linux6.x: backport fix for kexec regression
All of our `linux6.x` kernel series include a change that breaks `kexec` on certain hardware, notably AMD CPUs using various iterations of the Zen microarchitecture. I can reproduce the issue on my Zen 3 CPU, while [other reports](https://github.com/zbm-dev/zfsbootmenu/discussions/598) reveal that this problem affects ZFSBootMenu users on other iterations. I bisected the problem and confirmed that it is caused by the same commit that [seems to impact users more generally](https://lore.kernel.org/all/3a1b9909-45ac-4f97-ad68-d16ef1ce99db@pavinjoseph.com/). Consequently, the current upstream fix is to [just revert the change](https://lore.kernel.org/linux-kernel/8142c0de-e3a4-4e78-aa1b-f5e6503752e4@intel.com/T/#m674760504b865936068602efca9a10fb72e7102e).
While I was backporting the reversion, I took the liberty of updating `linux6.1` as well.
I'm in the process of building and testing kernels with these patches to confirm that it fixes the ZFSBootMenu problem I observed and, assuming so, plan to bump our kernels to include the fix.

Yes, that commit should be reverted, seeing that in urgency, I think there'll be a stable release soon, no?

Comment:
I've built these kernels for aarch64 and x86_64 and confirm that the revert fixes booting with ZFSBootMenu for every kernel series in this PR.
We can wait a day or two to see if new kernels are forthcoming. I see some announcements for 6.1 and 6.6 RC windows, but the revert does not appear in the changelog. We should make sure this is included in the next release, or we'll have to carry patches for awhile.

There is an updated pull request by ahesford against master on the void-packages repository
https://github.com/ahesford/void-packages kexec-regression
https://github.com/void-linux/void-packages/pull/49529
linux6.x: backport fix for kexec regression
All of our `linux6.x` kernel series include a change that breaks `kexec` on certain hardware, notably AMD CPUs using various iterations of the Zen microarchitecture. I can reproduce the issue on my Zen 3 CPU, while [other reports](https://github.com/zbm-dev/zfsbootmenu/discussions/598) reveal that this problem affects ZFSBootMenu users on other iterations. I bisected the problem and confirmed that it is caused by the same commit that [seems to impact users more generally](https://lore.kernel.org/all/3a1b9909-45ac-4f97-ad68-d16ef1ce99db@pavinjoseph.com/). Consequently, the current upstream fix is to [just revert the change](https://lore.kernel.org/linux-kernel/8142c0de-e3a4-4e78-aa1b-f5e6503752e4@intel.com/T/#m674760504b865936068602efca9a10fb72e7102e).
While I was backporting the reversion, I took the liberty of updating `linux6.1` as well.
I'm in the process of building and testing kernels with these patches to confirm that it fixes the ZFSBootMenu problem I observed and, assuming so, plan to bump our kernels to include the fix.

There is an updated pull request by ahesford against master on the void-packages repository
https://github.com/ahesford/void-packages kexec-regression
https://github.com/void-linux/void-packages/pull/49529
linux6.x: backport fix for kexec regression
All of our `linux6.x` kernel series include a change that breaks `kexec` on certain hardware, notably AMD CPUs using various iterations of the Zen microarchitecture. I can reproduce the issue on my Zen 3 CPU, while [other reports](https://github.com/zbm-dev/zfsbootmenu/discussions/598) reveal that this problem affects ZFSBootMenu users on other iterations. I bisected the problem and confirmed that it is caused by the same commit that [seems to impact users more generally](https://lore.kernel.org/all/3a1b9909-45ac-4f97-ad68-d16ef1ce99db@pavinjoseph.com/). Consequently, the current upstream fix is to [just revert the change](https://lore.kernel.org/linux-kernel/8142c0de-e3a4-4e78-aa1b-f5e6503752e4@intel.com/T/#m674760504b865936068602efca9a10fb72e7102e).
While I was backporting the reversion, I took the liberty of updating `linux6.1` as well.
I'm in the process of building and testing kernels with these patches to confirm that it fixes the ZFSBootMenu problem I observed and, assuming so, plan to bump our kernels to include the fix.

