* [GIT PULL] RISC-V Patches for the 5.10 Merge Window, Part 1 @ 2020-10-19 19:08 Palmer Dabbelt 2020-10-19 20:43 ` Atish Patra ` (2 more replies) 0 siblings, 3 replies; 7+ messages in thread From: Palmer Dabbelt @ 2020-10-19 19:08 UTC (permalink / raw) To: Linus Torvalds; +Cc: linux-riscv, linux-kernel The following changes since commit d012a7190fc1fd72ed48911e77ca97ba4521bccd: Linux 5.9-rc2 (2020-08-23 14:08:43 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux.git tags/riscv-for-linus-5.10-mw0 for you to fetch changes up to de22d2107ced3cc5355cc9dbbd85e44183546bd5: RISC-V: Add page table dump support for uefi (2020-10-02 14:31:33 -0700) ---------------------------------------------------------------- RISC-V Patches for the 5.10 Merge Window, Part 1 This contains a handful of cleanups and new features, including: * A handful of cleanups for our page fault handling. * Improvements to how we fill out cacheinfo. * Support for EFI-based systems. --- This contains a merge from the EFI tree that was necessary as some of the EFI support landed over there. It's my first time doing something like this, I haven't included the set_fs stuff because the base branch it depends on hasn't been merged yet. I'll probably have another merge window PR, as there's more in flight (most notably the fix for new binutils I just sent out), but I figured there was no reason to delay this any longer. There is one merge conflict, which is between my fixes and for-next branches: diff --cc arch/riscv/kernel/vmlinux.lds.S index 67db80e12d1f,9795359cb9da..ffaa3da375c2 --- a/arch/riscv/kernel/vmlinux.lds.S +++ b/arch/riscv/kernel/vmlinux.lds.S @@@ -66,8 -71,11 +70,13 @@@ SECTION _etext = .; } + INIT_DATA_SECTION(16) + + #ifdef CONFIG_EFI + . = ALIGN(PECOFF_SECTION_ALIGNMENT); + __pecoff_text_end = .; + #endif + /* Start of data section */ _sdata = .; RO_DATA(SECTION_ALIGN) ---------------------------------------------------------------- Anup Patel (1): RISC-V: Move DT mapping outof fixmap Ard Biesheuvel (3): efi/libstub: arm32: Base FDT and initrd placement on image address efi/libstub: Export efi_low_alloc_above() to other units efi/libstub: arm32: Use low allocation for the uncompressed kernel Atish Patra (8): include: pe.h: Add RISC-V related PE definition efi: Rename arm-init to efi-init common for all arch RISC-V: Add early ioremap support RISC-V: Implement late mapping page table allocation functions RISC-V: Add PE/COFF header for EFI stub RISC-V: Add EFI stub support.

I guess I just assumed they were supposed to show up in the shortlog, but it's my first time trying one of these multi-tree merges so maybe I screwed something up?

OK, good to know -- I'd just been pointing my PRs at Linus' latest tag, rather than directly at master, as it's less of a moving target. Sounds like that's a reasonable thing to do, so I'll probably keep doing it (unless I forget ;)) Linus: Looks like this was all actually fine, but LMK if you have any issues. _______________________________________________ linux-riscv mailing list linux-riscv@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-riscv ^ permalink raw reply [flat|nested] 7+ messages in thread

I put the INIT_DATA_SECTION after the __pecoff_text_end symbol. I don't think INIT_DATA_SECTION should be considered text I suspect it doesn't matter, but if there is some odd dependency that I missed, this is a heads-up that my resolution doesn't look exactly like the above.
