This patch provides a way to plug in an alternate, basic, and GPL'ed PMU subsystem to help with their monitoring needs or for specialty work. It can also be used in case of serious unexpected bugs in perfmon. Mutual exclusion between the two subsystems is guaranteed, hence no conflict can arise from both subsystem being present.

Older UltraSPARC-III chips have a P-Cache bug that makes us disable it by default at boot time. However, this does hurt performance substantially, particularly with memcpy(), and the bug is _incredibly_ obscure. I have never seen it triggered in practice, ever. So provide a "-P" boot option that forces the P-Cache on. It taints the kernel, so if it does trigger and cause some data corruption or OOPS, we will find out in the logs that this option was on when it happened. Signed-off-by: David S.

It may have been the case that the problem was first noticed to occur in a CONFIG_REGPARM compile. But it's not regparm functions that need not to make tail calls, it's asmlinkage functions called with a user pt_regs frame on the stack supplying their arguments. prevent_tail_call probably doesn't do anything at all in regparm functions (your argument registers are going to be clobbered, period). It was a braino to conditionalize that definition in the first place.

This fixes the compilation of some OSS drivers with GAMEPORT=n without the need to #if inside every single driver. This patch also removes the non-working and now obsolete SOUND_GAMEPORT. This patch is also an alternative solution for ALSA drivers with similar problems (but #if's inside the drivers might have the advantage of saving some more bytes of gameport is not available). The only user-visible change is that for GAMEPORT=m the affected OSS drivers are now allowed to be built statically (but they won't have gameport support).

Firstly, if the direction is TODEVICE, then dirty data in the streaming cache is impossible so we can elide the flush-flag synchronization in that case. Next, the context allocator is broken. It is highly likely that contexts get used multiple times for different dma mappings, which confuses the strbuf flushing code and makes it run inefficiently. Signed-off-by: David S.

It does the following things: - Workaround an issue in some Apple device-trees where a property may exist with the same name as a child node of the parent. We now simply "drop" the property instead of creating duplicate entries in /proc with random result... - Do not try to chop off the "@0" at the end of a node name whose unit address is 0. This is not useful, inconsistent, and the code was buggy and didn't always work anyway. - Do not create symlinks for the short name and unit address parts of a node. These were never really used, bloated the memory footprint of the device-tree with useless struct proc_dir_entry and their matching dentry and inode cache bloat. This results in smaller code, smaller memory footprint, and a more accurate view of the tree presented to userland.
