- Do not save/restore existing TLB entries, that is expensive, complicated, and does not really help performance much at all. - Only one unrolled loop for cheetah copy code. - For spitfire, use %asi register for block commit handling so we do not need two copies of the code.

We used to play games reporting the callers PC in certain functions such as the rwlock and atomic_t routines. If anything, somethin like this should be optional, not by default. Signed-off-by:

This also removes the ESPIPE logic from pipes and seq_files, since the VFS layer now supports it.

We need to set the thread priority to medium when entering all exceptions. We may have been executing in low priority (eg the idle loop), but definitely do not want to remain in that priority for the duration of the exception (eg a device interrupt). Signed-off-by:

Due to speculative execution, a CPU may execute some instructions after the rfid. This makes profiles confusing, since profiling ticks could end up in those instructions following the rfid that are never executed. Add a branch to self after each rfid to avoid this. Signed-off-by:

- Remove unused includes. - Be consistent about printing irq numbers, avoid a mix of decimal and hexadecimal. - Remove prototypes from xics.c, they should be in xics.h. - Remove infinite loop on failure, and instead use panic. Panic has a chance to log the error message on the LED panel and reboot the box, a while(1) loop does not. - xics isnt compiled for iseries any more, so no need for the CONFIG_PPC_PSERIES hack.

This patch just cleans up arch/ppc64/kernel/pci_dn.c a bit, including: - remove it from the iSeries build completely - small changes to Makefile - remove the "post" parameter from traverse_pci_devices as noone used it - make traverse_all_pci_devices static - remove CONFIG_PPC_PSERIES tests as we no longer build for iSeries - some reformatting (closer to "standard") - remove some of pointer casts This has been built (with default config) on pSeries and pmac and built and run on iSeries.

From: Art Haas <ahaas@airmail.net> The 1.3->1.4 changes to the arch/sparc/lib/copy_user.S file added parenthesis to a number of macros within that file. The BK changlog associated with this change indicate the change was to make the file work with gcc-3.3. When looking at the changes made, I see that similar macros exist in memcpy.S as well, so would a patch adding parens to that file be worthwhile? Also, just what was the problem with gcc-3.3 that was resolved by adding the parenthesis? Macro mis-expansion I'm guessing. Signed-off-by:
