2016-05-05ACPICA: Divergence: remove unwanted spaces for typedefLv Zheng1-4/+3
ACPICA commit b2294cae776f5a66a7697414b21949d307e6856f This patch removes unwanted spaces for typedef. This solution doesn't cover function types. Note that the linuxize result of this commit is very giant and should have many conflicts against the current Linux upstream. Thus it is required to modify the linuxize result of this commit and the commits around it manually in order to have them merged to the Linux upstream. Since this is very costy, we should do this only once, and if we can't ensure to do this only once, we need to revert the Linux code to the wrong indentation result before merging the linuxize result of this commit.

2013-10-30ACPICA: Hardcode access width for the reset register.Bob Moore1-2/+8
The ACPI spec requires the reset register width to be 8, so we now hardcode it and ignore the FADT value.

2013-01-10ACPICA: Cleanup updated comments.Lv Zheng1-5/+5
This is a cosmetic patch only. Comparison of the resulting binary showed only line number differences. This patch does not affect the generation of the Linux binary. This patch decreases 558 lines of 20121018 divergence.diff. This patch reduces the source code diff between Linux and ACPICA by cleaning the comments that already have been updated in ACPICA. There is no extra indentation done in this patch. Even the empty line deletions and insertions are also splitted into another cleanup patch so that this patch can be easily reviewed, and the binary differences can be held to a lowest level.

2012-04-20Revert "ACPI: ignore FADT reset-reg-sup flag"Linus Torvalds1-1/+2
This reverts commit cf450136bfde77c7f95065c91bffded4aa7fa731. It breaks reboot on at least one Thinkpad T43, as reported by Jörg Otte: "On reboot it shuts down as normal. The last lines displayed are: >Unmounting temporary filesystems.. [OK] >Deactivating swap... [OK] >Unmounting local filesystems... [OK] >Will now restart > Restarting system Then I hear it accessing the cd-drive, but then it's being stuck." Jörg bisected the regression to this commit. That commit fixes another machine (see https://bugzilla.kernel.org/show_bug.cgi?id=11533 for details) that has a BIOS bug and doesn't support ACPI reset. However, at least one of those other reporters no longer even has the machine in question, and had a different workaround to begin with. Besides, it clearly was a buggy BIOS. Let's not break the correct case to fix that case.

Note: The internal acpi_hw_read and acpi_hw_write interfaces remain at 32 bits, because 64 bits is not needed to access the standard ACPI registers.
