[S390] facility detection: remove unused variable

2010-10-29T14:50:50Z

arch/s390/kernel/early.c: In function 'setup_hpage': arch/s390/kernel/early.c:285:15: warning: unused variable 'facilities' Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky

[S390] topology: clean up facility detection

2010-10-25T14:10:21Z

Move cpu topology facility detection to early setup code where it should be. Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky

[S390] cleanup facility list handling

2010-10-25T14:10:21Z

Store the facility list once at system startup with stfl/stfle and reuse the result for all facility tests. Signed-off-by: Martin Schwidefsky

[S390] add support for nonquiescing sske

2010-10-25T14:10:15Z

Improve performance of the sske operation by using the nonquiescing variant if the affected page has no mappings established. On machines with no support for the new sske variant the mask bit will be ignored. Signed-off-by: Martin Schwidefsky

[S390] virtualization aware cpu measurement

2010-05-17T08:00:15Z

Use the SPP instruction to set a tag on entry to / exit of the virtual machine context. This allows the cpu measurement facility to distinguish the samples from the host and the different guests. Signed-off-by: Carsten Otte

[S390] nss: add missing .previous statement to asm function

2010-04-09T11:43:02Z

The savesys_ipl_nss asm function is put into the .init.text section however it is missing a ".previous" section which would restore the previous section. Luckily all functions in early.c are init functions so it doesn't matter currently. Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky

[S390] codepage conversion of kernel parameter line

2010-02-26T21:37:32Z

Move the ebcdic to ascii conversion of the kernel parameter line from head.S to early.c and convert the assembler code to C. Signed-off-by: Martin Schwidefsky

[S390] add MACHINE_IS_LPAR flag

2010-02-26T21:37:31Z

Introduce the MACHINE_IS_LPAR flag for code that should only be executed if Linux is running in an LPAR. Signed-off-by: Martin Schwidefsky

[S390] reset cputime accounting after IPL from NSS

2009-11-13T14:45:03Z

After an IPL from NSS the uptime of the system is incorrect. The reason is that the startup code in head.S is not executed in case of an IPL from NSS. Due to that sched_clock_base_cc which is used to initialze wall_to_monotonic contains the time stamp when the NSS has been created instead of the time stamp of the system start. Reinitialize the cputime accounting values in create_kernel_nss after the SAVESYS CP command that created the NSS segment. Signed-off-by: Martin Schwidefsky

[S390] kernel: Print an error message if kernel NSS cannot be defined

2009-09-11T08:29:51Z

If a named saved system (NSS) cannot be defined or saved, print out an error message with the return code of the underlying z/VM CP command. Signed-off-by: Hendrik Brueckner Signed-off-by: Martin Schwidefsky
