In arch/x86/boot/printf.c gets rid of unused tail of digits: const char *digits = "0123456789abcdefghijklmnopqrstuvwxyz"; (we are using 0-9a-f only) Uses smaller/faster lowercasing (by ORing with 0x20) if we know that we work on numbers/digits. Makes strtoul smaller, and also we are getting rid of static const char small_digits[] = "0123456789abcdefx"; static const char large_digits[] = "0123456789ABCDEFX"; since this works equally well: static const char digits[16] = "0123456789ABCDEF"; Size savings: $ size vmlinux.org vmlinux text data bss dec hex filename 877320 112252 90112 1079684 107984 vmlinux.org 877048 112252 90112 1079412 107874 vmlinux It may be also a tiny bit faster because code has less branches now, but I doubt it is measurable.

Specifically the boot time page tables in a CONFIG_X86_PAE=y enabled kernel are in PAE format. early_ioremap is updated to use the standard page table accessors. Clear any mappings beyond max_low_pfn from the boot page tables in native_pagetable_setup_start because the initial mappings can extend beyond the range of physical memory and into the vmalloc area. Derived from patches by Eric Biederman and H. Peter Anvin. [ jeremy@goop.org: PAE swapper_pg_dir needs to be page-sized fix ] Signed-off-by:

Add function definition and extern variables to asm-x86/acpi.h. All of these are used in bus.c in ifdef(CONFIG_X86) sections, so are only added to the x86 include headers. boot.c already includes acpi.h so no changes are needed there.

Each AMD Geode MFGPT timer interrupt output is paired with another timer; esentially the interrupt goes if either timer fires. This is okay, but the handlers need to be aware of this. Make sure in the timer tick handler that our timer really did expire. Signed-off-by:

We *really* don't want to be reading MFGPTx_SETUP and writing back those values. What we want to be doing is clearing CMP1 and CMP2 unconditionally; otherwise, we have races where CMP1 and/or CMP2 fire after we've read MFGPTx_SETUP. They can also fire between when we've written ~CNTEN to the register, and when the new register values get copied to the timer's version of the register. By clearing both fields, we're okay.

There isn't much value to always detecting the MFGPT timers on Geode platforms; detection is only needed when something wants to use the timers. Move the detection code so that it gets called the first time a timer is allocated. Signed-off-by:

We had planned to use the 'owner' field for allowing re-allocation of MFGPTs; however, doing it by module owner name isn't flexible enough. So, drop this for now. If it turns out that we need timers in modules, we'll need to come up with a scheme that matches the write-once fields of the MFGPTx_SETUP register, and drops ponies from the sky. Signed-off-by:

The GEODE MFGPT code assumed that 32kHz was 32000 Hz while the boards run on a 32.768 kHz digital watch crystal. In practise, it will not change the timer's frequency as the skew was only 2.4%, but it should provide more accurate intervals. Signed-off-by:

mm_cgroup() is exclusively used to test whether an mm's mem_cgroup pointer is pointing to a specific cgroup. Instead of returning the pointer, we can just do the test itself in a new macro: vm_match_cgroup(mm, cgroup) returns non-zero if the mm's mem_cgroup points to cgroup. Otherwise it returns zero.

Presumably this also means it has no ptes too, right? In which case, it's better to comment the whole function out. Then when someone tries to ask the above meaningless question, they get a compile error rather than a meaningless answer. Signed-off-by:

Add support for different number of page table levels dependent on the highest address used for a process. This will cause a 31 bit process to use a two level page table instead of the four level page table that is the default after the pud has been introduced. Likewise a normal 64 bit process will use three levels instead of four. Only if a process runs out of the 4 tera bytes which can be addressed with a three level page table the fourth level is dynamically added. Then the process can use up to 8 peta byte. Signed-off-by: -

There are two problems in the vt220 intialization: o Currently the vt220 console looses early printk events until the the vt220 tty is registered. o console should work if tty_register fails sclp_vt220_con_init calls __sclp_vt220_init and register_console. It does not register the driver with the sclp core code via sclp_register. That results in an sclp_send_mask=0. Therefore, __sclp_vt220_emit will reject buffers with EIO. Unfortunately register_console will cause the printk buffer to be sent to the console and, therefore, every early message gets dropped. The sclp_send_mask is set later during boot, when sclp_vt220_tty_init calls sclp_register. The solution is to move the sclp_register call from sclp_vt220_tty_init to __sclp_vt220_init. This makes sure that the console is properly registered with the sclp subsystem before the first log buffer messages are passed to the vt220 console. We also adopt the cleanup on error to keep the console alive if tty_register fails. Thanks to Peter Oberparleiter and Heiko Carstens for review and ideas for improvement. Signed-off-by:

If qdio establish runs in parallel with a channel error, ccw_device_start_timeout may not trigger the qdio_timeout_handler. In this case neither QDIO_IRQ_STATE_ESTABLISHED nor QDIO_IRQ_STATE_ERR is reached and the following wait_event hangs forever. Solution: do not make use of the timeout option with ccw_device_start, but add a timeout to the following wait_event. Signed-off-by:
