MIPS: Ignore relocs against __ex_table for relocatable kernel

2025-02-27T10:07:50+00:00

Since commit 6f2c2f93a190 ("scripts/sorttable: Remove unneeded
Elf_Rel"), sorttable no longer clears relocs against __ex_table,
claiming "it was never used."  But in fact MIPS relocatable kernel had
been implicitly depending on this behavior, so after this commit the
MIPS relocatable kernel has started to spit oops like:

	CPU 1 Unable to handle kernel paging request at virtual address 000000fffbbdbff8, epc == ffffffff818f9a6c, ra == ffffffff813ad7d0
	... ...
	Call Trace:
	[] __raw_copy_from_user+0x48/0x2fc
	[] cp_statx+0x1a0/0x1e0
	[] do_statx_fd+0xa8/0x118
	[] sys_statx+0xd8/0xf8
	[] syscall_common+0x34/0x58

So ignore those relocs on our own to fix the issue.

Merge tag 'char-misc-6.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

2025-01-28T00:51:51+00:00

Pull Char/Misc/IIO driver updates from Greg KH:
 "Here is the "big" set of char/misc/iio and other smaller driver
  subsystem updates for 6.14-rc1. Loads of different things in here this
  development cycle, highlights are:

   - ntsync "driver" to handle Windows locking types enabling Wine to
     work much better on many workloads (i.e. games). The driver
     framework was in 6.13, but now it's enabled and fully working
     properly. Should make many SteamOS users happy. Even comes with
     tests!

   - Large IIO driver updates and bugfixes

   - FPGA driver updates

   - Coresight driver updates

   - MHI driver updates

   - PPS driver updatesa

   - const bin_attribute reworking for many drivers

   - binder driver updates

   - smaller driver updates and fixes

  All of these have been in linux-next for a while with no reported
  issues"

MIPS: migrate to generic rule for built-in DTBs

2025-01-11T12:53:42+00:00

Commit 654102df2ac2 ("kbuild: add generic support for built-in boot
DTBs") introduced generic support for built-in DTBs.

Select GENERIC_BUILTIN_DTB and BUILTIN_DTB_ALL when the built-in DTB
support is enabled.

DTBs compiled under arch/mips/boot/dts/ will be wrapped by the generic
rule in scripts/Makefile.vmlinux.

MIPS: Loongson64: DTS: Really fix PCIe port nodes for ls7a

2024-11-23T10:53:21+00:00

Fix the dtc warnings:

    arch/mips/boot/dts/loongson/ls7a-pch.dtsi:68.16-416.5: Warning (interrupt_provider): /bus@10000000/pci@1a000000: '#interrupt-cells' found, but node is not an interrupt provider
    arch/mips/boot/dts/loongson/ls7a-pch.dtsi:68.16-416.5: Warning (interrupt_provider): /bus@10000000/pci@1a000000: '#interrupt-cells' found, but node is not an interrupt provider
    arch/mips/boot/dts/loongson/loongson64g_4core_ls7a.dtb: Warning (interrupt_map): Failed prerequisite 'interrupt_provider'

And a runtime warning introduced in commit 045b14ca5c36 ("of: WARN on
deprecated #address-cells/#size-cells handling"):

    WARNING: CPU: 0 PID: 1 at drivers/of/base.c:106 of_bus_n_addr_cells+0x9c/0xe0
    Missing '#address-cells' in /bus@10000000/pci@1a000000/pci_bridge@9,0

The fix is similar to commit d89a415ff8d5 ("MIPS: Loongson64: DTS: Fix PCIe
port nodes for ls7a"), which has fixed the issue for ls2k (despite its
subject mentions ls7a).

the main eyeq5.dtsi file.
