ia64: fix build error with !COREDUMP

2020-10-18T16:27:09+00:00

Fix linkage error when CONFIG_BINFMT_ELF is selected but CONFIG_COREDUMP
is not:

    ia64-linux-ld: arch/ia64/kernel/elfcore.o: in function `elf_core_write_extra_phdrs':
    elfcore.c:(.text+0x172): undefined reference to `dump_emit'
    ia64-linux-ld: arch/ia64/kernel/elfcore.o: in function `elf_core_write_extra_data':
    elfcore.c:(.text+0x2b2): undefined reference to `dump_emit'

Fixes: 1fcccbac89f5 ("elf coredump: replace ELF_CORE_EXTRA_* macros by functions")

2020-09-11T16:34:32+00:00

perfmon has been marked broken and thus been disabled for all builds
for more than two years.  Remove it entirely.

ia64: remove support for machvecs

2019-08-16T21:32:26+00:00

The only thing remaining of the machvecs is a few checks if we are
running on an SGI UV system.  Replace those with the existing
is_uv_system() check that has been rewritten to simply check the
OEM ID directly.

That leaves us with a generic kernel that is as fast as the previous
DIG/ZX1/UV kernels, but can support all hardware.  Support for UV
and the HP SBA IOMMU is now optional based on new config options.

ia64: remove CONFIG_ACPI ifdefs

2019-08-16T18:33:57+00:00

Now that hpsim support is gone, CONFIG_ACPI is forced on for ia64, and
we can remove a few ifdefs for it.

ia64: remove the hpsim platform

2019-08-16T18:33:57+00:00

The hpsim platform supports the HP IA64 simulator which was useful as a
bring up platform.  But it is fairly non-standard vs real IA64 system
in that it for example doesn't support ACPI.  It also comes with a
whole bunch of simulator specific drivers.  Remove it to simplify the
IA64 port.

Note that through a weird twist only them hpsim boot loader built the
vmlinux.gz file, so the makefile targets for that are moved to the
main ia64 Makefile now.

treewide: add intermediate .s files to targets

treewide: remove explicit rules for *offsets.s

2018-12-23T01:12:03+00:00

These explicit rules are unneeded because scripts/Makefile.build
provides a pattern rule to create %.s from %.c

ia64/kprobes: Remove jprobe implementation

2018-06-21T10:33:09+00:00

Remove arch dependent setjump/longjump functions
and unused fields in kprobe_ctlblk for jprobes
from arch/ia64.

Note that since ia64 jprobes code is a bit different
from other architectures, this keeps __IA64_BREAK_JPROBE
for checking the ->break_handler(). It will be removed
with the break_handler() calls afterwards.

ia64: fix build failure with CONFIG_SWIOTLB

2018-02-12T15:59:05+00:00

arch/ia64/kernel/pci-swiotlb.c is removed in commit 4fac8076df85 ("ia64: clean up swiotlb support")
but pci-swiotlb.o is still present in Makefile, and so build fail when
CONFIG_SWIOTLB is enabled.

Construct init thread stack in the linker script rather than by union

2018-01-09T23:21:02+00:00

Construct the init thread stack in the linker script rather than doing it
by means of a union so that ia64's init_task.c can be got rid of.

The following symbols are then made available from INIT_TASK_DATA() linker
script macro:

	init_thread_union
	init_stack

INIT_TASK_DATA() also expands the region to THREAD_SIZE to accommodate the
size of the init stack.  init_thread_union is given its own section so that
it can be placed into the stack space in the right order.  I'm assuming
that the ia64 ordering is correct and that the task_struct is first and the
thread_info second.
