Jack Steiner ed5316d445 [PATCH] x86-64: - Ignore long SMI interrupts in clock calibration
Ensure that no SMI interrupts occur between the read of the HPET & TSC
in the clock calibration loop.

I noticed that a 2.66GHz system incorrectly detected the processor
clock speed about 1/7 of the time:

	time.c: Detected 2660.005 MHz processor.	(most of the time)
	time.c: Detected 2988.203 MHz processor.	(sometime)

The problem is caused by an SMI interrupt occuring in hpet_calibrate_tsc()
between the read of the HPET & TSC. Prior to switching the BIOS into
ACPI mode, it appears that every 27msec an SMI interrupt occurs. The
SMI interrupt takes 4.8 msec to process.

Note: On my test system, TICK_MIN had to be >380. I picked 5000
to minimize risk of having a value that is too small for other
platforms.

Vivek Goyal ee6a8545a4 [PATCH] x86-64: Modpost whitelist reference to more symbols (pattern 3)
o MODPOST generates warning on i386 if kernel is compiled with
  CONFIG_RELOCATABLE=y.

WARNING: vmlinux - Section mismatch: reference to .init.text:_einittext from .text between 'get_symbol_pos' (at offset 0xc013577d) and 'reset_iter'

o These symbols (__init_begin, _sinittext, _einittext) belong to init
  section and generally represent a section boundary. These are special
  symbols in the sense that their size is zero and no memory is allocated
  for them in init section. Their addr and value are same. So even if
  we free the init section, it is ok to reference them.

o Whitelist access to such select symbols in MODPOST.

Vivek Goyal 118c0ace1b [PATCH] x86-64: modpost add more symbols to whitelist pattern2
o MODPOST generates warning for i386 if compiled with CONFIG_RELOCATABLE=y
  and serial console support is enabled.

o Serial console setup function, serial8250_console_setup(), is a non __init
  function and it calls functions which are of type __init().
  (uart_parse_options() and uart_set_options()). Assuming, setup will
  be called during init time, changing serial8250_console_setup() to __init.

o Adding one more pattern to modpost whitelist. Console drivers might
  have *_console structures containing references to setup functions which
  can be of __init type. Don't generate warnings for those.

Vivek Goyal e96763d6e5 [PATCH] i386: make apic probe function non-init
o struct genapic contains pointer to probe() function which is of type
  __init. Hence MODPOST generates warning if kernel is compiled with
  CONFIG_RELOCATABLE=y for i386.

WARNING: vmlinux - Section mismatch: reference to .init.text: from .data between 'apic_summit' (at offset 0xc058b504) and 'apic_bigsmp'
WARNING: vmlinux - Section mismatch: reference to .init.text: from .data between 'apic_bigsmp' (at offset 0xc058b5a4) and 'cpu.4471'

WARNING: vmlinux - Section mismatch: reference to .init.text: from .data between 'apic_default' (at offset 0xc058b6e4) and 'interrupt'

o One of the possible options is to put special case check in MODPOST to
  not emit warnings for this case but I think it is not a very good option
  in terms of maintenance.

o Another option is to make probe() function non __init. Anyway this function
  is really small so not freeing this memory after init is not a big deal.
  Secondly, from a programming perspective, probably genapic should not
  provide pointers to functions which have been freed as genapic is non
  __init and is used even after initialization is complete.

Vivek Goyal 4a5d107a9a [PATCH] i386: cpu hotplug/smpboot misc MODPOST warning fixes
o Misc smpboot/cpu hotplug path cleanups. I did those to supress the
  warnings generated by MODPOST. These warnings are visible only
  if CONFIG_RELOCATABLE=y.

o CONFIG_RELOCATABLE compiles the kernel with --emit-relocs option. This
  option retains relocation information in vmlinux file and MODPOST
  is quick to spit out "Section mismatch" warnings.

o This patch fixes some of those warnings. Many of the functions in
  smpboot case are __devinit type and they in turn accesses text/data which
  if of type __cpuinit. Now if CONFIG_HOTPLUG=y and CONFIG_HOTPLUG_CPU=n
  then we end up in cases where a function in .text segment is calling
  another function in .init.text segment and MODPOST emits warning.

WARNING: vmlinux - Section mismatch: reference to .init.text:identify_cpu from .text between 'smp_store_cpu_info' (at offset 0xc011020d) and 'do_boot_cpu'
WARNING: vmlinux - Section mismatch: reference to .init.text:init_gdt from .text between 'do_boot_cpu' (at offset 0xc01102ca) and '__cpu_up'
WARNING: vmlinux - Section mismatch: reference to .init.text:print_cpu_info from .text between 'do_boot_cpu' (at offset 0xc01105d0) and '__cpu_up'

o It also fixes the issues where CONFIG_HOTPLUG_CPU=y and start_secondary()
  is calling smp_callin() which in-turn calls synchronize_tsc_ap() which is
  of type __init. This should have meant broken CPU hotplug.