There is an updated pull request by ahesford against master on the void-packages repository
https://github.com/ahesford/void-packages kexec-regression
https://github.com/void-linux/void-packages/pull/49529
linux6.x: backport fix for kexec regression
All of our `linux6.x` kernel series include a change that breaks `kexec` on certain hardware, notably AMD CPUs using various iterations of the Zen microarchitecture. I can reproduce the issue on my Zen 3 CPU, while [other reports](https://github.com/zbm-dev/zfsbootmenu/discussions/598) reveal that this problem affects ZFSBootMenu users on other iterations. I bisected the problem and confirmed that it is caused by the same commit that [seems to impact users more generally](https://lore.kernel.org/all/3a1b9909-45ac-4f97-ad68-d16ef1ce99db@pavinjoseph.com/). Consequently, the current upstream fix is to [just revert the change](https://lore.kernel.org/linux-kernel/8142c0de-e3a4-4e78-aa1b-f5e6503752e4@intel.com/T/#m674760504b865936068602efca9a10fb72e7102e).
While I was backporting the reversion, I took the liberty of updating `linux6.1` as well.
I'm in the process of building and testing kernels with these patches to confirm that it fixes the ZFSBootMenu problem I observed and, assuming so, plan to bump our kernels to include the fix.

+Subject: Revert "x86/mm/ident_map: Use gbpages only where full GB page should
+ be mapped."
+
+This reverts commit d794734c9bbfe22f86686dc2909c25f5ffe1a572.
+
+While the original change tries to fix a bug, it also unintentionally broke
+existing systems, see the regressions reported at:
+
+ https://lore.kernel.org/all/3a1b9909-45ac-4f97-ad68-d16ef1ce99db@pavinjoseph.com/
+
+Since d794734c9bbf was also marked for -stable, let's back it out before
+causing more damage.
+
+Note that due to another upstream change the revert was not 100% automatic:
+
+ 0a845e0f6348 mm/treewide: replace pud_large() with pud_leaf()

There is an updated pull request by ahesford against master on the void-packages repository

linux6.x: backport fix for kexec regression
All of our `linux6.x` kernel series include a change that breaks `kexec` on certain hardware, notably AMD CPUs using various iterations of the Zen microarchitecture. I can reproduce the issue on my Zen 3 CPU, while [other reports](https://github.com/zbm-dev/zfsbootmenu/discussions/598) reveal that this problem affects ZFSBootMenu users on other iterations. I bisected the problem and confirmed that it is caused by the same commit that [seems to impact users more generally](https://lore.kernel.org/all/3a1b9909-45ac-4f97-ad68-d16ef1ce99db@pavinjoseph.com/). Consequently, the current upstream fix is to [just revert the change](https://lore.kernel.org/linux-kernel/8142c0de-e3a4-4e78-aa1b-f5e6503752e4@intel.com/T/#m674760504b865936068602efca9a10fb72e7102e).
While I was backporting the reversion, I took the liberty of updating `linux6.1` as well.
I'm in the process of building and testing kernels with these patches to confirm that it fixes the ZFSBootMenu problem I observed and, assuming so, plan to bump our kernels to include the fix.

+Subject: Revert "x86/mm/ident_map: Use gbpages only where full GB page should
+ be mapped."
+
+This reverts commit d794734c9bbfe22f86686dc2909c25f5ffe1a572.
+
+While the original change tries to fix a bug, it also unintentionally broke
+existing systems, see the regressions reported at:
+
+ https://lore.kernel.org/all/3a1b9909-45ac-4f97-ad68-d16ef1ce99db@pavinjoseph.com/
+
+Since d794734c9bbf was also marked for -stable, let's back it out before
+causing more damage.
+
+Note that due to another upstream change the revert was not 100% automatic:
+
+ 0a845e0f6348 mm/treewide: replace pud_large() with pud_leaf()

Looks like Alpine found a fix, so I'm build-testing all of them again.

There's a merged pull request on the void-packages repository
linux6.x: backport fix for kexec regression
https://github.com/void-linux/void-packages/pull/49529
Description:
All of our `linux6.x` kernel series include a change that breaks `kexec` on certain hardware, notably AMD CPUs using various iterations of the Zen microarchitecture. I can reproduce the issue on my Zen 3 CPU, while [other reports](https://github.com/zbm-dev/zfsbootmenu/discussions/598) reveal that this problem affects ZFSBootMenu users on other iterations. I bisected the problem and confirmed that it is caused by the same commit that [seems to impact users more generally](https://lore.kernel.org/all/3a1b9909-45ac-4f97-ad68-d16ef1ce99db@pavinjoseph.com/). Consequently, the current upstream fix is to [just revert the change](https://lore.kernel.org/linux-kernel/8142c0de-e3a4-4e78-aa1b-f5e6503752e4@intel.com/T/#m674760504b865936068602efca9a10fb72e7102e).
While I was backporting the reversion, I took the liberty of updating `linux6.1` as well.
I'm in the process of building and testing kernels with these patches to confirm that it fixes the ZFSBootMenu problem I observed and, assuming so, plan to bump our kernels to include the fix.
