[S390] cleanup psw related bits and pieces

2011-10-30T14:16:43+00:00

Split out addressing mode bits from PSW_BASE_BITS, rename PSW_BASE_BITS
to PSW_MASK_BASE, get rid of psw_user32_bits, remove unused function
enabled_wait(), introduce PSW_MASK_USER, and drop PSW_MASK_MERGE macros.
Change psw_kernel_bits / psw_user_bits to contain only the bits that
are always set in the respective mode.

[S390] sclp: avoid 64 bit division

2010-03-24T10:49:53+00:00

Avoid 64 bit division to fix this compile error on 32 bit:
drivers/s390/char/sclp_cmd.c:711: undefined reference to `__udivdi3'

Also move the whole arch_get_memory_phys_device function to the
memory hotplug related functions.

memory hotplug/s390: set phys_device

2010-03-18T01:43:47+00:00

Implement arch specific arch_get_memory_phys_device function and
initialize phys_device for each memory section.  That way we finally can
tell which piece of memory belongs to which physical device.

This makes s390's /sys/devices/system/memory/memoryX/phys_device display
the correct thing?

[S390] fix "mem=" handling in case of standby memory

2009-02-19T14:19:19+00:00

Standby memory detected with the sclp interface gets always registered
with add_memory calls without considering the limitationt that the
"mem=" kernel paramater implies.
So fix this and only register standby memory that is below the specified
limit.
This fixes zfcpdump since it uses "mem=32M". In case there is appr.
2GB standby memory present all of usable memory would be used for the
struct pages needed for standby memory.
