gettimeofday (20 bits), plus the low 12 bits of the pid to seed the random number generator. random() is called twice, with 16 bits of each result used. I didn't want to have to try to fill in 32 bits optimally given an arbitrary RAND_MAX, so I just assume that it is greater than 65536 and use 16 bits of each random() return. There is also a bit of reformatting and whitespace cleanup here.

2006-09-29[PATCH] convert i386 Summit subarch to use SRAT info for apicid_to_node callskeith mannthey2-1/+11
Convert the i386 summit subarch apicid_to_node to use node information provided by the SRAT. It was discussed a little on LKML a few weeks ago and was seen as an acceptable fix. The current way of obtaining the nodeid static inline int apicid_to_node(int logical_apicid) { return logical_apicid >> 5; } is just not correct for all summit systems/bios. Assuming the apicid matches the Linux node number require a leap of faith that the bios mapped out the apicids a set way. Modern summit HW (IBM x460) does not layout its bios in the manner for various reasons and is unable to boot i386 numa. The best way to get the correct apicid to node information is from the SRAT table during boot. It lays out what apicid belongs to what node. I use this information to create a table for use at run time.

2006-09-28[ARM] nommu: confirms the CR_V bit in nommu modeHyok S. Choi3-1/+18
In nommu mode, the exception vector location depends on the platforms. Some of the implementations may have some special exception control forwarding method in their ROM/flash and for some of them has its own re-mapping mechanism by the h/w. This patch introduces a special configuration CONFIG_CPU_HIGH_VECTOR which turns on the CR_V bit in nommu mode. The CR_V bit is turned off by default.

Also, the Ethernet driver now uses the platform_device resources but doesn't yet use ioremap() so we need to pass it the virtual address instead of the physical address.

2006-09-28[S390] Inline assembly cleanup.Martin Schwidefsky17-457/+295
Major cleanup of all s390 inline assemblies. They now have a common coding style. Quite a few have been shortened, mainly by using register asm variables. Use of the EX_TABLE macro helps as well. The atomic ops, bit ops and locking inlines new use the Q-constraint if a newer gcc is used. That results in slightly better code. Thanks to Christian Borntraeger for proof reading the changes.

2006-09-28[S390] __div64_32 for 31 bit.Martin Schwidefsky3-0/+156
The clocksource infrastructure introduced with commit ad596171ed635c51a9eef829187af100cbf8dcf7 broke 31 bit s390. The reason is that the do_div() primitive for 31 bit always had a restriction: it could only divide an unsigned 64 bit integer by an unsigned 31 bit integer. The clocksource code now uses do_div() with a base value that has the most significant bit set. The result is that clock->cycle_interval has a funny value which causes the linux time to jump around like mad. The solution is "obvious": implement a proper __div64_32 function for 31 bit s390.

2006-09-27USB: pxa2xx_udc understands GPIO based VBUS sensingDavid Brownell1-14/+1
This updates the PXA 25x UDC board-independent infrastructure for VBUS sensing and the D+ pullup. The original code evolved from rather bizarre support on Intel's "Lubbock" reference hardware, so that on more sensible hardware it doesn't work as well as it could/should. The change is just to teach the UDC driver how to use built-in PXA GPIO pins directly. This reduces the amount of board-specfic object code needed, and enables the use of a VBUS sensing IRQ on boards (like Gumstix) that have one. With VBUS sensing, the UDC is unclocked until a host is actually connected. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
