deprecated ENTRY(), ENDPROC(), etc. family of macros.

s390/tty3270: add support for diag 8c

2023-01-09T13:33:56+00:00

The current code uses diag210 to infer the 3270 geometry from the
model number when running on z/VM. This doesn't work well as almost
all 3270 software clients report as 3279-2 with a custom resolution.
tty3270 assumes it has a 80x24 terminal connected because of the -2
suffix. Use diag 8c to fetch the realy geometry from z/VM.

Note that this doesn't allow dynamic resizing, i.e. reconnecting to
a z/VM session with a different geometry.

s390/extable: move EX_TABLE define to asm-extable.h

2022-03-07T23:33:00+00:00

Follow arm64 and riscv and move the EX_TABLE define to asm-extable.h
which is a lot less generic than the current linkage.h.

Also make sure that all files which contain EX_TABLE usages actually
include the new header file. This should make sure that the files
always compile and there won't be any random compile breakage due to
other header file dependencies.

s390/diag: make restart_part2 a local label

2021-08-25T09:03:34+00:00

Avoid that the "restart_part2" label, which is in the middle of a
function, appears in /proc/kallsyms.

s390: rename dma section to amode31

2021-08-05T12:10:53+00:00

The dma section name is confusing, since the code which resides within
that section has nothing to do with direct memory access.  Instead the
limitation is that the code has to run in 31 bit addressing mode, and
therefore has to reside below 2GB.  So the name was chosen since
ZONE_DMA is the same region.

To reduce confusion rename the section to amode31, which hopefully
describes better what this is about.

Note: this will also change vmcoreinfo strings
- SDMA=... gets renamed to SAMODE31=...
- EDMA=... gets renamed to EAMODE31=...