Alexander Bigga 8a93c4968f [MIPS] Alchemy: Fix PCI-memory access
The problem was introduced in 2.6.18.3 with the casting of some
    36bit-defines (PCI memory) in au1000.h to resource_size_t which may be
    u32 or u64 depending on the experimental CONFIG_RESOURCES_64BIT.
    
    With unset CONFIG_RESOURCES_64BIT, the pci-memory cannot be accessed
    because the ioremap in arch/mips/au1000/common/pci.c already used the
    truncated addresses.
    With set CONFIG_RESOURCES_64BIT, things get even worse, because PCI-scan
    aborts, due to resource conflict: request_resource() in arch/mips/pci/pci.c
    fails because the maximum iomem-address is 0xffffffff (32bit) but the
    pci-memory-start-address is 0x440000000 (36bit).
    
    To get pci working again, I propose the following patch:
    
    1. remove the resource_size_t-casting from au1000.h again
    2. make the casting in arch/mips/au1000/common/pci.c (it's allowed and
    necessary here. The 36bit-handling will be done in __fixup_bigphys_addr).
    
    With this patch pci works again like in 2.6.18.2, the gcc-compile warnings
    in pci.c are gone and it doesn't depend on CONFIG_EXPERIMENTAL.

Stefan Richter 1a74bc68e4 ieee1394: sbp2: fix probing of some DVD-ROM/RWs
Since commit 98e238cd42 in Linux 2.6.19,
"ieee1394: sbp2: don't prefer MODE SENSE 10", some FireWire DVD-ROMs and
DVD-RWs were mistaken as CD-ROM because sr_mod now sent MODE SENSE 6.
The MMC command set includes only MODE SENSE 10.
http://bugzilla.kernel.org/show_bug.cgi?id=7800

This fix lets sbp2 switch scsi_device.use_10_for_rw on for MMC LUs.
This should rather be done in the command set driver sr_mod, not in the
sbp2 transport driver, and an according patch will follow for a next
Linux release.

Hoang-Nam Nguyen f2d9136133 IB/ehca: Use proper GFP_ flags for get_zeroed_page()
Here is a patch for ehca to use proper flag, ie. GFP_ATOMIC
resp. GFP_KERNEL, when calling get_zeroed_page() to prevent "Bug:
scheduling while atomic...". This error does not cause a kernel panic
but makes ipoib un-usable afterwards.  It is reproducible on
2.6.20-rc4 if one does ifconfig down during a flood ping test.  I have
not observed this error in earlier releases incl. 2.6.20-rc1.

This error occurs when a qp event/irq is received and ehca event
handler allocates a control block/page to obtain HCA error data block.
Use of GFP_ATOMIC when in interrupt context prevents this issue.

Mark M. Hoffman 2f5c33b318 [PATCH] i2c/pci: fix sis96x smbus quirk once and for all
The sis96x SMBus PCI device depends on two different quirks to run
in a specific order.  Apart from being fragile, this was found to
actually break on (at least) recent FC4, FC5, and FC6 kernels.  This
patch fixes the quirks so that they work without relying on the
compiler and/or linker to put them in any specific order.

Christian Borntraeger bf3dbdcd0b [S390] locking problem with __cpcmd.
Changeset 740b5706b9 moved the protecting
spinlock from __cpcmd to cpcmd. Therefore vmcp can no longer use __cpcmd,
instead we have to use cpcmd.

Heiko Carstens d8ad075ef6 [S390] don't call handle_mm_fault() if in an atomic context.
There are several places in the futex code where a spin_lock is held
and still uaccesses happen. Deadlocks are avoided by increasing the
preempt count. The pagefault handler will then not take any locks
but will immediately search the fixup tables.

Heiko Carstens de338a3795 [S390] Fix vmalloc area size calculation.
setup_memory_end() uses VMALLOC_END instead of VMALLOC_END_INIT to
calculate the maximum supported size of physical memory. Since
VMALLOC_END is zero, this will cause a crash on 31 bit systems.

72486f1f8f inverts the logic if an

Heiko Carstens 6faf4444f2 [S390] cio: use barrier() in stsch_reset.
Use barrier() in stsch_reset() instead of duplicating the stsch()
inline assembly and adding "memory" to the clobberlist.
Pointed out by Chuck Ebbert.

Real fix would be to add a fixup section to the stsch() and extend the
basic program check handler so it searches the exception tables in case
of a program check.
