There are a whole bunch of reasons to use gettimeofday rather than rdtsc, so this patch does just that. Signed-off-by:

This patch saves and restores UML's idea of user mode across an interrupt. Without this, an interrupt arriving at the wrong time can cause UML to lose track of whether an interrupted handler is handing a userspace interrupt. From: Ingo Molnar Signed-off-by:

Fix a stupid bug in the sysrq handling in sn_console.c. Instead of eating all characters in the sysrq string (preventing them from getting to the tty layer), only eat those following 'ESC' since that's a pretty important character for various things. Please apply before 2.6.9 is released as the console is very unfriendly to use without it. Signed-off-by:

The following patch from Shaohua Li fixes a race with preempt enabled when a module containing a pm_idle callback is unloaded. Cached values in local variables need to be protected as RCU critical sections so that the synchronize_kernel() call in the unload path waits for all processors. There original bugzilla entry can be found at Shaohua, i had to make a small change (variable declaration after code in code block) so that it compiles with geriatric compilers such as the ones Andrew is attached to ;) http://bugzilla.kernel.org/show_bug.cgi?id=1716Signed-off-by:

SGI has been using this driver under Linux since 2001 but it was never included in the upstream kernel. SuSE did include the patch for mmtimer in SLES 9. The driver has been widely used for applications on the Altix platform. The timer hardware was designed around the multimedia timer specification by Intel but to my knowledge only SGI has implemented that standard. The driver was written by Jesse Barnes. The second revision has interrupt support removed and was somewhat simplified by removing one include file. Signed-off-by:

- Support new bootloader "m32r-g00ff". m32r-g00ff is newly written by NIIBE Yutaka and is released under GPL. http://www.gniibe.org/software/m32r-g00ff-20040729.tar.gz - arch/m32r/kernel/setup.c (parse_mem_cmdline): Fix to remove unused region at the end of memory. - include/asm-m32r/uaccess.h (__put_user_u64): Fix to remove warnings in compilation time. NOTE: (for m32r users) From this version, the bootloader-kernel interface has changed. - Section order is changed and rearranged for the new bootloader. - Kernel's entry address is also changed : 0x08001000 --> 0x08002000. - Paramter-passing method from bootloader to kernel is revised.

The useless iBCS2 supporting code is removed. However, according to old_ syscalls, I would like to keep backward- compatibility for a while, due to some old deb packages and executables for m32r.

A couple of GSM GPRS PCMCIA cards advertise 16 rather than 8 port sized windows for their serial interface. This breaks our current pcmcia serial driver which ignores any windows that are not 8 bytes. To avoid any regressions on other cards given this driver contains a certain amount of "magic" the patch below looks for 8 byte windows first so will not break existing supported cards (I hope ;)) Patch-by:

Currently metadata writing errors are ignored and not returned from sys_fsync on ext2 and ext3 filesystems. That is, at least ext2 and ext3. Both ext2 and ext3 resort to sync_inode() in their ->sync_inode method, which in turn calls ->write_inode. ->write_inode method has void type, and any IO errors happening inside are lost. Make ->write_inode return the error code? Signed-off-by:

From: James Cleverdon The value that cpuinfo returns for command 1 in ebx is the physical APIC ID latched when the system comes out of reset. Ordinarily, this is identical to the value in the local APIC's ID register, because nearly all BIOSes accept the HW assigned value. Our systems, made up of individual building blocks, can't do that. Each node boots as a separate system and is joined together by the BIOS. Thus, the BIOS rewrites the local APIC ID register with a new value. Potomac and Nocona chips have a mechanism by which the BIOS writer can change bits 7:5 to match the assigned cluster ID. Bits 2:0 come from the thread ID. However, bits 4:3 are still those latched at reset. Oops! Summary: Large clustered systems can't use cpuid to derive the sibling information. Fix: Use the local APIC ID. That's the value we use to online the CPUs, so it had better be OK. For non-clustered systems, cpuid == local APIC, so nothing but large boxes should be affected. Signed-off-by:
